I had unprotected sex back in August with someone I didn't know. About a week after, I started to itch really bad, mostly at night. This went on for over a month and then stopped for two weeks while I was on antibiotics for a urinary tract infection. The itch has come back now and so far it has lasted over 2 weeks. I have not seen any sores, but I have read that many people don't have sores. I have had very minor fever - 99.3 and swollen lymph nodes. Also it burns when I pee. Took an HIV test yesterday and it came back negative. All other STD test have come back negative. Have not done a herpes test though. Could this possibly be herpes?
