What causes endometriosis pain?
Endometriosis occurs when tissue similar to the uterine lining grows outside the uterus, often on the ovaries, ligaments, or pelvic sidewalls. That tissue responds to your hormonal cycle much like the uterine lining does, causing inflammation and, over time, scar tissue that can bind pelvic structures together. The surrounding pelvic floor muscles often tighten protectively in response, adding a second, very treatable layer of pain on top of the underlying disease.
Tissue similar to the uterine lining grows in places it should not, most commonly around the ovaries, fallopian tubes, or pelvic sidewalls. Because it still responds to your hormonal cycle, it can bleed and inflame the surrounding area each month even though it has no way to leave the body. This is a medically diagnosed condition managed by your gynecologist, and physical therapy works alongside that care to address the pain and tension it leaves behind.
Repeated inflammation can create adhesions, bands of scar tissue that bind organs to the pelvic wall, bowel, or bladder. These adhesions restrict the normal gliding motion your pelvic organs and connective tissue need. Gentle manual therapy can improve tissue mobility around these restrictions, which often eases the pulling, dragging sensation many women describe.
When pain is a regular visitor, the pelvic floor muscles often respond by staying braced and tight, even between flare-ups. That protective guarding becomes its own source of pain, separate from the endometriosis itself. It is one of the most common and most treatable pieces of the puzzle, and it responds well to breathing and relaxation training.
When pain persists for years, the nervous system can become more sensitive, amplifying signals that would otherwise be minor. This does not mean the pain is imagined. It means the pain-processing system itself needs gentle, graded retraining alongside treatment of the tissue, which is exactly what a paced physical therapy approach is built to do.
A guarded pelvic floor changes how you stand, sit, and move without you realizing it. Over time, that compensation loads the low back, hips, and abdominal muscles differently, creating secondary aches that can feel disconnected from the original pelvic pain but are very much related to it.
