Document Summary
Hard to define objectively because although can be associated with tissue injury, it is often time reflective of the feeling that injury has occurred (private experience) Persistent (3 months plus: nociceptive or neuropathic neuropathic => central (spinla cord injury, stroke) or peripheral (post-herpetic neuralgis, difficult to treat (arthritis). Increased willingness to try meditation if suffer from neuropsychiatric symptoms: differentiate between acute and chronic pain. Persistent (3 months plus: nociceptive: nociceptors in tissues send pain signals to the cns. Neuropathic: damage to the nerve tissue itself causes pain symptoms. Neuropathic => central (spinla cord injury, stroke) or peripheral (post-herpetic neuralgis) Complementary alternative medicine (cam: pain is said to be a private experience. What is meant by this? feeling that injury has occurred (private experience: pain perception has several dimensions which can be measured experimentally using different tests. Threshold: point at which pain is first experienced, measured against a stimulus gradient. Electric stimulus threshold measured in ma. (sensitivity is inverse of threshold)
