Hello, Ive been getting cold sores (mouth herpes) since I was a kid, I got tested to see if I actually have Mouth Herpes and I do. Ive been taking Lysine for 2 years and Vitamin A recently. They ve been working but about a week ago, I got 2 at the same time, then they went away and another appeared. Is there any medicine that will 100% keep them away? But also wont make my mom go broke. Thanks, Cassie a 15 year old
