Persistent pelvic pain after endometriosis: beyond lesion removal to nervous-system factors and multidisciplinary care

Summary

Original publisher: The Conversation. Endometriosis affects about 1 in 10 women of reproductive age worldwide, and treatment with hormones or surgery can relieve symptoms for many but not all. This article explains that persistent pelvic pain after treatment can arise from several contributors beyond the visible lesions, including other conditions such as adenomyosis, pelvic floor dysfunction, bowel symptomatology, and changes in how the nervous system processes pain (central sensitisation). It highlights weak links between disease extent and pain severity and emphasizes that comprehensive, multidisciplinary care is often needed to address ongoing symptoms and preserve quality of life. A broader care approach may reduce pain and improve sexual function, though evidence remains uncertain and patient experiences must be taken seriously.

Overview

Endometriosis is a condition in which tissue similar to the lining of the uterus grows elsewhere in the body, commonly around pelvic organs. It affects about one in ten women of reproductive age worldwide. Treatments, including hormone medicines and surgery, can provide relief, but many patients continue to experience pelvic pain even after these interventions. The article notes that persistent pain can arise from several contributors beyond endometriosis itself, including residual disease, coexisting conditions such as adenomyosis, pelvic floor muscle tension, bowel dysfunction, and changes in how the nervous system processes pain. The complexity of chronic pelvic pain requires a nuanced approach that looks beyond the visible lesions and considers multiple pain generators and their interactions.

Endometriosis and treatment limitations

Treatments aim to reduce the activity of endometriosis lesions or remove disease areas, but they do not guarantee complete pain relief. Hormone therapies suppress the menstrual cycle or reduce oestrogen activity, which can alleviate endometriosis-related pain, yet other pain sources may remain untreated. Surgery can remove endometriosis, but disease can persist, recur, or be accompanied by pain from other origins such as the abdominal wall or bowel dysfunction. Adenomyosis, in which womb lining tissue grows into the muscular wall of the uterus, can coexist with endometriosis and may not be addressed by surgery that targets endometriosis outside the womb. When conventional treatments fail, hysterectomy can be considered, though pelvic pain may persist if other pain generators remain.

Central nervous system contributions to pain

A critical part of the discussion is how the nervous system can alter pain sensitivity. Central sensitisation describes a state in which the brain and spinal cord become more responsive to signals from the body, making normally non-painful stimuli painful and intensifying painful sensations. A study of 520 women with endometriosis found that at least a quarter had another long-term pain condition, illustrating how comorbid pain can perpetuate pain even after endometriosis treatment. In a study of 239 patients undergoing endometriosis surgery, higher scores on a central-sensitisation-related questionnaire were linked to worse pain after surgery, even after accounting for baseline pain. These findings support the idea that pain after treatment is multifactorial and can be influenced by changes in pain processing as well as remaining disease.

What comprehensive care looks like

Given the diverse contributors to persistent pelvic pain, a multidisciplinary approach is often recommended. This approach involves a gynecologist to assess endometriosis and related conditions, a pelvic health physiotherapist to evaluate pelvic floor and abdominal wall muscles, and a pain specialist to explore ongoing symptom management. Psychological support can help address distress, sleep disruption, and daily-life impact, while bowel or urinary specialists may be involved for relevant symptoms. In 2025, a review found that care involving multiple specialties could reduce pain and improve sexual function in women with chronic pelvic pain, but the evidence remains uncertain due to limitations in study designs and variability in care models. The article emphasizes that the management plan should be tailored to the individual, incorporating their experiences and preferences, and should pursue a route that addresses all relevant contributors to pain.

Implications for patients and clinicians

Healthcare providers should reassess persistent pain by considering whether endometriosis remains or has recurred, while also evaluating other conditions and changes in pain processing. The goal is to develop a holistic treatment plan that reflects patient needs and experiences, potentially reducing pain and improving quality of life by addressing multiple pain sources rather than focusing solely on endometriosis lesions.
