Pain is defined by the International Association for the Study of Pain as "an unpleasant sensory and emotional experience associated with actual or potential tissue damage and described in terms of such damage." Pain falls into a number of sub-categories including acute pain, recurrent acute pain, chronic pain, chronic pain syndrome, chronic pain disorder, psychogenic pain, fibromyalgia syndrome and somatoform pain disorder.
This policy deals with chronic pain and chronic pain syndrome. The American Medical Association Guides to the Evaluation of Permanent Impairment has identified 8 characteristics to be considered when making a diagnosis of chronic pain. The existence of 2 or more of these characteristics may indicate chronic pain syndrome.
