Detailed Description:
Patients with chronic neck pain, lasting since at least 3 months, are recruited from our pain clinic. After verification of inclusion and exclusion criteria, patients consenting to enter the study are assigned randomly to one of the following groups: 1-Amitriptyline 5 mg for 2 months 2- placebo for 2 months. Co-morbidities and other painful conditions are noted, and then clinical evaluation of the patient is performed; pain is assessed according to Visual Analog Scale, anxiety, depression, insomnia and disability are evaluated by adapted scores (Bergen insomnia scale, neck pain disability score, neck pain diary & anxiety and depression score). Patients are followed at 1, 2 and 3 months and outcome measures are assessed.
