Endometriosis is often the first diagnosis suggested for women with chronic pelvic pain — and for many, correctly. But pelvic pain has multiple other causes that should not be overlooked. If endometriosis has been ruled out and pain persists, the differential is wide.

Persistent pelvic pain not endometriosis — Causes of persistent pelvic pain beyond endometriosis
1. Adenomyosis
Endometrial tissue within the uterine wall causing painful periods and chronic pelvic pain. Often coexists with endometriosis. Diagnosed by MRI.
2. Pelvic congestion syndrome
Dilated pelvic veins causing dull, dragging pain that worsens with prolonged standing. Diagnosed by venography or MRI.
3. Adhesions from prior surgery
Scar tissue tethering pelvic organs. Common after Caesarean section, appendectomy, prior surgery for endometriosis.
4. Interstitial cystitis / painful bladder syndrome
Chronic bladder inflammation causing pain in lower abdomen and pelvis, worse with bladder filling. Diagnosed by cystoscopy.
5. Ovarian cysts (benign)
Functional cysts, dermoid cysts, endometriomas, hemorrhagic cysts. Usually evaluated by ultrasound.
6. Pelvic inflammatory disease (chronic)
Long-standing infection from past STI causes scarring and chronic pain. May need targeted antibiotics.
7. Irritable bowel syndrome / IBD
Bowel disorders can present as pelvic pain. Often confused with gynaecological causes.
8. Musculoskeletal pain
Pelvic floor muscle dysfunction, piriformis syndrome, sacroiliac joint dysfunction. Often missed by gynaecologists.
9. Nerve entrapment
Pudendal neuralgia, iliohypogastric nerve entrapment.
10. Ovarian or gynaecological cancer (rare)
Rarely presents purely as pain, but cannot be dismissed. Ultrasound and tumour markers help rule out.
Diagnostic approach
- Detailed pain history — onset, pattern, triggers, relieving factors
- Pelvic examination with attention to musculoskeletal trigger points
- Transvaginal ultrasound
- MRI pelvis (often the key investigation)
- Cystoscopy if bladder symptoms predominate
- Laparoscopy for diagnostic and therapeutic intervention
- Multidisciplinary review — gynaec, urology, gastroenterology, physiotherapy
Red flag symptoms
- Persistent pain combined with bloating, early satiety, or unintentional weight loss → urgent ovarian cancer evaluation
- Pelvic pain with abnormal bleeding → endometrial pathology assessment
- Sudden severe pain → rule out ovarian torsion, ruptured ectopic, abscess
- Pain with fever → infection workup

FAQs
My MRI showed endometriosis but treatment isn't helping. What now?
Coexisting causes (adenomyosis, IC, musculoskeletal) are very common. A second opinion focused on these may help.
Can pelvic pain be 'in my head'?
Chronic pelvic pain has psychological components in many women, but it is rarely purely psychological. Multimodal management (physical + psychological) is most effective.
Do I need a gynae-oncologist for this?
Not usually. A general gynaecologist evaluates first. If cancer is suspected, referral to gynae-onco is appropriate.
Should I have laparoscopy?
Diagnostic laparoscopy can confirm endometriosis or adhesions and treat them simultaneously. It is more invasive than imaging — used when imaging is inconclusive and pain is debilitating.
