Does Central pain arises only when the original insult was central
False. The term central pain is applied when the generator of the pain is believed to be in the spinal cord or the brain. The original insult may have been peripheral (nerve injury or postherpetic neuralgia), but the pain is sustained by central mechanisms. The basic process may be central sensitization. Central pain also may occur after central injuries, such as strokes or spinal cord injuries. The pain tends to be poorly localized and of a burning nature.
