cold sores
"By far the best (and only) medication to ever help my cold sores. I would get large painful blisters at the center of my upper lip that would stretch out to below my nose. They would take a week to break open, and at least a week but usually two for the scab to heal over and after that I would deal with a large red patch of skin there for another several weeks before fading back to normal. With my last outbreak I had Valtrex on hand and took the first dose within a few hours and two days later it's almost completely healed and no one has even been able to tell I had/have a sore. I will always have this medication on hand! I've been dealing with these for 10  years, not to oversell it but this medication has changed my life!"
