cold sores
"I'm 19 years old and I've been getting cold sores ever since I was young...the last few years I would get them a couple times a month sometimes a new one every week. I've been taking valtrex for a few months now and I've gotten only 3 times (which is a major improvement) because I was sick and my immune system was down. But they went away after a day or so. I'm so so happy"
