answer:Not all ice cream has eggs. In fact, I think most store bought doesn’t have eggs. To answer your question, yes I think some people think they have allergies and they don’t. Also, sometimes allergies come and go. So they might have been sensitive or allergic and now aren’t and they don’t know things have changed. My husband thought he was allergic to penicillin, but one time when I really wanted him to take it the doctor asked him why he thinks he is allergic and my husband said his mom told him the doctor asked what happened when he took, and my husband had no idea. Long story short, he takes penicillin with no problem.
