cold sores
"I got cold sores since I was kid. I'm 24 yrs old now and get them about 4 times a year due to stress or if I get sick or something. I got prescribed Valtrex 3 years ago and it has done wonders. Once I feel the tingling I would take a pill and literally the cold sore would stop in its tracks. Even if it starts to show a little such as a deep red I just take a Valtrex and it would stop and then I would get some make up and cover the redness and you wouldn't even be able to tell."
