That symptom matches my reaction to egg whites but the weird thing is, it's only some forms. I can eat hardboiled eggs no problem (probably because the allergen has denatured), but not most other forms itch while baked goods are very hit or miss. The worst are meringues and macaroons.
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.
