I've been having this problem the last few months, where I get sick after I eat eggs. I can't eat them at all unless they're in baked foods or something like that. I always get a queasy feeling in my stomach, sometimes along with a tension headache. I don't know why I'm having this reaction to them, because it's never been that way. I haven't tried organic eggs yet, I'm hoping that if I do that I won't feel sick after them. I figure it's worth a shot, because I really like eggs.

Why could this be happening?
