Herpes Simplex
"I&#039;ve gotten cold sores since I was young. It&#039;s a common thing among a lot of people, but it happens to me normally once a year around winter. My lips end up drying out and when they get chapped that&#039;s when a cold sore ends up forming. I  am not completely sure why, but whatever makes it lay dormant gets aggravated. I actually went to a local drug store to get a cold sore treatment when I found Lysine. Unfortunately, I didn&#039;t catch it in time but it took the pain and itching away almost immediately. It&#039;s shortened the amount of time it would normally take a cold sore to heal when the blisters have already formed. It&#039;s better than the other products I have used, and a lot more efficient."
