Am I at risk of HIV after having unprotected oral sex?

Hello doctor,

I am a 26-year-old male. I only received unprotected oral sex for roughly two minutes around 46 days ago from a commercial sex worker. I did not have any intercourse. I do not know her HIV status. I had an episode of diarrhea immediately after within the next five days and it resolved after taking Levofloxacin and Lomotil (which I guess was food poisoning as it occurred the very next day). I tested for all STI’s (chlamydia, gonorrhea, hepatitis, and HIV) 14 days after exposure and all came back negative. It is an early test for HIV. I traveled abroad for vacation in the meantime and I took Azithromycin 500 g for three days as I had throat ache and mild fever in 20 days after my potential low-risk exposure. I developed a sore on my upper gum and it has been there for 16 days. It is painless now. Also applied Orasore ointment. Recently after 40 days after exposure, I developed small red bumps only in my hand and behind the ear with a sore throat and mild fever. The doctor has prescribed me an Amoxicillin antibiotic for five days and Vizylac once for five days. My throat is feeling better now.

My questions are:

1. Am I at risk of HIV?
2. Are these recurring mild fever and sore throat acute HIV symptoms?
3. Is the sore in my mouth a concern?
4. As I have had an eye transplant and my immune system is weak would I have contracted HIV from my exposure?

Hello doctor,

Thank you for your response. I had been on Prednisolone tablet one year back after the transplant. But now I am only applying Prednisolone eye drops once a day. Last known, I took Prednisolone three months ago for wheezing for three days. I took the test in an STD clinic. I am not sure which test that was. I presume it should be an antibody test. I will be taking the test in another 14 days. That will be a total of 63 days after exposure. I knew it was a negligible risk but since these sorts of symptoms appeared I panicked. As my fever, sore throat, and red lumps (only in my right hand and behind my ear total of six or seven scattered) are going away they got nothing to do with HIV. Please let me know your advice. Am I overthinking myself?

Thank you doctor,

I will be taking the HIV test once I am back home in two weeks. I can say that there was no visible bleeding In her mouth when this happened. I have attached the photos of the skin lesion that I have. The ones in the ears have gone already. It has actually reduced after Amoxicillin and Vizylac and few are gone already. Should I still be worried about HIV risk?
