Cold Sores
"This is the third time that I have gotten a cold sore. The first two times I tried to make it go away on its own. I tried everything from tea tree oil to Abreva. Since my cold sore started with a tingle on Saturday night, I couldn&#039;t get to my doctor until Monday morning. By that time I had two cold sores on my lower lip, millimeters apart and my lip was swollen to the size of a grape.  He gave me 1 gram valacyclovir, twice a day. By that night I noticed that the first cold sore had a scab and that it shrunk in size.  The next morning all of the swelling was gone and the cold sores were The second blister didn&#039;t pop yet but it looked like it was getting smaller. Although they say to take this medicine when you first feel the cold sore coming"
