Pudendal neuralgia is a rare problem with the pudendal nerve that can affect both men and women. The pudendal nerve runs through your pelvic region, including your genitals, urethra, anus, and perineum. Your perineum is the area between your anus and genitals. The condition is also known as pudendal neuropathy, pudendal nerve entrapment, cyclist's syndrome, pudendal canal syndrome, or Alcock's syndrome.
Pudendal neuralgia can cause pain, especially when you sit. Men with pudendal neuralgia may have pain in the buttocks, scrotum, penis, and perineum. Women with pudendal neuralgia may have pain in their buttocks, vulva, urethra, and perineum.
