Neurologic Disorders Chapter 167. A complex subjective sensation reflecting real or potential tissue damage and the affective response to it.
Chronic pain has no adaptive biologic role.
Somatogenic pain may be nociceptive or neuropathic. Nociceptive pain is judged to be commensurate with ongoing activation of somatic or visceral pain-sensitive nerve fibers. Usually, the pain is part of a defined neurologic disorder. Pain believed to involve CNS processes, labeled deafferentation pain, may be subdivided into a variety of types, such as central pain after stroke or phantom pain after amputation. Treatment plans may differ depending on the temporal description of the pain.
