Hi:
Did your Doctor look into Celiac Compression Syndrome? Or MALS? Look that up. Most people with those symptoms have MALS/ Celiac Compression Syndrome. That can be corrected by surgery. Meanwhile give up all dairy, gluten and fructose for at least a month and see how you feel. If you eat rice please buy organic rice. The pesticides sprays and god knows what else they used on potatoes, vegetables and grains can slowly destroy your gut and overall health.
Good luck.
