I'm 24, and have an aspirin allergy. When I take anything with aspirin my lips, chin, and the area around my eyes gets itchy, and swollen so I take Tylenol instead. Lately though I've noticed I'm starting to get the same reaction when I take Tylenol as I do when I take aspirin. Can you suddenly become allergic to something you weren't allergic to before? If I'm allergic to both aspirin, and acetaminophen what else can I take that doesn't have either of those in it?
