What causes PN?
PN can be caused by an injury to the nerve or any disease of the nerve that causes inflammation or demyelination of the nerve. Some people have associated their PN symptoms with post-herpetic neuralgia, Lyme’s disease, multiple sclerosis, or other autoimmune illnesses. Other people can point to an injury or pelvic surgery as the start of their symptoms. Heavy exercise is considered one of the causes of PN. Activities that require repetitive hip flexion such as cycling and weightlifting can be the culprit. Jobs that require heavy lifting or many hours of sitting may be the cause. “The pudendal nerve comes from the sacral plexus (S2-S4) and enters the gluteal region through the lower part of the greater sciatic foramen. It courses through the pelvis and around the ischial spine and between the sacrospinous and sacrotuberous ligaments. It splits up into the rectal, anal, perineal and clitoral/penis branches.The nerve turns forward and downwards through the lower sciatic foramen underneath
