HIV? Or am I paranoid?

I slept with a prostitute in Vienna three weeks ago. Actually, three different ones in two night. I know that it's stupid but I was feeling down. Anyway, I used condoms with all three and they didn't break. I have felt that under my armpit there is a small hard ball. Very small, but it's painful. However, last week I was lifting and l
after the lift I felt the pain. It went away for a couple days but now it's back. Do you think I have aids? I haven't had any other symptoms.

How can you be sure? Please elaborate?

Latex condoms, when used consistently and correctly, are highly effective in
preventing transmission of HIV, the virus that causes AIDS. In addition, correct
and consistent use of latex condoms can reduce the risk of other sexually
transmitted diseases (STDs), including discharge and genital ulcer diseases.
While the effect of condoms in preventing human papilloma virus (HPV) infection
is unknown, condom use has been associated with a lower rate of cervical
cancer, an HPV-associated disease. Laboratory studies have demonstrated that latex condoms provide an essentially impermeable barrier to particles the size of STD pathogens.
