My doctor mentioned that he thought fibromyalgia could be caused by long periods of stress or a traumatic emotional experience. However, I didn't really have either at the time which is why I kept telling him I don't think it is fibro. We finally found that my testosterone levels were significantly low, but we still can't figure out why and we can only really get them to the very bottom of the normal range by doing all of the things he suggests. It sure would be nice to figure out what they heck caused the change...
