You had no risk of HIV because you can't get HIV from touching HIV or oral activities. You are so safe that you don't even need to test.
HIV is instantly inactivated in air and also in saliva which means it is effectively dead as soon as it leaves someone's body so it can't infect from touching or oral activities. It doesn't matter if you and they were actively bleeding or had cuts at the time either because the HIV is effectively dead.
Only adult risks are unprotected penetrating vaginal or anal sex or sharing needles that you inject with but you didn't do that so you had no risk. This sentence is all you need to know to protect yourself against HIV.
Even with blood, lactation cuts, rashes, burns etc air does not allow inactivated virus to infect from touching it or oral activities. The above HIV science is 40 years old and very well established so nothing you can add will make your situation a risk.
Your doctor has diagnosed your nose issue so there is no point is thinking it is ARS, which everyone on this forum thinks they have but so far I have never seen anyone with ARS btw.
Thank you @anxiousfor responding quick. That was very satisfying. But my anxiety is being taking control each time I find answers.cos I have never had it this long, neither the allergy nor rash.
I'm concerned over the rashes and ongoing cough, or what could this be if I haven't had an possible exposure?
How does ars rash appear?
Is this allergy a symptom that ars claws up?
( the one I have keep appearing day by day when other fades red slightly raised rash on arms and sometimes face.)
