hi....i had an allergy test done many years ago, when i was a teen (i'm 30 now) ...and the allergist said i was allergic to peanuts (or peanut butter - can't remember which) .. i kept eating peanut butter, peanuts, nuts in general and i never had any type of reaction...but, lately (2 months or so) i break out in hives all over mybody and i get angioedema, and feel lightheaded ...could this be due to that supposed peanut allergy?

Summarized question: What causes hives on body and angioedema?
