What is Postherpetic Neuralgia?
Postherpetic neuralgia (post-her-PET-ic noo-RAL-jah) is a painful condition affecting your nerve fibers and skin. Postherpetic neuralgia is a complication of shingles.
Not everyone who's had shingles develops postherpetic neuralgia. However, postherpetic neuralgia is a common complication of shingles in older adults. The greater your age when you develop shingles, the greater your risk of developing postherpetic neuralgia.
Postherpetic neuralgia may be debilitating long after signs of the original herpes or shingles infection has disappeared. It becomes more common with increasing age.
