I dont think that it has anything to do with hiv.Because of your fear you connect everything to hiv.I advice you to stop searching for symptoms in your body because the more you search the more you will find.Mind is a very powerfull dsp and fear is it's fuel. I was there and I know.If you can't get over this then wait untill 4 weeks and then do a full std palet test.But I would not bother with this if I were you.You can allways consault an std specialist and have it heared from an official oppinion.
I have been feeling a pain in my knee for the whole day and I have iced it and it still does not go away. It is not an unbearable pain but it is an annoyance, could this be a symptom for HIV or any other STD or am I overthinking?
As the experts say here,you don't have to worry about hiv since you had protected sex. I don't think that getting oral sex for a second is danger for any std either. I can not see how the oral sex that you had could infect you with an std near your mouth where the pimples are located.I am no expert on this matter though I am just giving you my advice because I have done so much reading over those matters.I would suggest to you that you ask this question on the std's forum.I can tell you for sure that you have not an hiv risk because you used a condom.
