Endometriosis is a prevalent gynecological condition known to cause various symptoms, including musculoskeletal issues such as low back pain. The association between endometriosis and lower back pain is attributed to the abnormal growth of endometrial tissue in internal areas within the pelvic region. The pelvis comprises the hip bones, as well as sacrum, and coccyx, which are part of the lower back. Consequently, any complications in these areas may lead to sensations of pain in the lower back. Since endometriosis is closely linked to the menstrual cycle, pain in the posterior pelvis tends to intensify during menstruation, particularly if endometrial tissues are present in the bowel, bladder, kidney, ligaments, or nerves within the lower back. If endometriosis is the source of back pain, it is likely to be associated with painful menstrual periods, with the pain worsening before or during menstruation. In summary, endometriosis is a common gynecological disorder that can manifest as nonspecific low back pain, likely due to a complex interplay of factors such as nerve involvement, inflammation, lesions, and adhesions. Understanding the intricate relationship between endometriosis and back pain is crucial for developing effective management strategies for individuals affected by this condition.
