Herpetic neuralgia is a form of nerve pain that occurs as a result of an infection with the herpes zoster virus. The virus is the same one that causes chickenpox, and it can lie dormant in the body for years before reactivating and causing shingles. Herpetic neuralgia typically affects people who have already had shingles, and it can be extremely painful. The pain is caused by damage to the nerve fibers, and it can persist for months or even years after the initial outbreak has resolved. Treatment for herpetic neuralgia typically focuses on managing the pain, which may involve medication, physical therapy, and other interventions. For some people, however, the pain can be so severe that it significantly impacts their quality of life. Post-herpetic neuralgia is a similar condition that can occur when the nerve damage from shingles is not fully resolved. This type of nerve pain can also be extremely debilitating, and treatment often requires a multimodal approach.
