herpes simplex
"The first two times I ever got a cold sore I used over the counter Walgreens/CVS/Campho-phenique products and my cold sore lasted for 2 weeks. This most recent time, I noticed the red tingly bump on Saturday morning, rushed out to the store and decided to try Abreva.  I began application immediately and as directed.  By Saturday evening I was blistered. I kept using Abreva and was taking L-lysine vitamins every day. It is now day 5 and the blister is gone, already scabbed and fallen off, and now just a somewhat minor red area where the skin is still healing.  This combo of Abreva and L-lysine vitamins saved my life! Would definitely recommend Abreva and will use again if needed."
