Try going gluten free for 2 months. Seriously. Family member had issues like this and tried many docs. No results after lots of testing. Tried going off gluten for other reasons and everything cleared. To go gluten free, only eat foods that are certified gluten free. Anything with any kind of grain that is not certified likely has cross contamination.
