Brief Summary

It is known, that a so called "pain memory" usually evolves in chronic pain syndromes which both aggravates the disorder and modifies the patients pain perception. Thus, the principal object of pain therapy is to "delete" this dysfunctional pain memory. The combination of medication, physiotherapy and psychological therapy seems to be the most effective treatment. This study investigates the effect of a concomitant Dronabinol medication (Cannabinoid) on the effectiveness of behavioral therapy. It is hypothesized that the combination of behavioral therapy and Dronabinol will be most effective in deleting the pain memory.
