DEAR DOCTOR K: I suffer from what my doctor calls "chronic neuropathic pain." What are my treatment options?
DEAR READER: There are two main types of pain. Nociceptive pain results from an injury to tissues outside your nervous system. Burns, sprains and broken bones are all examples of nociceptive pain. Tiny nerve fibers are always present in tissues. When the tissue gets injured, the nerve fibers detect it. The signal they send the brain is nociceptive pain. The signal says to the brain: "Do something to avoid further injury!"
