It does sound like he is having an allergic reaction to something. It doesn't necessarily have to be from food. When he is in the dusty and musty areas, who knows what kind of germs, fungi, or allergens could be floating around?! It's good that he is getting allergy testing. Perhaps than both of you will find the answers you seek. Good luck to him! Btw, does the Zyrtec help him or at least ease some of his symptoms?
