cold sores
"I'm a 40 year old UPS guy.  I started getting cold sores 3 years ago.  They used to happen only when I was working out in the cold but now in the middle of July.  They always last 2  weeks.  I've tried Abreva, Lycine, campo-phenique, ice, limiting argonine-rich foods, nothing worked. 
Today, day 3 of abreva and campo-phenique failing, I was full blown, huge pustules on my lip looking like they were about to explode so went to my doctor.  I took 1GM of valtrex this AM and within 45 minutes it started feeling different and my lip started tingling.  By 5PM it was softer/less pressure. I took another 1GM at 7PM.  I just looked in the mirror at 10PM and the pustules are much smaller and never popped.  So far so good!"
