I am a 28 y/o male. Four weeks ago, I had unprotected sex with a questionable woman in her early thirties. A day or two after, I noticed a large lump on my penis, in between the head and the foreskin. There are two other smaller bumps next to it, both on the head. They are not painful and have not changed much in four weeks.
I immediately saw a doc who said it wasn't an STD but maybe balanitis. He gave me antibiotics and a cream. All of my blood work came back negative. After ten days, with no change in my symptoms, he gave me a steroid cream. After no change I went to a free clinic, where the doc took one look and said Herpes.
A different, very reputable PCP examined me more closely than the other two docs, and said it didn't look like an STD, with none of the classic symptoms of herpes and they didn't look like genital warts. He put me on stronger antibiotics. He said that it may take ten days. It's been five, the symptoms haven't gone down, and there's even a new spot that looks like a mole on the head of my penis. It does not resemble the other three areas. He did a culture and blood test for herpes.
I didn't know at the time she hasn't had an HIV test in about four years. She said she's had unsafe sex since then with people she trusts. She also just told me that her latest pap smear indicated that she has either HPV or cervical cancer, but has never had any other symptoms.
I am worried I had open skin on my penis right before we had sex. We were on a beach and the sand may have irritated it.
Could she have given me HIV and that's why my symptoms haven't responded to any treatment? I had an ingrown hair on my arm that got infected and hasn't healed in a few days. They took blood five days ago, and yesterday I noticed a bruise on my arm from the needle. Both are very unusual for me.
Yesterday, 26 days from exposure I got another HIV test. Would the antibiotics cause a false positive?
Am I an extremely high risk for HIV?
