Pain can be categorized as neuropathic, nociceptive, or idiopathic. This chapter discusses neuropathic pain, which is pain caused by dysfunction of the nervous system. Nociceptive pain is the result of tissue damage that may or may not include damage to the nervous system. Idiopathic pain encompasses several poorly understood pain disorders that are not associated with tissue damage and includes many pain disorders that have been considered psychogenic in origin. Pain is the number 1 reason that patients seek medical attention. It is an alarm mechanism warning of tissue damage and potential danger.
