Standard general treatments for neuralgia include anti-inflammatory medications, narcotic pain medications, anti-seizure medications, antidepressants and topical capsaicin creams, Healthline states. When the cause of neuralgia is known, specific treatments can include better control of blood sugar, surgery to relieve pressure on the nerve, physical therapy or a nerve block.
Neuralgia is a painful sensation along a damaged nerve, which can be quite severe, says Healthline. Neuralgia most frequently occurs in the face or neck but can occur anywhere on the body. Common types of neuralgia include postherpetic neuralgia and trigeminal neuralgia. Postherpetic neuralgia occurs as a side effect of shingles, a viral infection, and can occur anywhere in the body and last for years. Trigeminal neuralgia occurs in the nerve that travels from the brain to the face and is generally caused by pressure from a blood vessel on the nerve.
Other infectious diseases that can cause neuralgia include HIV, syphilis and Lyme disease, Healthline explains. It can also be caused by chronic diseases such as multiple sclerosis and diabetes, both of which can damage the myelin sheaths that insulate nerves. Injuries caused by accidents or surgery can also damage nerves and lead to neuralgia. Chronic kidney disease and porphyria are other possible causes.
