About a month ago, I had protected sex with a woman and unprotected oral sex with her as well. Then two days after that I had unprotected oral sex and fingered a different woman. Five days later, I got a low fever of about 99 degrees. The following day I got chills, night sweats, joint pain, and a bad fever about 102 degrees that broke that same night. The next day, I got a rash that covered my entire stomach, chest, arms and legs. I went to the hospital and they told me they thought it was a viral rash. The rash went away in about 24 hours. I got an HIV RNA and fourth generation test done ten days after the last incident and then I got another HIV RNA and fourth generation test done again at 17 days from the last incident. Both came back negative. I tested the woman that I had protected sex with using Oraquick and she came back negative, but I did not test the woman that I had unprotected oral sex with.
Could this still be HIV? I have never gotten a rash like that before in my life. What are the chances that this could be HIV based on the two negative RNA tests?
