herpes simplex, suppression
"I've suffered from cold sore since I was a baby. I remember having 3 at once in middle school and a huge one my senior year. In my 20s, I started to get them 5 or more times per year. The pain was unbearable sometimes as they flared up and weeped. I finally asked my doctor if there was something I could do. She gave me a 90 day script for valtrex and it's been amazing. If I catch it in the tingle stage,  it barely forms. One time,  I've missed the tingle and a blister has started to form.. it was puffy the next day and then It was flat and not puffy the NEXT DAY! Never broke and weeped, but just gradually went away. 

I recommend this a million times over."
