I have unprotected sex with boyfriend of 3 years. Hadn't seen him in about a month & went to visit. We had sex and a couple days after getting home I started itching and thought it was from shaving. They look something like blisters but don't pop out, its like they stay under the skin. There is nothing oozing from them. I've been using cream to help the itching. Was afraid I had contacted Herpes from boyfriend but the spots are all outside where I shave. I had some pills for Shingles (which I had a while ago) VALACYCLOVIR & ACYCLOVIR the doctor had prescribed for them. I see they are used for Herpes also so I started taking them. I still have the rash a week later. What can it be?
