I feel bad that no one has been able to help you. I know I would definitely be looking for a new doctor. Anyway, I have multiple autoimmune diseases and your symptoms sound like it could be anyone of them. I have Crohns, Celiac, Autoimmune Hepatitis, and Fibromyalgia. It is often hard to tell which one is causing the problem. I've had some awesome Dr's at Mayo and I know they will get to the bottom of this. I'm sure you know that they can't test you for Celiac if you have already eliminated the gluten. Take Care and hang in there!!
