Does anyone have a good 'remedy' for cold sores? I haven't had one for a long time, but this week I got the old familiar "tingling" on my lip and just knew when I woke up the next morning the cold sore would be there. And.....I was right. It hardly seems worth going to the Dr. because I don't think there is much he can do to hasten the departure of this thing. So far I've been dabbing it with alcohol.
