Pudendal neuralgia is a type of longterm (chronic) pelvic pain that originates from damage or irritation of the pudendal nerve.
The pudendal nerve is one of the main nerves in the pelvis, supplying areas such as the lower buttocks
area between the buttocks and genitals (perineum) area around the back passage (rectum)
vulva, labia, and clitoris in women
scrotum and penis in men.
Pudendal neuralgia can be very uncomfortable and distressing, but help is available and there are several treatments that can be tried.
Symptoms of pudendal neuralgia
The main symptom of pudendal neuralgia is pelvic pain. Any of the areas supplied by the pudendal nerve can be affected.
The pain may:
- feel like a burning, crushing, shooting or prickling sensation
- develop gradually or suddenly
- be constant – but worse at some times and better at others
- be worse when sitting down and improve when standing or lying down
Other symptoms can include:
- numbness and pins and needles in the pelvic area
- increased sensitivity to pain – you may find just a light touch or wearing clothes uncomfortable
- feeling as though there’s swelling or an object in your perineum – often described as
- feeling like a golf or tennis ball
- needing to go the toilet frequently or suddenly
- pain during sex, difficulty reaching orgasm, and erectile dysfunction in men
Causes of pudendal neuralgia
Pudendal neuralgia can occur if the pudendal nerve is damaged, irritated or squashed (compressed).
Possible causes include:
- compression of the pudendal nerve by nearby muscles or tissue – sometimes called pudendal nerve entrapment or Alcock canal syndrome
- prolonged sitting, cycling, horse riding or constipation (usually for months or years) – this can cause repeated minor damage to the pelvic area previous surgery to the pelvic area
- a break in one of the bones in the pelvis
- damage to the pudendal nerve during childbirth – this may improve after a few months
- a noncancerous or cancerous growth (tumour) pressing on the pudendal nerve
- In some cases, a specific cause isn’t identified.
When to get medical advice
See your GP if you have persistent pelvic pain.
Don’t delay seeking advice if the pain is causing problems. Pudendal neuralgia can continue to get worse if left untreated, and early treatment may be more effective.
The stress of living with the condition can also have a significant impact on your physical and mental health if it’s not treated.
Tests for pudendal neuralgia
Your GP will ask about your symptoms and may carry out an examination of the area to check for any obvious causes of your pain.
If they think you could have pudendal neuralgia, or they’re not sure what’s causing your pain, they may refer you to a specialist for further tests.
These tests may include:
A vaginal or rectal exam – to see if the pain occurs when your doctor applies pressure to the pudendal nerve with their finger
A magnetic resonance imaging (MRI) scan – to check for problems such as entrapment (compression) of the pudendal nerve and rule out other possible causes of your pain
Nerve block injections – painkilling medication is injected around the pudendal nerve to see if your pain improves
Treatments for pudendal neuralgia
Treatments for pudendal neuralgia include:
- Avoiding things that make the pain worse, such as cycling, constipation or prolonged sitting – it may help to use a special cushion with a gap down the middle when sitting and try constipation treatments
- Medications to alter the pain – these will normally be special medications for nerve pain, rather than ordinary painkillers like paracetamol
- Physiotherapy – a physiotherapist can teach you exercises to relax your pelvic floor muscles (muscles used to control urination) and other muscles that can irritate the pudendal nerve
- Painkilling injections – injections of local anaesthetic and steroid medication may relieve the pain for a few months at a time
- Nerve stimulation – a special device is surgically implanted under the skin to deliver mild electrical impulses to the nerve and interrupt pain signals sent to the brain
