In some people who've had shingles, pain continues after the rash is gone. Because chickenpox and shingles are caused by the herpes zoster virus, problems that happen after you've had shingles are called "postherpetic." Neuralgia is nerve pain. So pain that continues after you've had shingles is called postherpetic neuralgia.

Doctors don’t know why some people get postherpetic neuralgia
Most people who have postherpetic neuralgia are older than 50
Pain medicine and creams can help lessen your pain
The chickenpox and shingles vaccines can help prevent shingles and postherpetic neuralgia
Go to a doctor right away if you still have pain after shingles has gone away. Treatment works better if you start as soon as possible.
After you've had chickenpox, the virus stays in your nerve roots, near your spine. Sometimes the virus becomes active again and causes a very painful rash (shingles) on the part of your skin connected to the infected nerve root.
The shingles rash goes away on its own. But a few people continue to have severe pain where the rash was. Doctors don't know why this happens in some people and not others.
If you only have mild pain, doctors will tell you to use an over-the-counter pain medicine (such as acetaminophen) or cream (such as capsaicin or lidocaine) to lessen your pain.
