Pain is a distressful feeling that is frequently caused by intense or damaging chemical, thermal or mechanical stimuli. It can also occur without tissue damage or injury, although the patient makes reference to it. Pain is one of the body's most important communication tools, and a protective mechanism by which the body responds to noxious or harmful stimuli. The cascade of molecular events that culminate in the experience of pain in an individual is a complex neural phenomenon in which inordinate (excess) noxious peripheral stimuli are processed.
