Postherpetic Neuralgia (Shingles Pain)
Postherpetic neuralgia is a chronic pain condition that affects nerve fibers and skin from shingles, a viral infection (herpes zoster) that produces a painful rash on parts of the body. This condition is considered a complication of the shingles virus that primarily affects populations over the age of 60. Although there is no cure for postherpetic neuralgia, there are medication and interventional pain treatments to ease symptoms.
Causes of Postherpetic Neuralgia (Shingles Pain)
The virus that causes chickenpox (varicella herpes zoster) remains dormant in the body and may reactive, resulting in shingles. Once the virus becomes active, it affects the nerve fibers and may cause severe damage. If extensive damage occurs, nerve fibers will not be able to send messages from the skin to the brain, which often results in chronic pain lasting months or years.
