What are the signs of pudendal neuralgia?<\/h1>\n\n

Burning, shooting or tingling pain in the area served by the pudendal nerve (perineum, anus, genitals), worse when sitting and eased by standing or lying down. The Nantes criteria require five essential criteria: pain in the territory of the pudendal nerve, worse when sitting, that does not wake you at night, with no objective loss of sensation on examination, and relieved by an anesthetic block of the pudendal nerve (Labat et al., 2008<\/a>).<\/strong><\/p>\n

These signs do not allow you to diagnose yourself.<\/em><\/p>\n

Where does the pudendal nerve run?<\/h2>\n

It arises from the sacral nerve roots S2 to S4, wraps around the ischial spine and runs through Alcock\u2019s canal, which is formed by the fascia of the obturator internus muscle.<\/strong> This is why contraction of this muscle can tighten around the nerve from the inside, in addition to seat pressure. \u2192 Anatomy of the pudendal nerve<\/a><\/p>\n

Many people also have less pain when sitting on a toilet seat, which leaves the perineum unsupported; this is not a Nantes criterion. In our files, 36 of the 58 people who answered this question have pain on one side, or stronger on one side.<\/p>\n

What can cause similar signs?<\/h2>\n

Painful contraction of the pelvic floor, a fissure or an abscess, a urinary tract infection, prostatitis, vulvodynia, endometriosis, tailbone pain (coccydynia) or pain referred from the lower back.<\/strong> Each of these causes needs its own treatment.<\/p>\n

How is it diagnosed?<\/h2>\n

Through the medical history, a clinical examination and an anesthetic block of the pudendal nerve, which is one of the five essential criteria; MRI is mainly used to rule out other causes.<\/strong> The path to diagnosis is often long: \u2192 The diagnostic odyssey and central sensitization<\/a><\/p>\n

What about sitting?<\/h2>\n

Sitting makes it worse through pressure, protective contraction and immobility; this is where adjusting your seat acts, alongside medical care.<\/strong> \u2192 Why does sitting make perineal pain worse?<\/a>, then Which cushion for pudendal neuralgia?<\/a><\/p>\n

What other questions do people ask?<\/h2>\n

Can you have pudendal neuralgia without pain when sitting?<\/strong> It is atypical: pain that worsens when sitting is a central criterion.<\/p>\n

Can a cushion cure pudendal neuralgia?<\/strong> No. It avoids sustaining the stresses of sitting.<\/p>\n\n
