Several types of diseases and conditions can cause pelvic pain. Chronic pelvic pain can result from more than one condition.

Pelvic pain can arise from your digestive, reproductive or urinary system. 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.

Pelvic pain might also be caused by irritation of nerves in the pelvis.
