Since I'm not seeing it, I also can't be sure. However, most herpes lesions have a whol cluster of blisters, not one or two, and mostly they occur on the lip itself, not at the corner. So I'm guessing it easn't herpes. If you get the same thing again in the same vicinity, see your doctor right away (or at least take a good picture to shoe the doctor.)
Quick Question: Can taking VALTREX before a sexual encounter minimize the risk of contracting Herpes. And if so, how long (or after) the encounter do you recommend taking it?
There is no way to prevent infection of herpes except to wear protection.
valtrex only prevents outbreaks for the infected.
there is currently no cure or 100% prevention of herpes.
