Purpose:

Postherpetic Neuralgia is a painful nerve condition that can occur when nerve fibers are damaged following an outbreak of shingles. The purpose of this study is to identify and study abnormalities in the nerves and cells in the of patients with postherpetic Neuralgia (PHN) and characterize changes that could be responsible for causing nerve pain.
