Neuropathic pain is pain that persists after an injury has healed or a disease has resolved. [when pain serve no purpose].
These are some of the neuropathic pain :
- referred pain : sensory input from skin and viscera coverage on single spinal neurons that transmit pain stimulus to the brain. Pain impulses from deep structure or organs are mislocalized to a region innervated by the same spinal segment (gall bladder to the right shoulder blade, heart to left arm or jaw).
- sensitization pain : lowered threshold for activation of nerve endings after repeated stimulation in injured or inflamed tissue.
