herpes simplex
"I found out I contracted genital herpes from an ex boyfriend about 5 years ago. It initially felt like a cut on my vagina that itched and burned. Went to Dr next day and sure enough- herpes (ugh). I take the medicine as needed and it works like a charm. If I do feel one coming I take 400mg  three day for about 4-5 days. Clears right up. I also used to get cold sore a few times a year- haven't since taking this medicine. It's AMAZING. Just wish I never had to find out about it."
