A little basic information about pain:
Nociceptive pain is when the nerve picks up a signal and tranports that signal to the central nervous system. The signal may contain information about a tear in skin or tissue, sores, dryness, infection or inflammation. Common to nociceptive pain is that it often responds well to painkillers. The pain is typically felt as dull, nagging, gnawing, throbbing, and aching.
Neuropathic pain is when the nerves are damaged or don’t act normally. The nerves may be entrapped or dysfunctional. It might be harm from earlier injury to tissue ie. scar tissue causing pain. The pain is typically experienced as burning, biting, stinging, tightening, cutting, chilling, and haunting.
