what cause pelvic pain
Some causes of chronic pelvic pain include: 1  Endometriosis. This is a condition in which tissue from the lining of your womb (uterus) grows outside your uterus. 2  Tension in your pelvic floor muscles. Spasms or tension in the pelvic floor muscles can lead to recurring pelvic pain. 3  Chronic pelvic inflammatory disease.
Recently, doctors have recognized that some pelvic pain, particularly chronic pelvic pain, can also arise from muscles and connective tissue (ligaments) in the structures of the pelvic floor. Occasionally, pelvic pain might be caused by irritation of nerves in the pelvis.
