Pain is an adaptive sensation that normally appears as a warning, activated in response to a damage of the organism. Pain serves to protect the organism to further tissue injuries. The International Association for the Study of Pain (IASP) defined pain as “an unpleasant sensory and emotional experience associated with actual or potential tissue damage, or described in terms of such damage” (see definition on the IASP homepage at www.iasp-pain.org). Pain can be generally divided into two categories, acute and chronic pain: acute pain is properly a sudden warning pain which signals that something is wrong in the body. If the cause is not removed acute pain may develop in chronic pain, which is persistent and debilitating.
