The pudendal nerve is found in the pelvis. It is the biggest division of the pudendal plexus and is located behind the sacrospinous ligament. The nerve extends from the sacral plexus, through the pudendal canal, the perineum, and the gluteal area. Conditions Pudendal neuralgia can cause both bladder and anal incontinence. Other symptoms include chronic constipation, rectal pain, and sexual dysfunction. Pudendal nerve entrapment is another form of pudendal neuralgia. This condition causes phantom pain in the lower regions of the pelvis, penis and scrotum, vulva, anus, and perineum. Individuals diagnosed with pudendal nerve entrapment have described pain when sitting down. This pain decreases when standing or removing pressure. Pudendal motor latency test Doctors can perform a pudendal nerve motor distal motor latency test to determine if there is nerve damage. This test measures the motor function of the nerve. This test will give doctors an indication if pudendal neuralgia is present. Pudendal block test The pudendal nerve block test is performed by doctors when they suspect a pudendal nerve entrapment. Doctors will use an anesthetic to numb the pudendal nerve. If the symptoms are eradicated, then pudendal nerve entrapment exists.
