What is pain

Some dictionaries define pain as “An unpleasant sensation, occurring in varying degrees of severity as a consequence of injury, disease, or emotional disorder.” The International Association for the Study of Pain defines pain as “An unpleasant sensory and emotional experience associated with actual or potential tissue damage, or described in terms of such damage.” Inherent to either of these definitions is the recognition that pain always has both a physical and emotional component. It is both a physiologic sensation and an emotional reaction to that sensation. In certain instances, pain may be experienced in the absence of obvious tissue injury; yet the pain is no less “real.” New information emphasizes how important it is to view the experience of pain as a complex neurobiological experience that is influenced by multiple factors occurring at multiple areas of the peripheral and central nervous system. Some of these factors are easily identifiable, while others are not as of yet.
