Description

The sensation of pain results from adverse physical or emotional experiences that cause actual or perceived tissue damage. The most common pain sensation, nociceptive pain, results from physical tissue damage, which is experienced through the nervous system. A second type of pain, neuropathic pain, stems from a malfunction in the central and/or peripheral nervous system. Because its source is internal, neuropathic pain may lack an obvious origin. This three-course suite explores the etiology, diagnosis, and prognosis of neuropathic pain.
