pain
Pain can be described as a distressing sensation in a particular part of the body. Because pain is a complex and subjective phenomenon, an adequate definition is difficult to develop. The International Association for the Study of Pain's widely used definition states: "Pain is an unpleasant sensory and emotional experience associated with actual or potential tissue damage, or described in terms of such damage."[1]
Pain motivates the individual to withdraw from damaging situations, to protect a damaged body part while it heals, and to avoid similar experiences in the future.[2] Most pain resolves promptly once the painful stimulus is removed and the body has healed, but may persist despite removal of the stimulus and apparent healing of the body. Sometimes pain arises in the absence of any detectable stimulus, damage or disease.[3]
Pain is the most common reason for physician consultation in most developed countries.[4][5] It is a major symptom in many medical conditions, and can significantly interfere with a person's quality of life and general functioning.[6] Psychological factors such as social support, hypnotic suggestion, excitement, or distraction can significantly modulate pain's intensity or unpleasantness.[7][8] In some arguments put forth in physician-assisted suicide or euthanasia debates, pain has been used as an argument to permit terminally ill patients to end their lives
