cold sores
"I typically get cold sores when the weather changes drastically or when I'm stressed. Combine those two and its cold sore central! They would usually form and then last for at least 7 painful days. I FINALLY got prescribed valacyclovir and I must say, it's working very well. The first time I took it I was mid cold sore so I didn't get the full effect. This time I took it at the on sight of a cold sore and it worked wonderfully. It didn't prevent the cold sore, but it went from inflammation to healing after merely 2 pills without the pre-sore, open sore, and crusting phases. I HIGHLY recommend this for anyone suffering from cold sores."
