Document Summary

May occur because of sympathetic arousal, as it occurs in response to vigorous sports and seems to diminish pain sensitivity: in contrast, stress and psychological distress may aggravate the experience of pain. Measuring pain: one barrier to the treatment of pain is the difficulty people have describing it objectively, pain does not have these objective referents. If you have a lump, you can point to it, or if a bone is broken, it can be viewed using an x-ray. Theories of pain: early theory: traditional models suggested that pain resulted from transmission of signals from site of injury to brain & that amount of pain experienced was directly proportional to amount of tissue damage. In phantom limb pain: phenomenon commonly found among amputees, an individual experiences pain in a limb that is not there. Generated from body-self neuromatrix, & not sensory inputs.
