I am a heterosexual non-drug user. Almost all sex I have had was protected, though several times I had unprotected sex while in a committed relationship.I was diagnosed with herpes and had what i believe was a first outbreak. I had a sore along with fever, fatigue and swollen nodes. There was also a patch of skin which turned blackish then yellowish on my penis. It was about the size of a quarter and has since become the size of a pea. All symptoms disappeared except the sore when i took varacyclovir and the sore was cultured. It was negative for herpes and they said negative for bacteria, though I'm not familiar with how bacterial cultures work. I took a course of azithromax when I began my valtrex course and that's around the time the sore shrunk dramatically, but it's been shrinking very slowly since then. Is it likely that my symptoms were ARS, which happened to enter latent period around the same time i took my valtrex? And what do negative cultures of the sore mean? It is going away, just slowly.
