Long-term pelvic pain that originates from damage/irritation of the pudendal nerve – a main nerve in the pelvis
Supplies areas including the
Lower buttocks
Area between the buttocks and genitals (perineum)
Area around the anus and rectum
Vulva, labia and clitoris in women
Scrotum and penis in men
PotentialCauses
Compression of the pudendal nerve by nearby muscles/tissue – sometimes called pudendal nerve entrapment or Alcock canal syndrome
Prolonged sitting, cycling, horseback riding or constipation (usually for months or years) – can cause repeated minor damage to the pelvic area
Pelvic surgery
Broken pelvis
Damage to the pudendal nerve during childbirth
A growth pressing on the pudendal nerve
Symptoms
Pelvic pain (any of the areas supplied by the pudendal nerve can be affected), which can feel like a burning, crushing, shooting or prickling sensation
Can develop gradually, suddenly or be constant
Numbness and pins and needles in the pelvic area
Increased sensitivity to pain
Feeling as though there’s swelling or an object in your perineum
Needing to go the toilet frequently or suddenly
Pain during sex
Difficulty reaching orgasm
Erectile dysfunction in men
Diagnosis
Vaginal/Rectal exam: To see if the pain occurs when pressure is applied to the pudendal nerve
MRI scan: To check for problems such as a trapped pudendal nerve and to rule out other possible causes
Nerve studies: A small device inserted into the rectum is used to stimulate nearby nerves with mild electrical impulses to check how well the nerves are working
Nerve block injections: Painkilling medication is injected around the pudendal nerve to lessen/eradicate pain
Treatment
Nerve pain medication
Pelvic physiotherapy: Learn exercises to relax your pelvic floor muscles and other muscles that can irritate the pudendal nerve
Painkilling injections: Local anaesthetic and steroid medication for temporary relief
Decompression surgery: Tissue removal (if there is any) to keep it from pressing on the pudendal nerve
Nerve stimulation: A small device is surgically implanted under the skin to deliver mild electrical impulses to the nerve and interrupt pain signals sent to the brain
Avoid things that make the pain worse ie: cycling, prolonged sitting
