hyperalgesia

hyperalgesia
   The term hyperalgesia comes from the Greek words huper (to exceed a certain boundary) and algos (pain). It translates loosely as 'exaggerated pain perception'. The term is used to denote an increased sensitivity to painful stimuli. Hyperalgesia is usually classified as a type of " hyperaesthesia. Pathophysiologically, hyperalge-sia is associated primarily with the sensitization of nociceptors, due, for example, to the chronic use of morphine or other analgesics. The term hyper-algesia is used in opposition to the term hypoal-gesia. It should not be confused with " allodynia, " hyperpathia, and " hallucinated pain.
