You probably have a genuine food allergy to egg. I don't see egg in OAS lists. I see some research saying that common egg allergens are destroyed by cooking as well (though this is not true for all cooking methods or all food allergens). I would see an allergist. It's probably a good idea for you to carry an epi-pen. Even if you've only had low severity reactions so far, it's always possible that the next one will be severe, and egg is hard to avoid.
