What is Pain?
Pain is the unpleasant sensation that is experienced following an injury.
It’s the sensation that the body creates to signal the injured person that the body has sustained damage. The aversive nature of the pain experience is one of the factors that motivates us to prevent injury and care for our injuries.
Pain is the most frequent reason for consulting a physician or receiving emergency medical care. It is also the most frequently cited reason for taking sick leave from work. The health care resources that are used for treating pain, and the enormous societal costs associated with occupational disability make pain the most costly of all symptoms that arise following injury.
