herpes simplex
"So I started getting cold sores when I was young but as I grew older I had stopped getting them. Anyway I got a cold sore 2 days before my 20th birthday, right? I mean I was completely devastated so I searched online and found some reviews on Abreva. I headed out to purchase it (yes, small tube, very expensive). I thought it was worth the try but I wasn't expecting much. Two days later my cold sore was barely visible and to be honest, I'm only doing this review because I do think the product was worth the price and it actually works."
