Can adenomyosis cause back pain?

Yes—adenomyosis can cause back pain, especially low back or sacral aching that flares with your cycle. Because adenomyosis involves endometrial-like tissue within the uterine muscle, the uterus can become enlarged and tender, and that deep pelvic pain can refer into the back.

Back pain from adenomyosis often travels with other clues like heavy or prolonged bleeding, severe cramping, pelvic pressure, pain with sex, or fertility challenges. It’s also common for adenomyosis to overlap with endometriosis, which can further amplify pelvic and back symptoms—so persistent back pain around your period deserves a whole-pelvis evaluation, not just a “back problem” workup.

If your back pain is cyclical or paired with heavy bleeding or deep pelvic pain, our team can help you sort out whether adenomyosis, endometriosis, fibroids, or a combination is driving it. We’ll typically start by reviewing your symptom pattern and prior imaging and, when needed, discuss next-step imaging (like a targeted ultrasound or MRI) and treatment paths that match your goals.
