Well, after suffering most of my life and going to doctor after doctor, and being diagnosed with fibro too, I finally found a doctor that was able to help me find the real diagnosis. I am gluten intolerant, and it can really mess you up bad, which include auto-immune diseases and others to numerous for me to write about here. You can read about them at:
http://www.glutenfreesociety.org. This is an incredible site for someone just to learn about it, and it can give you info to take to your doctor so that you can at least be tested for this. It took me 13 long years and I literally almost lost my mind, which is another symptom, if your sensitive to gluten, you can really be in trouble like I have been. Good luck to you all and I hope your flare ups stop.
