Post Herpetic Neuralgia
Herpes (or shingles) is a viral infection of the skin. Mostly it is associated with small red vesicles (fluid filled blebs) on the skin and resolves completely.
But in a few patients a burning pain starts after the herpes has resolved. This is called post herpetic neuralgia. The elderly and those with diabetes are more likely to have it.
Sometimes the pain is severe and disabling. Fortunately, this pain nearly ALWAYS resolves.
Now there are several very effective medications and physical measures to control this pain. Managing this pain is sometimes quite challenging for the treating neurologist.
