Pudendal nerve entrapment

Pudendal nerve entrapment is a cause of chronic pain in which the pudendal nerve, located in the pelvis, is entrapped or compressed. This can be caused by pregnancy, scarring due to surgery, accidents, heavy and prolonged bicycling that can eventually thicken the sacrotuberous and/or sacrospinous ligaments and trap the nerve between them, or anatomic abnormalities that have the pudendal nerve fused to different parts of the anatomy, or trapped between the aforementioned ligaments. Pain is worsened by sitting, and can include prickling, stabbing, burning, numbness, and the sense of a foreign object in the urethra, vagina, or rectum. Decompression surgery is done primarily in Nantes, France; Houston, Texas; and in Egypt.
