Chronic idiopathic pain syndromes.

In this review, we outline a rational approach to the complex problem of chronic idiopathic pain syndromes. We focus principally on musculoskeletal pain disorders and emphasize the differences between adults and children. The different nomenclatures in use are clarified and the epidemiology is examined. The key clinical findings are highlighted and different therapeutic approaches are reviewed. The evidence base for the interventions reviewed include both 'medical' and 'non-medical' approaches. Practical problems and issues are dealt with throughout the review in order to construct a pragmatic approach that the authors intend to be of everyday use to the clinician and allied health professionals.
