Neuropathic pain: The sensation you are describing is neuropathic pain. It comes from a pinched, inflamed ir damaged nerve. The most common causes of your symptoms are a disk problem in the neck, injury, or the early phase of shingles. If your symptoms have been present for a while you should talk to your doctor about a definitive diagnosis and treatment options.
