Chronic neuropathic pain and its control by drugs.
The medical treatment and some currently known aspects of the aetiology of five neurogenic pain states are discussed. Neurogenic pain can be described as pain resulting from noninflammatory dysfunction of the peripheral or central nervous system without nociceptor stimulation or trauma. The enormity of the field has limited this review to post-herpetic neuralgia, complex regional pain syndromes, phantom pain, trigeminal neuralgia and diabetic neuralgia. Evidence suggests that many neurogenic pain states are not effectively controlled. This may be due in part to a lack of understanding of the aetiology of these conditions and to the lack of high quality studies evaluating existing treatments. A compact review of the literature is presented with some treatment options and possible future directions. Where appropriate surgical management and physical therapy have been discussed; however, a thorough appraisal of nondrug treatments was not the main priority of this review.
