Pelvic pain is a common but medically complex symptom that can arise from many different organs and tissues. It may originate from the reproductive organs, urinary tract, gastrointestinal system, pelvic floor muscles, nerves, bones, or abdominal wall. In some people, several conditions contribute to the pain at the same time.
Pelvic pain may be acute, developing suddenly over hours or days, or chronic, persisting for months or recurring over a prolonged period. The distinction is clinically important because acute pelvic pain may indicate a medical or surgical emergency, while chronic pelvic pain often requires a broader, multidisciplinary approach.
In women, pelvic pain can be associated with conditions such as menstrual cramps, endometriosis, ovarian cysts, pelvic inflammatory disease, uterine fibroids, adenomyosis, ovarian torsion, ectopic pregnancy, and complications of pregnancy. However, pelvic pain is not exclusively a gynecological problem. Urinary tract infections, kidney stones, appendicitis, irritable bowel syndrome, inflammatory bowel disease, constipation, hernias, pelvic-floor disorders, and musculoskeletal conditions can all produce pain in the pelvic region.
Men can also experience pelvic pain. Important causes include prostatitis, urinary tract infections, kidney or ureteric stones, inguinal hernias, pelvic-floor dysfunction, gastrointestinal disease, and chronic pelvic pain syndromes.
Because the pelvis contains numerous closely connected structures, pain from one organ can sometimes feel as though it is coming from another. For this reason, diagnosing pelvic pain often requires careful history-taking, physical examination, laboratory testing, and, when appropriate, imaging.
The most important principle is that pelvic pain should not automatically be assumed to be harmless. Sudden severe pain, pain associated with pregnancy, fainting, heavy bleeding, fever, vomiting, abdominal rigidity, or signs of shock can indicate a potentially life-threatening condition and requires urgent medical evaluation.
1. What Is Pelvic Pain?
Pelvic pain is discomfort or pain perceived in the lower abdomen, pelvis, or structures surrounding the pelvic cavity.
The pain may be felt:
- Below the umbilicus
- Above the pubic bone
- In the lower abdomen
- In the groin
- Around the hips
- In the lower back
- Inside the vagina
- Around the vulva
- In the perineum
- Around the rectum
- During urination or bowel movements
- During sexual intercourse
The location alone does not necessarily identify the cause.
For example, pain in the lower right abdomen may originate from:
- Appendix
- Right ovary
- Right fallopian tube
- Urinary tract
- Small bowel
- Abdominal wall
Similarly, pain in the lower back or pelvis can sometimes originate from the kidneys, ureters, spine, muscles, or pelvic organs.
2. Acute vs Chronic Pelvic Pain
One of the first questions in evaluating pelvic pain is:
How long has the pain been present?
Acute pelvic pain
Acute pelvic pain is generally considered intense, noncyclic pelvic or lower abdominal pain lasting less than three months. The causes range from benign conditions to life-threatening emergencies.
Important causes include:
- Ectopic pregnancy
- Ovarian torsion
- Ruptured ovarian cyst
- Pelvic inflammatory disease
- Appendicitis
- Kidney stones
- Urinary infection
- Gastrointestinal disease
Chronic pelvic pain
ACOG defines chronic pelvic pain as pain in the pelvic area lasting six months or longer. It may be constant or intermittent and may occur in relation to menstruation, urination, bowel movements, sexual activity, eating, exercise, or other activities.
Chronic pelvic pain may result from:
- Endometriosis
- Adenomyosis
- Irritable bowel syndrome
- Interstitial cystitis/bladder pain syndrome
- Pelvic-floor dysfunction
- Nerve-related pain
- Musculoskeletal problems
- Chronic pelvic inflammatory disease
- Adhesions
- Vulvar disorders
- Multiple overlapping conditions
Sometimes no single structural abnormality completely explains chronic pain. This does not mean the pain is imaginary. Long-lasting pain can involve changes in how the nervous system processes pain signals.
3. Why Pelvic Pain Can Be Difficult to Diagnose
The pelvis is a compact anatomical region containing multiple systems.
It includes:
Reproductive structures
- Uterus
- Cervix
- Ovaries
- Fallopian tubes
- Vagina
- Vulva
Urinary structures
- Bladder
- Distal ureters
- Urethra
Gastrointestinal structures
- Rectum
- Sigmoid colon
- Small bowel
- Appendix
Musculoskeletal structures
- Pelvic bones
- Hip joints
- Abdominal muscles
- Pelvic-floor muscles
- Ligaments
Nervous structures
- Peripheral nerves
- Pelvic autonomic nerves
- Sacral nerve roots
Because these structures are close together, symptoms may overlap.
A patient with ovarian disease may experience back pain.
A patient with bowel disease may experience pelvic pain.
A patient with a urinary problem may experience groin or lower abdominal pain.
This anatomical overlap makes a structured evaluation essential.
4. Common Causes of Pelvic Pain
The causes can be broadly classified into:
- Gynecological
- Pregnancy-related
- Urinary
- Gastrointestinal
- Musculoskeletal
- Neurological
- Psychological and pain-processing factors
- Malignancy
- Postoperative or post-traumatic causes
More than one category can apply to the same patient.
5. Menstrual Cramps — Dysmenorrhea
Dysmenorrhea is painful menstruation.
It is one of the most common causes of pelvic pain in menstruating individuals.
Primary dysmenorrhea occurs without an underlying pelvic disease and is associated with increased prostaglandin activity during menstruation.
Symptoms can include:
- Cramping lower abdominal pain
- Lower back pain
- Nausea
- Headache
- Diarrhea
- Fatigue
Pain typically begins around the onset of menstruation.
However, severe or progressively worsening menstrual pain should not automatically be dismissed as "normal."
It may indicate conditions such as:
- Endometriosis
- Adenomyosis
- Fibroids
- Pelvic inflammatory disease
6. Endometriosis
Endometriosis is an important cause of chronic and cyclical pelvic pain.
It occurs when tissue resembling the endometrium grows outside the uterine cavity.
Common locations include:
- Ovaries
- Pelvic peritoneum
- Uterosacral ligaments
- Rectovaginal region
- Bowel
- Bladder
Common symptoms include:
- Severe menstrual pain
- Chronic pelvic pain
- Deep pain during or after intercourse
- Painful bowel movements
- Cyclical bowel symptoms
- Cyclical urinary symptoms
- Infertility
NICE recommends considering endometriosis in patients presenting with chronic pelvic pain, significant period-related pain, deep dyspareunia, cyclical bowel or urinary symptoms, or infertility associated with these symptoms.
7. Adenomyosis
Adenomyosis occurs when endometrial-type tissue grows into the muscular wall of the uterus.
It may cause:
- Painful periods
- Heavy menstrual bleeding
- Pelvic pressure
- Enlarged uterus
- Chronic pelvic pain
Adenomyosis may coexist with endometriosis, making diagnosis more challenging.
Ultrasound and, in selected cases, MRI can help evaluate suspected adenomyosis.
8. Uterine Fibroids
Uterine fibroids are benign tumors arising from uterine smooth muscle.
They may be asymptomatic or cause:
- Heavy menstrual bleeding
- Pelvic pressure
- Pelvic pain
- Lower back pain
- Urinary frequency
- Constipation
- Abdominal enlargement
Pain can occur when a fibroid undergoes degeneration or when a large fibroid causes pressure on surrounding organs.
9. Ovarian Cysts
Ovarian cysts are common and many are functional and resolve spontaneously.
However, a cyst can cause pelvic pain if it:
- Becomes large
- Bleeds
- Ruptures
- Becomes infected
- Causes ovarian torsion
Pain may be unilateral.
A ruptured cyst can produce sudden pain, sometimes with internal bleeding.
The severity depends on the cyst and the amount of bleeding.
10. Ovarian Torsion
Ovarian torsion is an important gynecological emergency.
It occurs when the ovary rotates around its supporting structures, potentially compromising:
- Venous drainage
- Arterial blood flow
It commonly causes:
- Sudden severe unilateral pelvic pain
- Nausea
- Vomiting
- Adnexal tenderness
Torsion can threaten ovarian viability and fertility.
It requires urgent medical and gynecological assessment.
Ultrasound with Doppler is commonly used during evaluation, but imaging cannot always definitively exclude torsion.
Clinical suspicion remains important.
11. Ectopic Pregnancy
Ectopic pregnancy occurs when an embryo implants outside the normal uterine cavity, most commonly within a fallopian tube.
It is one of the most important causes of acute pelvic pain in a person who could be pregnant.
Possible symptoms include:
- Lower abdominal or pelvic pain
- Vaginal bleeding
- Missed menstrual period
- Shoulder-tip pain in cases of intraperitoneal bleeding
- Dizziness
- Fainting
If rupture occurs, severe internal bleeding can cause:
- Hypotension
- Tachycardia
- Collapse
- Shock
- Death if untreated
For reproductive-age patients with acute pelvic pain, pregnancy testing is an important early step.
12. Pelvic Inflammatory Disease
Pelvic inflammatory disease, or PID, is an infection and inflammatory disorder involving the upper female genital tract.
It can involve:
- Endometrium
- Fallopian tubes
- Ovaries
- Pelvic peritoneum
PID may be associated with sexually transmitted organisms such as:
- Chlamydia trachomatis
- Neisseria gonorrhoeae
However, PID is often polymicrobial, and vaginal flora and anaerobic organisms can also contribute.
Symptoms can include:
- Lower abdominal pain
- Pelvic pain
- Abnormal vaginal discharge
- Abnormal bleeding
- Pain during intercourse
- Fever
- Dysuria
Importantly, PID can be mild or even asymptomatic.
13. Why PID Matters
Untreated PID can cause long-term complications.
These may include:
- Infertility
- Ectopic pregnancy
- Chronic pelvic pain
- Tubo-ovarian abscess
- Adhesions
Because the consequences can be significant, CDC guidance recommends maintaining a relatively low threshold for considering PID in sexually active patients at risk for STIs who have pelvic or lower abdominal pain and appropriate examination findings.
14. Tubo-Ovarian Abscess
A tubo-ovarian abscess is a severe complication of pelvic infection.
It involves an inflammatory mass containing pus around the fallopian tube and ovary.
Patients may develop:
- Fever
- Severe pelvic pain
- Pelvic tenderness
- Abnormal vaginal discharge
- Nausea
- Vomiting
- Systemic illness
A tubo-ovarian abscess can become life-threatening if it ruptures.
Hospitalization and intravenous antimicrobial therapy may be necessary, with drainage or surgery in selected cases.
15. Urinary Tract Infection
A urinary tract infection can cause pelvic or suprapubic discomfort.
Common symptoms include:
- Burning urination
- Urinary frequency
- Urgency
- Suprapubic pain
- Cloudy or abnormal-smelling urine
If infection spreads to the kidneys, symptoms may include:
- Fever
- Chills
- Flank pain
- Nausea
- Vomiting
This distinction helps differentiate cystitis from pyelonephritis.
16. Kidney and Ureteric Stones
Urinary stones can cause severe pain when they move through the urinary tract.
The pain may begin in:
- Flank
- Back
and radiate toward:
- Lower abdomen
- Groin
- Genitals
Associated symptoms can include:
- Hematuria
- Nausea
- Vomiting
- Urinary urgency
A stone accompanied by fever or systemic illness is particularly concerning because infection and obstruction together can constitute a urological emergency.
17. Interstitial Cystitis / Bladder Pain Syndrome
Bladder pain syndrome is a chronic condition involving bladder-related pain or pressure often accompanied by urinary symptoms.
Patients may experience:
- Pelvic pressure
- Suprapubic pain
- Urinary frequency
- Urgency
- Pain that changes with bladder filling or emptying
The diagnosis is generally considered after other causes, particularly infection, have been evaluated.
It can overlap with other chronic pelvic pain conditions.
18. Appendicitis
Appendicitis is an important non-gynecological cause of pelvic pain.
Although classic appendicitis begins around the umbilicus and moves to the right lower quadrant, the location can vary.
A pelvic appendix can cause:
- Pelvic pain
- Rectal discomfort
- Urinary symptoms
- Diarrhea
Associated features may include:
- Fever
- Nausea
- Vomiting
- Loss of appetite
Because appendicitis can resemble gynecological disease, it should remain in the differential diagnosis.
19. Irritable Bowel Syndrome
Irritable bowel syndrome can produce chronic or recurrent abdominal and pelvic discomfort.
Symptoms may include:
- Abdominal pain
- Bloating
- Constipation
- Diarrhea
- Alternating bowel habits
Pain may improve or change after bowel movements.
IBS is a disorder of gut-brain interaction and may coexist with other chronic pelvic pain conditions.
20. Inflammatory Bowel Disease
Crohn disease and ulcerative colitis can produce abdominal and pelvic discomfort.
Additional symptoms may include:
- Chronic diarrhea
- Blood in stool
- Weight loss
- Fatigue
- Fever
- Rectal pain
Inflammatory bowel disease should be considered when pelvic pain occurs with persistent gastrointestinal symptoms or systemic signs.
21. Constipation
Constipation is a simple but frequently overlooked cause of pelvic discomfort.
Accumulated stool can produce:
- Lower abdominal pressure
- Pelvic pressure
- Bloating
- Rectal discomfort
- Pain during bowel movements
Severe constipation can occasionally produce substantial pain and urinary symptoms because of pressure on neighboring organs.
22. Pelvic Floor Dysfunction
The pelvic floor consists of muscles and connective tissues that support pelvic organs and contribute to:
- Urination
- Defecation
- Sexual function
- Core stability
Pelvic-floor muscles may become:
- Weak
- Overactive
- Tight
- Painful
- Poorly coordinated
Overactive pelvic-floor muscles can produce chronic pelvic pain, pain during intercourse, urinary symptoms, and bowel symptoms.
Pelvic-floor physical therapy is an important treatment option for selected patients with chronic pelvic pain.
23. Musculoskeletal Causes
Pelvic pain can arise from:
- Hip problems
- Sacroiliac joint dysfunction
- Lumbar spine disease
- Muscle strain
- Tendinopathy
- Abdominal wall pain
- Hernias
A detailed musculoskeletal examination can be particularly helpful when pelvic imaging is normal.
Pain associated with:
- Movement
- Exercise
- Lifting
- Specific postures
may suggest a musculoskeletal contribution.
24. Hernias
Inguinal and femoral hernias can produce:
- Groin pain
- Lower abdominal discomfort
- Pelvic pressure
- Pain during coughing or lifting
A visible or palpable bulge may be present.
A painful, irreducible hernia accompanied by vomiting or bowel obstruction symptoms can represent a surgical emergency.
25. Nerve-Related Pelvic Pain
Nerve irritation or entrapment can produce chronic pelvic pain.
The pain may be:
- Burning
- Electric
- Shooting
- Tingling
- Numb
- Triggered by sitting
Possible nerves involved include branches of the pudendal and lumbosacral plexus.
Neuropathic pelvic pain can be difficult to diagnose because standard imaging may appear normal.
26. Pelvic Adhesions
Adhesions are bands of scar tissue that can develop after:
- Abdominal surgery
- Pelvic surgery
- Infection
- Endometriosis
- Inflammation
They may cause chronic pain or contribute to bowel obstruction.
However, the presence of adhesions on imaging or laparoscopy does not always prove that they are the source of pain.
27. Pelvic Pain After Surgery
Pelvic pain can persist after:
- Cesarean delivery
- Hysterectomy
- Ovarian surgery
- Hernia repair
- Bowel surgery
- Other pelvic procedures
Possible causes include:
- Scar tissue
- Nerve injury
- Pelvic-floor dysfunction
- Infection
- Recurrent disease
- Central sensitization
Persistent postoperative pain should be evaluated rather than automatically attributed to the surgical scar.
28. Chronic Pelvic Pain and the Nervous System
Pain is not simply a measurement of tissue damage.
When pain continues for a long time, the nervous system can become increasingly sensitive to signals.
This phenomenon is sometimes described as central sensitization or altered pain processing.
Consequently, the severity of chronic pain may not correspond directly to what can be seen on imaging.
This is one reason why a patient can experience genuine severe pain even when scans show little structural abnormality.
ACOG emphasizes that chronic pelvic pain can sometimes persist through changes in the way the brain and nerves process pain signals, and treatment may still help even when a single cause is not identified.
29. Psychological Factors and Pelvic Pain
Psychological factors can influence chronic pain, but this should not be interpreted as meaning that the pain is "all in the patient's head."
Stress, anxiety, depression, trauma, and sleep disturbance can amplify pain perception and interfere with recovery.
ACOG notes an association between chronic pelvic pain and previous physical, emotional, or sexual trauma, while emphasizing that physical causes still need to be considered.
A comprehensive approach may therefore address:
- Physical disease
- Pain processing
- Sleep
- Stress
- Emotional health
- Sexual health
- Physical function
30. Pelvic Pain During Sexual Intercourse
Pain during sexual intercourse is called dyspareunia.
It may be:
- Superficial
- Deep
- Positional
- Cyclical
Possible causes include:
- Endometriosis
- Pelvic inflammatory disease
- Vaginal dryness
- Menopause-related tissue changes
- Pelvic-floor muscle dysfunction
- Vulvodynia
- Ovarian cysts
- Fibroids
- Trauma
- Infection
Pain during sex should not simply be accepted as unavoidable.
A clinician can investigate potential causes and identify appropriate treatment.
31. Pelvic Pain During Urination
Pain associated with urination can suggest:
- Urinary tract infection
- Bladder pain syndrome
- Kidney stone
- Urethral disorders
- Pelvic inflammatory disease
- Endometriosis involving the urinary tract
Cyclical urinary pain or hematuria around menstruation may raise suspicion for urinary tract endometriosis. NICE specifically identifies cyclical urinary symptoms, including painful urination or hematuria, as possible features of endometriosis.
32. Pelvic Pain During Bowel Movements
Pain with defecation can occur with:
- Constipation
- Hemorrhoids
- Anal fissure
- IBS
- Inflammatory bowel disease
- Endometriosis
- Pelvic-floor dysfunction
- Rectal disease
Painful bowel movements that consistently worsen around menstruation are particularly important because they may suggest endometriosis.
33. Pelvic Pain and Menopause
After menopause, pelvic pain requires careful evaluation.
Potential causes include:
- Vaginal or vulvar atrophy
- Urinary disorders
- Pelvic-floor dysfunction
- Fibroids
- Ovarian pathology
- Endometriosis
- Malignancy
New pelvic pain accompanied by postmenopausal bleeding deserves prompt medical evaluation.
The risk of certain gynecological malignancies increases with age, so persistent or unexplained symptoms should not be ignored.
34. Pelvic Pain in Adolescents
Adolescents can develop many of the same causes of pelvic pain as adults.
Important considerations include:
- Dysmenorrhea
- Endometriosis
- Ovarian cysts
- Ovarian torsion
- PID
- Appendicitis
- Urinary infection
- Pregnancy-related conditions when relevant
Congenital abnormalities such as an imperforate hymen may also cause pain and menstrual obstruction.
Ovarian torsion can occur at any age and should not be overlooked in adolescents.
35. Pelvic Pain During Pregnancy
Pelvic pain during pregnancy can have both benign and serious causes.
Possible causes include:
- Normal ligament stretching
- Constipation
- Urinary infection
- Round ligament pain
- Ectopic pregnancy in early pregnancy
- Miscarriage
- Ovarian torsion
- Appendicitis
- Placental complications later in pregnancy
- Preterm labor
Because pregnancy changes the differential diagnosis and imaging choices, new significant pelvic pain during pregnancy should be assessed by a healthcare professional.
36. Pelvic Pain After Childbirth
Postpartum pelvic pain can occur because of:
- Tissue injury
- Perineal trauma
- Cesarean incision
- Pelvic-floor muscle injury
- Uterine involution
- Infection
- Urinary problems
- Hematoma
- Musculoskeletal strain
Severe postpartum pelvic or abdominal pain accompanied by:
- Fever
- Heavy bleeding
- Foul-smelling discharge
- Fainting
- Shortness of breath
requires urgent evaluation.
37. Pelvic Pain in Men
Although pelvic pain is often discussed in relation to gynecological disease, men can experience significant pelvic pain.
Common causes include:
- Prostatitis
- Chronic pelvic pain syndrome
- Urinary tract infection
- Kidney or ureteric stones
- Benign prostatic enlargement with complications
- Inguinal hernia
- Pelvic-floor dysfunction
- Gastrointestinal disease
- Musculoskeletal disorders
38. Prostatitis
Prostatitis refers to inflammation or infection involving the prostate.
Acute bacterial prostatitis may cause:
- Pelvic pain
- Perineal pain
- Fever
- Chills
- Dysuria
- Urinary frequency
- Difficulty urinating
Chronic prostatitis/chronic pelvic pain syndrome may produce:
- Perineal discomfort
- Pelvic pressure
- Pain with ejaculation
- Urinary symptoms
- Chronic or intermittent pain
The evaluation differs depending on whether bacterial infection is suspected.
39. Acute Pelvic Pain: The First Question
When a patient presents with acute pelvic pain, the first priority is not to determine the most common cause.
The first priority is:
Could this be an emergency?
Important emergencies include:
- Ectopic pregnancy
- Ovarian torsion
- Ruptured ectopic pregnancy
- Significant internal bleeding
- Severe PID or tubo-ovarian abscess
- Appendicitis
- Bowel obstruction
- Strangulated hernia
- Obstructed infected urinary tract
40. Red-Flag Symptoms
Seek urgent medical attention for pelvic pain associated with:
- Fainting
- Severe dizziness
- Heavy vaginal bleeding
- Pregnancy or possible pregnancy
- Sudden severe unilateral pain
- High fever
- Repeated vomiting
- Abdominal rigidity
- Severe weakness
- Low blood pressure
- Rapid heartbeat
- Confusion
- Difficulty breathing
- Inability to urinate
- Blood in urine with severe pain
- Severe pain with a known kidney stone
- Rapidly worsening symptoms
These symptoms can indicate a medical or surgical emergency.
41. History Taking
A detailed history is one of the most valuable diagnostic tools.
The clinician should ask:
When did the pain begin?
Sudden onset suggests different conditions than gradual onset.
Where is the pain?
- Right
- Left
- Central
- Suprapubic
- Deep pelvic
- Groin
- Back
What does it feel like?
- Sharp
- Cramping
- Burning
- Pressure
- Aching
- Stabbing
- Colicky
Does it radiate?
For example:
Flank → groin
may suggest ureteric stone.
What makes it worse?
- Movement
- Eating
- Urination
- Defecation
- Sexual intercourse
- Menstruation
What makes it better?
This can also provide useful clues.
42. Menstrual and Reproductive History
For patients who menstruate, clinicians may ask about:
- Last menstrual period
- Cycle regularity
- Duration of bleeding
- Amount of bleeding
- Menstrual pain
- Mid-cycle pain
- Previous pregnancies
- Miscarriages
- Ectopic pregnancy
- Infertility
- Contraception
The relationship between pain and menstruation can be particularly informative.
43. Sexual History
When appropriate, sexual history should include:
- New sexual partners
- Number of partners
- Condom use
- Previous STIs
- Previous PID
- Pain during intercourse
- Abnormal discharge
- Postcoital bleeding
This information helps identify conditions such as PID and other sexually transmitted infections.
44. Urinary History
Ask about:
- Dysuria
- Frequency
- Urgency
- Hematuria
- Incomplete emptying
- Urinary retention
- Flank pain
These symptoms may suggest UTI, kidney stones, bladder pain syndrome, or other urinary conditions.
45. Gastrointestinal History
Ask about:
- Constipation
- Diarrhea
- Blood in stool
- Bloating
- Nausea
- Vomiting
- Weight loss
- Change in bowel habits
- Pain related to meals
- Pain during bowel movements
This can help distinguish gastrointestinal from gynecological causes.
46. Physical Examination
A physical examination may include:
- Vital signs
- Abdominal examination
- Pelvic examination when appropriate
- Musculoskeletal examination
- Neurological assessment
- Hernia examination
The examination should be performed respectfully and with attention to patient comfort and consent.
47. Abdominal Examination
The clinician looks for:
- Tenderness
- Guarding
- Rebound tenderness
- Distension
- Masses
- Hernias
The location of tenderness can provide important clues.
For example, right lower quadrant tenderness may raise suspicion for appendicitis, but ovarian or urinary pathology can produce similar findings.
48. Pelvic Examination
When clinically appropriate, pelvic examination may evaluate:
- Vaginal discharge
- Cervical abnormalities
- Cervical motion tenderness
- Uterine tenderness
- Adnexal tenderness
- Pelvic masses
- Pelvic-floor tenderness
Cervical motion, uterine, or adnexal tenderness can support consideration of PID in the appropriate clinical setting.
49. Pregnancy Testing
For patients who are sexually active and could become pregnant, a pregnancy test is an important early investigation when acute pelvic pain is present.
This is because pregnancy fundamentally changes the differential diagnosis.
A positive pregnancy test combined with pelvic pain and/or bleeding requires evaluation for:
- Normal intrauterine pregnancy
- Miscarriage
- Ectopic pregnancy
50. Urinalysis
Urinalysis can help identify:
- UTI
- Hematuria
- Kidney stone clues
- Other urinary abnormalities
It can also help distinguish urinary disease from gynecological disease.
51. STI Testing
Depending on the presentation, testing may include:
- Chlamydia
- Gonorrhea
- HIV
- Syphilis
- Other infections
The exact testing strategy depends on symptoms, risk factors, local guidelines, and clinical setting.
CDC guidance recommends testing women diagnosed with PID for gonorrhea, chlamydia, HIV, and syphilis.
52. Blood Tests
Depending on the suspected cause, laboratory testing may include:
- Complete blood count
- C-reactive protein
- ESR
- Electrolytes
- Kidney function
- Liver tests
- Blood cultures
- Pregnancy hormone testing
Blood tests can help identify:
- Infection
- Inflammation
- Anemia
- Bleeding
- Organ dysfunction
They usually cannot identify the cause by themselves.
53. Ultrasound
Ultrasound is an important imaging modality for pelvic pain.
In patients with suspected gynecological pathology, transvaginal ultrasonography is commonly the initial imaging test in nonpregnant patients, because it provides useful pelvic detail without radiation.
It can help identify:
- Ovarian cysts
- Fibroids
- Adenomyosis
- Adnexal masses
- Ectopic pregnancy
- Free pelvic fluid
- Some tubo-ovarian abscesses
- Features suggestive of torsion
54. CT Scan
CT may be preferred when a gastrointestinal or other abdominal cause is suspected.
It can help diagnose:
- Appendicitis
- Diverticulitis
- Bowel obstruction
- Urinary stones
- Abscesses
- Other abdominal pathology
The choice of imaging depends on age, pregnancy status, suspected diagnosis, renal function, and radiation considerations.
55. MRI
MRI provides excellent soft-tissue detail without ionizing radiation.
It can be useful when:
- Ultrasound is inconclusive
- Deep endometriosis is suspected
- Complex pelvic masses need characterization
- Certain pregnancy-related abdominal diagnoses require additional imaging
MRI is usually not the first test for every patient with pelvic pain.
56. Laparoscopy
Laparoscopy is a minimally invasive surgical procedure that allows direct visualization of the pelvic organs.
It may be used when:
- Endometriosis is suspected
- A surgical condition is suspected
- Imaging is inconclusive
- Treatment is required at the same time
However, surgery is not automatically appropriate for every patient with chronic pelvic pain.
57. Chronic Pelvic Pain Requires a Different Approach
Chronic pelvic pain is often more complicated than acute pain.
A patient may have:
- Endometriosis
- IBS
- Bladder pain syndrome
- Pelvic-floor dysfunction
- Nerve pain
- Musculoskeletal disease
at the same time.
ACOG emphasizes that chronic pelvic pain often benefits from multidisciplinary management, potentially involving gynecology, gastroenterology, urology, pelvic-floor physical therapy, pain specialists, and mental-health professionals.
58. The Pain Journal
A pain diary can be extremely useful.
Record:
- Date
- Time
- Location
- Severity
- Menstrual cycle day
- Food intake
- Bowel movements
- Urination
- Sexual activity
- Physical activity
- Medications
- What relieved the pain
- What worsened the pain
Patterns may reveal a connection that is difficult to recognize during a single clinic visit.
ACOG specifically recommends recording the timing, characteristics, triggers, severity, and associated activities in a chronic pelvic pain journal.
59. Treatment of Pelvic Pain
Treatment depends entirely on the cause.
There is no single medication that treats every type of pelvic pain.
Treatment may include:
- Pain medication
- Antibiotics
- Hormonal therapy
- Physical therapy
- Lifestyle changes
- Treatment of urinary or gastrointestinal disease
- Neuropathic pain medication
- Psychological therapies
- Interventional procedures
- Surgery
The best treatment is cause-directed whenever a cause can be identified.
60. Pain Relief
For selected patients, pain-relieving medications may include:
- Paracetamol/acetaminophen
- NSAIDs
NSAIDs can be particularly helpful for inflammatory and menstrual pain.
However, they may not be appropriate for everyone, particularly people with:
- Kidney disease
- Stomach ulcers
- Certain cardiovascular conditions
- Anticoagulant therapy
- Specific medication interactions
Medication should therefore be individualized.
61. Antibiotics
Antibiotics are appropriate when bacterial infection is the cause or strongly suspected.
Examples include:
- PID
- Certain urinary tract infections
- Some postoperative infections
- Certain pelvic abscesses
Antibiotics should not be used routinely for unexplained chronic pelvic pain without evidence of bacterial infection.
In PID, early appropriate treatment is important because delayed treatment can contribute to reproductive complications.
62. Hormonal Treatment
Hormonal therapy may help certain causes of pelvic pain, particularly:
- Endometriosis
- Dysmenorrhea
- Some fibroid-related symptoms
- Adenomyosis
Options may include:
- Combined hormonal contraceptives
- Progestin therapy
- Hormonal IUD
- Other hormone-modulating treatments
The appropriate choice depends on the diagnosis, reproductive goals, contraindications, and patient preference.
63. Pelvic-Floor Physical Therapy
Pelvic-floor physical therapy can be particularly useful when pain involves muscle tension or myofascial dysfunction.
Therapy may include:
- Muscle relaxation
- Stretching
- Trigger-point treatment
- Postural training
- Breathing exercises
- Biofeedback
- Movement retraining
ACOG identifies pelvic-floor physical therapy as one of the treatment options for chronic pelvic pain.
64. Cognitive Behavioral Therapy
Cognitive behavioral therapy, or CBT, does not mean that pelvic pain is psychological.
Instead, CBT can help patients develop strategies for:
- Coping with persistent pain
- Reducing pain-related distress
- Improving sleep
- Improving function
- Managing anxiety associated with chronic symptoms
ACOG lists CBT among approaches that may help patients with chronic pelvic pain.
65. Lifestyle Measures
For chronic pelvic pain, supportive lifestyle measures may include:
- Regular physical activity
- Healthy nutrition
- Adequate sleep
- Stress management
- Good posture
- Avoidance of known triggers
- Maintaining social connections
These strategies generally work best as part of a broader treatment plan rather than as substitutes for medical treatment.
66. Surgery
Surgery may be appropriate for selected conditions.
Examples include:
- Ectopic pregnancy
- Ovarian torsion
- Certain ovarian cysts
- Large symptomatic fibroids
- Certain endometriosis lesions
- Appendicitis
- Hernia
- Abscess requiring drainage
- Other structural abnormalities
However, surgery does not guarantee resolution of chronic pain.
This is especially important when the pain is multifactorial or involves altered pain processing.
67. Treating Endometriosis-Related Pain
Management may include:
- NSAIDs
- Hormonal suppression
- Progestins
- Combined hormonal contraceptives
- GnRH-related therapies
- Surgery in selected cases
Treatment depends on:
- Pain severity
- Disease extent
- Fertility plans
- Previous treatment
- Patient preference
NICE recommends discussing the benefits and risks of medical and surgical options according to symptoms and reproductive goals.
68. Treating PID
PID requires appropriate antimicrobial therapy directed against likely pathogens.
Treatment should be initiated promptly when clinical suspicion is sufficient because delayed treatment can contribute to long-term reproductive complications.
Hospitalization may be considered when:
- A surgical emergency cannot be excluded
- Tubo-ovarian abscess is present
- The patient is pregnant
- Severe illness is present
- Vomiting prevents oral therapy
- Outpatient treatment cannot be followed
- There is no clinical improvement
These principles are reflected in current CDC guidance.
69. Treating Ovarian Torsion
Ovarian torsion is generally treated as a surgical emergency.
The goal is to restore blood flow and preserve ovarian tissue when possible.
Treatment may involve:
- Detorsion
- Removal of a causative cyst or mass when appropriate
- Ovarian conservation when feasible
Prompt treatment is important because prolonged vascular compromise can result in tissue necrosis.
70. Treating Ectopic Pregnancy
Management depends on:
- Hemodynamic stability
- Pregnancy location
- Pregnancy hormone levels
- Size and features of the ectopic pregnancy
- Presence or absence of rupture
- Patient's fertility goals
- Availability of follow-up
Treatment may include:
- Expectant management in carefully selected cases
- Medication such as methotrexate in appropriate patients
- Surgery
A ruptured ectopic pregnancy with significant internal bleeding is an emergency requiring urgent surgical management.
71. Treating Chronic Pelvic Pain When No Single Cause Is Found
This can be one of the most difficult situations for patients.
The absence of a single identifiable lesion does not mean that treatment should stop.
A multidisciplinary approach may include:
- Pelvic-floor physical therapy
- Pain management
- Neuropathic pain medications
- CBT
- Hormonal treatment when appropriate
- Exercise
- Sleep improvement
- Management of bowel or bladder symptoms
ACOG emphasizes that chronic pelvic pain can be treated even when a specific cause is not identified.
72. Can Pelvic Pain Be Prevented?
Not every cause can be prevented.
However, several measures can reduce the risk of certain conditions.
These include:
- Practicing safer sex
- STI screening when appropriate
- Prompt treatment of urinary infections
- Managing constipation
- Maintaining healthy physical activity
- Avoiding unnecessary pelvic procedures
- Seeking evaluation for recurrent pelvic pain
- Managing chronic diseases
- Following recommended gynecological screening
73. Preventing Pelvic Inflammatory Disease
Because some PID cases are related to sexually transmitted infections, prevention strategies include:
- Condom use
- STI testing
- Prompt treatment of diagnosed infections
- Appropriate partner evaluation and treatment
- Avoiding sexual contact until treatment is complete when an STI has been diagnosed
CDC guidance emphasizes screening and treatment for chlamydia and gonorrhea as strategies that reduce PID risk.
74. Pelvic Pain and Fertility
Some causes of pelvic pain can affect fertility.
Important examples include:
- Endometriosis
- PID
- Tubal damage
- Severe pelvic adhesions
- Certain ovarian disorders
PID can damage the fallopian tubes and increase the risk of infertility and ectopic pregnancy.
Patients with pelvic pain and difficulty becoming pregnant may therefore require specialist evaluation.
75. Pelvic Pain and Sexual Health
Chronic pain can affect:
- Sexual desire
- Arousal
- Comfort during intercourse
- Relationships
- Self-esteem
Pain during sex can also create a cycle of:
Pain → muscle tension → fear of pain → more muscle tension → more pain
Treatment may therefore require attention to both physical and sexual-health factors.
Sex therapy and pelvic-floor physical therapy may be useful for selected patients.
76. When Should You See a Doctor?
Medical evaluation is appropriate when pelvic pain:
- Persists
- Repeatedly returns
- Interferes with daily activities
- Affects sexual activity
- Is associated with abnormal bleeding
- Occurs with urinary symptoms
- Occurs with bowel changes
- Is associated with infertility
- Is progressively worsening
- Requires frequent pain medication
Even when the pain is not an emergency, recurrent symptoms deserve evaluation.
77. When Should You Go to the Emergency Department?
Immediate medical assessment is appropriate for:
- Sudden severe pelvic pain
- Severe pain during possible pregnancy
- Fainting or collapse
- Heavy vaginal bleeding
- Severe abdominal tenderness
- Fever with severe pelvic pain
- Persistent vomiting
- Severe weakness
- Rapid heart rate
- Low blood pressure
- Confusion
- Difficulty breathing
These symptoms can indicate internal bleeding, infection, torsion, appendicitis, or another emergency.
78. A Practical Clinical Approach to Acute Pelvic Pain
A useful approach is:
Step 1 — Assess stability
Check:
- Blood pressure
- Pulse
- Respiratory rate
- Temperature
- Mental status
Step 2 — Consider pregnancy
Perform pregnancy testing when relevant.
Step 3 — Identify the organ system
Consider:
- Gynecological
- Urinary
- Gastrointestinal
- Musculoskeletal
Step 4 — Look for emergency diagnoses
Think about:
- Ectopic pregnancy
- Torsion
- Ruptured cyst
- Appendicitis
- Severe PID
- Obstruction
Step 5 — Perform targeted testing
Use:
- Urinalysis
- Pregnancy testing
- STI testing
- CBC
- Inflammatory markers
- Imaging when appropriate
Step 6 — Treat the underlying cause
Avoid treating pelvic pain as a diagnosis by itself.
79. A Practical Approach to Chronic Pelvic Pain
For chronic symptoms:
Step 1
Determine whether pain is cyclical.
Step 2
Ask whether it is related to:
- Menstruation
- Sex
- Urination
- Bowel movements
- Eating
- Physical activity
Step 3
Review previous diagnoses and surgeries.
Step 4
Evaluate gynecological, urinary, gastrointestinal, and musculoskeletal causes.
Step 5
Assess pelvic-floor function.
Step 6
Consider endometriosis and other chronic conditions.
Step 7
Use targeted imaging rather than indiscriminate testing.
Step 8
Develop a multidisciplinary treatment plan when appropriate.
80. Pelvic Pain: High-Yield Medical Student Points
Remember these principles:
Acute pelvic pain
Think:
Pregnancy → Gynecological → Urinary → Gastrointestinal → Musculoskeletal
Always consider emergencies
- Ectopic pregnancy
- Ovarian torsion
- Appendicitis
- Ruptured ovarian cyst
- Severe PID
Chronic pelvic pain
Think beyond gynecology:
- Endometriosis
- IBS
- Bladder pain syndrome
- Pelvic-floor dysfunction
- Neuropathic pain
- Musculoskeletal disease
Important investigation
Pregnancy test when pregnancy is possible.
Common initial imaging
Ultrasound, particularly when gynecological pathology is suspected.
Important concept
Normal imaging does not necessarily mean the patient's pain is not real.
81. Common Myths About Pelvic Pain
Myth 1: "Pelvic pain is always a gynecological problem."
False.
Urinary, gastrointestinal, musculoskeletal, neurological, and other conditions can cause pelvic pain.
Myth 2: "Painful periods are always normal."
Mild menstrual discomfort is common, but severe, worsening, or disabling pain can indicate endometriosis, adenomyosis, fibroids, or other disease.
Myth 3: "If an ultrasound is normal, nothing is wrong."
False.
Some causes of pelvic pain may not be visible on routine imaging.
Myth 4: "Chronic pelvic pain is psychological."
False.
Chronic pelvic pain is real and can result from multiple physical and neurological mechanisms.
Myth 5: "PID always causes obvious symptoms."
False.
PID can be subtle or asymptomatic.
Myth 6: "Pelvic pain during pregnancy can always be ignored."
False.
Some causes are benign, but ectopic pregnancy and other pregnancy-related emergencies must be considered.
82. Frequently Asked Questions
What is pelvic pain?
Pelvic pain is pain or discomfort perceived in the lower abdomen, pelvis, groin, or surrounding pelvic structures.
What is the most common cause of pelvic pain?
There is no single cause. The likely causes depend on age, sex, pregnancy status, duration, associated symptoms, and clinical findings.
What causes sudden pelvic pain?
Important causes include ovarian torsion, ruptured ovarian cyst, ectopic pregnancy, appendicitis, kidney stones, PID, and other acute abdominal or pelvic conditions.
Can pelvic pain be caused by an infection?
Yes. PID, urinary tract infections, pyelonephritis, and some pelvic abscesses can cause pelvic pain.
Can constipation cause pelvic pain?
Yes. Constipation can cause pressure and discomfort in the lower abdomen and pelvis.
Can kidney stones cause pelvic pain?
Yes. A ureteric stone can produce pain that travels from the flank toward the lower abdomen and groin.
Can endometriosis cause pelvic pain?
Yes. Chronic pelvic pain and severe period-related pain are important symptoms of endometriosis.
Can pelvic pain affect fertility?
Yes. Conditions such as PID and endometriosis can affect fertility.
Can pelvic pain occur without an identifiable cause?
Yes. Chronic pelvic pain can sometimes persist without one clearly identifiable structural cause, and treatment can still be beneficial.
What test is usually done first for pelvic pain?
The appropriate test depends on the patient. Pregnancy testing is important when pregnancy is possible, while ultrasound is commonly the initial imaging study when gynecological disease is suspected.
Is pelvic pain during periods normal?
Mild menstrual cramps can be normal. Severe, worsening, or disabling pain should be evaluated.
Can pelvic pain be caused by stress?
Stress can worsen pain perception and chronic pain, but persistent pelvic pain should still be evaluated for physical causes.
Can pelvic pain be caused by sexual intercourse?
Yes. Pain during or after intercourse can occur with endometriosis, PID, pelvic-floor dysfunction, vaginal dryness, ovarian disease, and other conditions.
Can pelvic pain be a sign of cancer?
It can, although many more common benign conditions cause pelvic pain. Persistent unexplained symptoms, particularly in older adults or when associated with abnormal bleeding, weight loss, or a pelvic mass, require medical evaluation.
When is pelvic pain an emergency?
Sudden severe pain, fainting, heavy bleeding, pregnancy-associated pain, high fever, severe vomiting, shock, or rapidly worsening symptoms should be treated as potential emergencies.
83. Final Takeaway
Pelvic pain is a symptom, not a diagnosis.
It can arise from virtually every major system in and around the pelvis, including the reproductive organs, urinary tract, bowel, pelvic-floor muscles, abdominal wall, nerves, and musculoskeletal structures.
Acute pelvic pain requires special attention because potentially life-threatening conditions can initially resemble relatively harmless disorders. In patients who could be pregnant, pregnancy testing is an important early step. Ectopic pregnancy, ovarian torsion, ruptured ovarian cyst, PID, appendicitis, and urinary obstruction should remain important considerations.
Chronic pelvic pain is different. It often develops from a combination of conditions and mechanisms rather than a single lesion. Endometriosis, adenomyosis, IBS, bladder pain syndrome, pelvic-floor dysfunction, neuropathic pain, and musculoskeletal disorders may overlap. ACOG emphasizes that chronic pelvic pain can be treated even when no single cause is found and that multidisciplinary care may be beneficial.
Some of the most important warning signs are:
Sudden severe pelvic pain
Pelvic pain with pregnancy or possible pregnancy
Heavy bleeding
Fainting or severe dizziness
High fever
Persistent vomiting
Severe abdominal tenderness
Rapid deterioration
These symptoms require urgent assessment.
For chronic pelvic pain, successful management often involves more than medication. Depending on the cause, treatment may include hormonal therapy, antibiotics, physical therapy, pain-management strategies, lifestyle changes, psychological therapies, procedures, or surgery.
The most important lesson is that pelvic pain should neither be ignored nor automatically attributed to one organ.
Find the cause, recognize the emergencies, treat the underlying condition, and remember that persistent pain deserves care even when the initial tests appear normal.
