I just had surgery and had upper body temors for hours after my general anesthesia. The same thing happened to me a year ago and they thought that I was allergic to reglan, a drug used to combat nausea. However, they did not use this drug this time and the same thing happened. The doctor who gave me the anesthesia felt that it could be from my fibromyalsia. I was wondering if anyone else had such effects after general anesthesia.HELP!!! I have to have another surgery soon.
