This is confusing because condoms reduce the rate of transmission by 96%. Were you ever tested previously to know your herpes status?
In order to know if these are herpes lesions or some other skin bacteria that you may have contracted, it should be swab tested to find out what if anything is growing there. It would be helpful to have a lesion to evaluated when you are there for the best diagnosis. I would be surprised, given 1 gram of Valtrex a day, if these are herpes lesions.
