I have experienced non-stop severe cold sores for
almost three months. I know how I got infected, and know I've never had them before. They cover the outer half of both lips, top and bottom). I've tried acyclovir and generic valtrex, with no relief. Not even a two hour break. Still taking generic valtrex (1 gram twice a day). I am taking Thompson's lip relief (lysine, vit c, zinc, bioflavanoids) and an immune support (andrographis,olive leaf, echinacea), and have been for a few weeks.
