Surely, there are plenty of places on your body where you love a little tingling, but right above your lip before a first date, an interview, or your reality show tryout isn't one of them. What starts as a tingle and ends as a full-blown cold sore can be as painful as it is embarrassing. They can recur when you have a cold, which is why they're called cold sores. They typically last two weeks. The leading cause of cold sores: herpes infections, which are transmitted through saliva, through kissing, or sharing other people's cups. This is called herpes type 1, not to be confused with the genital variety called herpes type 2. While you have a cold sore, kissing or giving someone oral sex can transmit the herpes virus to that person, so refrain. Don't share cups, toothbrushes, forks, or other things that touch your mouth while you have a cold sore, either.
