I have had sex with a guy whom I known for years two to three weeks ago. Anyway, in march, he had sex with a guy who he doesn't know very well. He is most certain that the guy he had sex with is not hiv positive, but I'm sure it's possible. I, on the other side, haven't had sex with anyone besides him.
We've had unprotected sex both ways, both of us reversing from top to bottom. He claims that he didn't have an orgasm while in me, but I don't think that matters. And he also said that he didn't have any symptoms of early HIV infection, while I have, on the other side. It's now two to three weeks after it happened, and I've been having this dull pains in inner arms, reaching from my palm up to above my elbow. It hurts when I move my arms and it doesn't seem like a sore muscle (also knowing that I didn't pursue any physical activity that would cause a sore muscle).
My lymph nodes are also quite swollen and I've felt really fatigued and tired in the last few days. Altough I didn't have fever or temperature, I have grown feeble a bit yesterday, but it went away today. I also had a strong cough which led to me coughing out blood through saliva. That can also be a sign of smoking, so I didn't take that too serioiusly.
I think I might be a little paranoid, but the pain in my arms sure exists. If you think that may have been concerning something else, I would appreciate your help anyways. I'm only 18 and soon going to college, so I don't really have anyone to talk to about this, so any help is really welcome. My parents don't know about any of this, nor do my best friends. I'm extremelly scared to go get tested and I don't know what to do.
