Pudendal Neuralgia: Symptoms, Causes, and Treatment in the UK

Pudendal neuralgia is a severe form of chronic pelvic pain that originates from the pudendal nerve. In the UK, this condition is increasingly recognised by healthcare professionals as a distinct clinical entity, though it was historically poorly understood. This specific nerve passes through the lower pelvis and is responsible for sensation in the perineum, rectum, and genitals.

When this nerve becomes compressed, inflamed, or damaged, it can cause persistent, debilitating pain. Because the symptoms often overlap with other conditions such as endometriosis or chronic cystitis, patients may go for long periods without an accurate diagnosis. Understanding the unique characteristics of pudendal nerve pain is the first step toward effective management and relief.

The hallmark of pudendal neuralgia is pain that is positional. For most British patients, the pain becomes significantly more intense when sitting down and tends to improve when standing up or lying flat. Symptoms are typically felt in the pelvic floor, perineum (the area between the anus and the vagina), or the genital area.

Common symptoms reported by patients include:

• Burning or 'Electric Shock' sensations: A sharp, stabbing, or searing pain in the pelvic region.
• A feeling of 'fullness': Many women describe it as feeling like there is a foreign object, such as a golf ball, inside the vagina or rectum.
• Sensitivity: The skin in the pelvic area may become so sensitive that wearing tight clothing or underwear becomes unbearable.
• Bladder and bowel changes: You may experience a sudden urgency to urinate or feel like your bladder is never fully empty.
• Sexual dysfunction: Pain during or after sexual intercourse is common.

Unlike some other pelvic conditions, pudendal neuralgia is usually caused by physical irritation or entrapment of the nerve. The nerve can become squeezed as it passes through the ligaments in the pelvis.

Common trigger factors in the UK include:

• Prolonged sitting: Long-distance cycling or office-based work involving long hours in a seated position without breaks.
• Childbirth: The physical strain and stretching of the pelvic floor during vaginal delivery can damage the nerve.
• Pelvic surgery: Scar tissue following surgery in the pelvic area can occasionally entrap the nerve.
• Chronic constipation: Frequent straining can put excessive pressure on the pudendal nerve over several years.
• Trauma: A heavy fall onto the 'sit bones' or a pelvic fracture.

Diagnosing pudendal neuralgia can be complex. In line with NICE (National Institute for Health and Care Excellence) guidelines for chronic pain, a GP will first look to rule out other causes such as infection or malignancy. There is no single scan that 'shows' pudendal neuralgia, although MRI scans may be used to look for physical entrapment points.

Clinical diagnosis is often based on the 'Nantes Criteria', which look for specific indicators such as pain when sitting and the absence of pain at night. A specialist may also perform a pudendal nerve block; if an injection of local anaesthetic near the nerve provides immediate (though temporary) relief, it strongly suggests the nerve is the source of the pain.

Many women feel embarrassed discussing pelvic pain, but seeking medical advice early is vital. You should consider booking a consultation with an online doctor if you have persistent pelvic pain that has lasted for more than a few weeks. Speaking to a GP online offers a discrete and convenient way to discuss your symptoms, review your medical history, and determine the next steps.

An online doctor can provided valuable initial guidance, such as:

• Assessing your symptoms against common pelvic conditions.
• Providing advice on paracetamol or anti-inflammatory medications.
• Advising on the necessity of a physical examination or a referral to a gynaecologist or urologist.
• Issuing a sick note if your pain makes it impossible to continue with your normal work duties, particularly if your job involves constant sitting.

Effective treatment for pudendal neuralgia usually involves a multidisciplinary approach. In the UK, the NHS pathway often begins with conservative management before moving to more invasive procedures.

Lifestyle Adjustments

Using specialist cushions (often doughnut or 'U' shaped) can take the pressure off the perineum while sitting. Avoiding trigger activities like cycling and managing constipation through a high-fibre diet is also recommended.

Pelvic Floor Physiotherapy

A specialist women's health physiotherapist can help identify if your pelvic floor muscles are 'hypertonic' (overly tight), which can squeeze the nerve. They use targeted exercises to relax the pelvic floor and improve nerve mobility.

Medication

Standard painkillers like ibuprofen often fail to help nerve pain. GPs may prescribe neuropathic agents such as amitriptyline, gabapentin, or pregabalin, which are designed to calm down overactive pain signals from damaged nerves.

Specialist Procedures

If conservative measures fail, patients may be referred to a Pain Management Clinic for nerve blocks, radiofrequency ablation, or, in rare cases, decompressive surgery.
