The role of the pain therapist in the approach to chronic headache.

Chronic daily headache (CDH) represents, for the anesthesiologists, a big match in the management of a pain which is simultaneously central and periferic, of a pain wich is psychical and disabiliting. This is a pain conducting the patient to overuse analgesic medicaments even making worse "allodynia" and the organic integrity. That's why a multidisciplinary approach to this kind of chronic benign pathology permits to improve prognosis and quality of life.
