[YEA] I have gotten cold sores for years, I used to pick it with a alcohol soaked cotton swab (burns like the Dickens) but dries it up and goes away quickly. Recently I have started using DMSO when I started getting one, 3 times a day. By the next it was nearly gone and by day two there was nothing there but a blemish which disappeared soon after. Since then I have not had a single out break! I still use dmso one or twice a week and I even tested myself by doing things to make an outbreak occur but nothing happened.
Also avoid nuts especially walnuts for some reason they used to make me have an incident almost every time especially when I was dehydrated.
