PART 1: INTRODUCTION TO PELVIC PAIN
1.1 Definition of Pelvic Pain
Pelvic pain refers to discomfort located in the lower abdomen or pelvis. It may arise from:
- Reproductive organs
- Urinary system
- Gastrointestinal tract
- Musculoskeletal structures
- Nerves or vascular structures
Pelvic pain can be:
- Acute (sudden onset, usually less than 3 months)
- Chronic (lasting more than 3–6 months)
1.2 Anatomy of the Pelvis
The pelvis is a complex anatomical region containing:
A. Bony Structures
- Ilium
- Ischium
- Pubis
- Sacrum
- Coccyx
B. Reproductive Organs
Female:
- Uterus
- Ovaries
- Fallopian tubes
- Cervix
- Vagina
Male:
- Prostate
- Seminal vesicles
- Vas deferens
C. Urinary Structures
- Urinary bladder
- Urethra
D. Gastrointestinal Structures
- Sigmoid colon
- Rectum
- Appendix
E. Neurovascular Supply
- Pudendal nerve
- Pelvic splanchnic nerves
- Internal iliac vessels
Because multiple organ systems lie within a confined space, pelvic pain often has overlapping causes.
1.3 Epidemiology
Pelvic pain is extremely common, especially among women.
- Up to 20–30% of women experience chronic pelvic pain at some point.
- It is one of the most common gynecological complaints.
- In emergency settings, acute pelvic pain is a frequent presentation.
In Pakistan and other developing countries, pelvic pain may be underreported due to:
- Cultural factors
- Limited access to healthcare
- Lack of awareness

PART 6: APPROACH TO HISTORY TAKING IN PELVIC PAIN
A detailed history is the most important step in diagnosing pelvic pain. In many cases, careful history alone can narrow the diagnosis significantly before investigations.
Pelvic pain assessment must be systematic, sensitive, and structured, especially in conservative societies such as Pakistan, where patients may hesitate to discuss reproductive or sexual symptoms openly.
6.1 Basic Patient Information
Always begin with:
- Age
- Marital status
- Occupation
- Parity (number of pregnancies)
- Last menstrual period (LMP)
- Contraceptive use
Age helps narrow differential diagnoses:
- Adolescents → dysmenorrhea, ovarian torsion
- Reproductive age → ectopic pregnancy, PID, endometriosis
- Postmenopausal → malignancy suspicion
6.2 Pain Analysis (SOCRATES Method)
Use structured pain assessment:
S – Site
- Unilateral or bilateral?
- Suprapubic, lower abdomen, deep pelvic?
O – Onset
- Sudden (torsion, rupture)?
- Gradual (endometriosis)?
C – Character
- Crampy → uterine
- Sharp → peritoneal irritation
- Burning → neuropathic
R – Radiation
- To back → dysmenorrhea
- To groin → ureteric stone
A – Associated Symptoms
- Fever
- Vaginal discharge
- Urinary symptoms
- Bowel changes
- Syncope
T – Timing
- Cyclical with menses?
- Constant?
- Worse at night?
E – Exacerbating/Relieving Factors
- Worse during intercourse → endometriosis
- Relieved after urination → interstitial cystitis
S – Severity
- Use pain scale (0–10)
6.3 Menstrual History

Pelvic pain is not merely a symptom but a complex neurobiological process involving peripheral nociceptors, spinal pathways, and central processing centers.
11.1 Pain Pathways in the Pelvis
A. Peripheral Nociceptors
Activated by:
- Inflammation
- Ischemia
- Tissue stretching
- Infection
Receptors transmit signals via:
- A-delta fibers (sharp pain)
