Abstract

Abstract:Clinical concepts of pain are reviewed and the basic parameters for the analysis of pain symptomatology are outlined. Several classic pain syndromes and symptoms are placed in perspective and, whenever feasible, attempts are made to review the pathophysiologic concepts upon which these considerations are based, however hypothetical. The treatment of pain is a complex subject which includes drugs, surgery, psychology, physical medicine and rehabilitation, and cannot be considered within the scope of this review. However, treatment will be effective only when directed toward correction of pain at its origin. It is hoped that a review of underlying mechanisms will assist the physician in approaching pain from a physiologic standpoint, resulting in a more effective relief of symptoms, regardless of the cause.
