May be a cold sore: It sounds like you may have a cold sore. These are caused by a virus in the herpes family. Less likely, you may have an allergic reaction to something that touched your lips. If there is pain or tingling, it would suggest a cold sore. Only itching would lean more towards an allergic reaction.
