The short answer: if endometriosis has been ruled out but pain low in your tummy (pelvic pain) carries on, there are many other possible causes — the womb muscle (adenomyosis), swollen pelvic veins, scar tissue from past surgery, the bladder, the bowel, or the muscles and nerves of the pelvis. Most of these are not cancer, and many can be treated once they are found. Cancer is a rare cause, but pain that comes with bloating, feeling full quickly or weight loss should be checked.
In Hindi this is often searched as pet ke neeche dard (पेट के नीचे दर्द). Endometriosis is often the first diagnosis suggested for women with long-lasting (chronic) pelvic pain — and for many, correctly. But pelvic pain has other causes that should not be overlooked, and the list below covers the main ones.

Causes of persistent pelvic pain beyond endometriosis
1. Adenomyosis
Tissue like the womb lining growing into the womb muscle, causing painful, often heavy periods and long-lasting pelvic pain. Often occurs together with endometriosis. Usually seen on ultrasound or MRI.
2. Pelvic congestion syndrome
Swollen (dilated) veins in the pelvis causing a dull, dragging pain that gets worse after standing for a long time. Diagnosed with special imaging of the veins (venography) or MRI.
3. Adhesions from prior surgery
Bands of scar tissue that stick pelvic organs together. Common after a Caesarean section, appendix removal (appendectomy) or earlier surgery for endometriosis.
4. Interstitial cystitis / painful bladder syndrome
Long-lasting bladder irritation causing pain in the lower tummy and pelvis that gets worse as the bladder fills. A camera look inside the bladder (cystoscopy) may be used.
5. Ovarian cysts (benign)
Harmless fluid-filled sacs on the ovary — for example cysts that form during the monthly cycle (functional cysts), dermoid cysts, endometriosis cysts (endometriomas) or cysts with bleeding inside (haemorrhagic cysts). Usually checked with an ultrasound.
6. Pelvic inflammatory disease (chronic)
A past infection of the womb, tubes or ovaries, often from a sexually transmitted infection (STI), can leave scarring and long-lasting 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 causes pain on its own, but cannot be dismissed. A pelvic ultrasound and the CA-125 blood test (a tumour marker; most labs treat below 35 U/mL as normal) are the usual first tests.
Diagnostic approach
Tests are chosen step by step, not all at once, and depend on your symptoms. The assessment of persistent pelvic pain is explained in more detail on a separate page. In short:
- Detailed pain history — when it started, its pattern, what makes it worse or better
- Pelvic examination, including checking for tender spots in the pelvic muscles
- Internal (transvaginal) ultrasound
- MRI of the pelvis if the ultrasound is unclear
- A camera look inside the bladder (cystoscopy) if bladder symptoms are the main problem
- Keyhole surgery to look inside (laparoscopy) in selected women when tests are normal but pain continues — problems found can often be treated at the same time
- Multidisciplinary review — gynaec, urology, gastroenterology, physiotherapy
Red flag symptoms
- Pain with bloating, feeling full quickly or needing to pass urine urgently that is new and happens on most days (more than 12 times a month), or unexplained weight loss → see a gynaecologist soon; the first tests are a pelvic ultrasound and CA-125. Most women with these symptoms do not have ovarian cancer.
- Pelvic pain with abnormal bleeding, especially any bleeding after menopause → a check of the womb lining
- Sudden severe pain → get emergency care the same day; causes include a twisted ovary (torsion), a pregnancy outside the womb (ectopic pregnancy) or a pus collection (abscess)
- Pain with fever → see a doctor promptly to check for infection
If none of these apply, the cause is most often one of the non-cancer conditions above — including endometriosis as a possible cause of pain that was missed on earlier tests, since it often does not show on a routine scan.

FAQs
My MRI showed endometriosis but treatment isn't helping. What now?
Other causes alongside endometriosis — adenomyosis, bladder pain (interstitial cystitis) or muscle-related pain — 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.
My ultrasound is normal but I still have pelvic pain. What next?
A normal scan is reassuring about cysts and many other problems, but it does not mean the pain is imaginary. Endometriosis, scar tissue (adhesions), and muscle or nerve pain often do not show on a scan. Next steps may include an examination for tender pelvic muscles, an MRI, or — in selected women whose pain continues — a laparoscopy.
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.
