Abstract

Pain was classically defined as the sensation evoked by injury. This attractively simple definition neglects the observed phenomena of behavior and physiology and was replaced by the International Association for the Study of Pain in 1979 with the following definition and with a crucial coda:

Pain is an unpleasant sensory and emotional experience associated with actual or potential tissue damage, or described in terms of such damage. Pain is always subjective. Each individual learns the application of the word through experience related to injury in early life. It is unquestionably a sensation in a part of the body but it is also always unpleasant and therefore also an emotional experience.
