I have had severe neck/upper back muscle spasms on one side of my body for over a year. I've tried chiropractic, massage, physical therapy and medication (cyclobenzaprine hydrochloride). Nothing has provided significant relief from the pain which continues to gradually worsen. I recently discovered (when applying for new health insurance) that my medical chart contains a diagnosis of torticollis, although I do not have the involuntary tilting of the head that usually accompanies this condition. How should I proceed?
