My back is not usually involved, but for too long now I've experienced severe, acute left side pain from as high up my body as my left ear/jaw area, taking in all the left side of my neck, collar, shoulder, left arm, etc. These episodes can last as long as 4 hours. They have become more frequent, longer lasting and more severe. I am out of my mind with pain. My primary doctor says I have fibromyalgia. Two years ago he sent me to an orthopaedic surgeon who recommended surgery for stenosis. I did not want to have the surgery and did not have it. I've been told that it is referred pain, but it is mind-altering and excruciating, no less. Any ideas on refining the condition as it only occurs to my left side? I am a white, 51 year old female. It is increasingly becoming unmanageable. Help. Thanks. Joy in Florida
