Pain is a common human complaint and can be alarming, especially when an individual cannot provide a proper explanation. It seriously impairs the lives of millions of individuals around the world and remains the main reason why a patient reports to the doctor. A lot of research has been done and is still going on to understand the physiology of pain and to invent ways and means to eliminate or control the intensity, duration and frequency of this factor which affects quality of life of individuals. Many theories have been proposed over the years and a knowledge of them will help us to understand the complexity of pain.
