I have been through the same thing! I am just finishing up testing for celiac disease. It is a gluten intolerance. Pay attention to what you eat and within the hour if you are beside yourself trying to scratch your skin off...it is worth checking out. All you ask your doctor for is a trans gluten antibody test for celiac disease. The easiest is to get the blood test before you eliminate gluten from your diet. It is a starting point...good luck.
