Possible to be partially allergic to eggs?

Okay, this needs correcting. Yes, heat can denature proteins. However, some proteins require more heat and more time to be denatured than others. Lemon protein can be denatured if it's cooked in a soup. Wheat protein needs around 600 F for 30-60 minutes to become denatured - like what it would take to self-clean an oven. BIG difference. There has not been a lot of research on just how much heat is needed for each type of protein to be denatured, however, the 8 major allergens (of which eggs is one) seem to require more heat to denature than most others. A person allergic to eggs absolutely can react to cooked eggs. For egg allergies, you can be allergic to the yolk, the whites, or you could have an allergy to both. Also, if you have had an allergic reaction, even a mild one, it takes a while for your IgE level to drop back to normal, usually a few days. And if your IgE level is elevated, it makes you more likely to have an allergic reaction. This is sometimes why you can not seem to react on one day and then react on another - you can have a low reaction without symptoms that can still raise your IgE levels and make you susceptible for the second reaction. You need to get tested by a doctor, and you NEED to avoid eggs. With this type of reaction, it can go from hives today to anaphylaxis tomorrow. Allergists don't know what triggers the change, but you really need to at least get checked and get an epi-pen, just in case.

sounds like you could be allergic. go to a doc and get allergy tested

Of course you have an allergy here. I would not consider it 'partial' - though clearly not life threatening. Proteins are denatured not eliminated, though it is correct their structure is altered with the heat of cooking. Stay away from raw egg whites - easy.
