The task of medicine is to preserve and restore health and to relieve suffering. Understanding of pain is essential to both these goals. Because pain is generally understood as a signal of many diseases, it is the most common symptom that brings a patient to physician's attention. The function of the pain sensory system is to detect, localize, and identify tissue-damaging processes. Since different diseases produce characteristic patterns of tissue damage, the quality, time course, and location of a pain complaint and the location of tenderness provide important diagnostic clues and are used to evaluate the response to treatment.
Until the 1960s, pain was considered an inevitable sensory response to tissue damage. In recent years, great advances have been made in our understanding of the pathophysiology and mechanisms that underlie pain and in the treatment of pain. But, despite improved knowledge of underlying mechanisms and better treatment, many people who have chronic pain receive inadequate care.
