Endometriosis and Pelvic Pain: You Do Not Have to Wait Years for a Plan

What endometriosis means

Endometriosis is a condition in which tissue similar to the lining of the uterus is found outside the uterus. It can cause painful periods, pelvic pain, pain during sex, and fertility problems. Symptoms vary, and a person's pain may affect school, work, sleep, relationships, and mental health. The symptoms deserve a clear assessment even when an earlier examination or scan was reassuring. PR26 PR27

Some pelvic pain comes from another source, such as the bladder, bowel, muscles, nerves, an infection, or an ovarian problem. More than one problem can occur at the same time. A careful evaluation should avoid two shortcuts: assuming that every pelvic symptom is endometriosis, and assuming that a normal scan means there is no important problem.

A meaningful change in 2026 guidance

ACOG's 2026 endometriosis guidance supports a presumptive clinical diagnosis based on the history, symptoms, and examination. Treatment can begin while imaging and further evaluation proceed. Patients do not have to undergo surgery before every initial treatment decision. The guidance applies to symptomatic adolescents as well as adults. PR26 PR27

This is useful when a person has recurring symptoms and has repeatedly been told to wait. It does not mean that every diagnosis can be made from a symptom checklist. The clinician still needs to consider other conditions, treatment risks, pregnancy goals, and the circumstances in which surgery may be helpful.

What to say at the appointment

Describe the effect on your life as well as the pain score. Examples include missing two school days each month, being unable to sit comfortably at work, avoiding sex because of pain, or feeling afraid of the next period. Record whether bowel or bladder symptoms change around menstruation. Bring names of past treatments, their duration, and what happened when you used them.

Ask the clinician to explain the working diagnosis. A working diagnosis is the best current explanation, with a plan to confirm, reconsider, or treat it. It should not become a permanent label that prevents reassessment when symptoms change.

What scans can and cannot show

Ultrasound can identify some ovarian endometriomas and deeper disease and can help find other pelvic problems. MRI may help with selected questions, especially the extent of deep disease. Normal imaging does not reliably exclude superficial endometriosis. The ESHRE guideline makes that limitation explicit. PR28

NICE recommends investigation, referral when needed, and initial treatment proceeding together. It also advises against using CA-125 to diagnose endometriosis. If symptoms persist despite treatment or imaging does not settle the question, specialist assessment may include discussion of laparoscopy. PR29

Before an internal scan or examination, ask what it is expected to show, what alternatives are reasonable, how discomfort will be addressed, and whether a support person or chaperone can be present. Consent should be ongoing; the patient should be able to pause the examination.

Treatment is based on the problem you most want to improve

Pain treatment can include appropriate anti-inflammatory medicines, hormonal suppression, or other approaches depending on pregnancy plans and contraindications. Hormonal methods may reduce symptoms by suppressing ovulation or menstrual activity. Some patients need surgery, particularly when symptoms persist, a concerning mass is present, or a specific anatomical problem needs treatment. These options require individual counseling. PR19 PR28

Some oral medicines change ovarian hormone signaling and have important bone, mood, and interaction warnings. Myfembree is approved for moderate to severe endometriosis pain in premenopausal women, with a 24-month treatment limit. It does not prevent pregnancy. Use effective nonhormonal contraception during treatment and for one week afterward; hormonal contraceptives should be stopped before starting under the prescriber's plan. It must not be used during pregnancy. PR25

If trying to become pregnant is the priority, say that at the start. Some medicines used to control endometriosis symptoms prevent ovulation while being taken. A plan focused on pain suppression and a plan focused on conception may therefore require different choices and different specialists.

Pelvic floor and pain rehabilitation can help

Pelvic muscles can become overactive or tender with chronic pain. Pelvic floor physical therapy may help selected patients, and care may also address sleep, movement, bowel symptoms, and pain coping. These measures can be used alongside treatment of an underlying condition. They should not be presented as proof that pain is imagined. ACOG describes chronic pelvic pain as a problem that may require several treatments and more than one member of the care team. PR56

Ask how progress will be measured. Better sleep, increased activity, less pain with daily tasks, and fewer missed days may be meaningful improvements even before every symptom resolves. If a treatment causes significant adverse effects or provides no benefit, the plan should be revisited.

When pain is an emergency

Sudden severe pain, fainting, repeated vomiting, fever with significant pelvic pain, or possible pregnancy with pain or bleeding needs urgent evaluation. A history of endometriosis does not protect someone from an ectopic pregnancy, ovarian torsion, appendicitis, or another acute problem. Do not automatically attribute a new emergency pattern to a chronic diagnosis. PR67

For persistent symptoms, ask for gynecology referral when pain remains disruptive, a mass or deep disease is suspected, fertility is affected, or the diagnosis is uncertain. Bowel, bladder, or nerve involvement may need a team with relevant experience.

Questions to bring: What else could explain my symptoms? Can we begin treatment while evaluation continues? Would specialist imaging help? What would surgery change? How does this plan fit my pregnancy goals? Do I need pelvic floor therapy or a fertility specialist? When will we reassess if I am still missing work or school?
