Postherpetic neuralgia is pain due to nerve damage caused by shingles. Symptoms include sharp, stinging pain on the skin, itching, and pain lasting months after the shingles outbreak.
A vaccine for shingles can be given to reduce the risk of getting postherpetic neuralgia. Common drug classes used to treat postherpetic neuralgia are anti-epileptics, TRPV1 agonists, and local anesthetics.
