A painful response to a non-painful stimulus.

An increased painful response to a normally painful stimulus. It is more appropriately used for cases with an increased response at normal threshold or at an increased threshold. Hyperalgesia can be due to both peripheral and central changes.

An unpleasant abnormal sensation, whether spontaneous or evoked.

Pain in an area or region that is anesthetic.

A syndrome of sustained burning pain, allodynia and hyperpathia after a traumatic nerve lesion, often combined with vasomotor and sudomotor dysfunction and later trophic changes.

Pain initiated or caused by a primary lesion or dysfunction in the central nervous system.

Pain initiated or caused by a primary lesion or dysfunction in the nervous system.

Pain initiated or caused by a primary lesion, dysfunction, or transitory perturbation in the peripheral or central nervous system.

An abnormal sensation, whether spontaneous or evoked. (Not described as unpleasant)

An experience of mental suffering for which no organic disease substrate or where a bona fide organic disease has become overelaborated in its psychologic, emotional and behavioral significance. The dx is made with inclusionary not exclusionary criteria

Pain arising from nociceptors surrounding blood vessels and associated with nociceptor induced inflammation.

Abnormally painful reaction to a repetitive stimulus, as well as decreased threshold.
