I think i may have hiv or another std?

Testing: You did not list symptoms or exposure history. Even if you did, you need a local evaluation to confirm or exclude this collection of diagnoses. Only with a review of exposure history, exam and testing can this be answered with confidence.

?OK?: I hope you do not have these, but if you are at a high risk for these type of infections (such as having high risk sexual activity) than you should see a dr. And get tested for such. Best wishes.

Why?: I assume you think this because you having a sore throat and painful urination? Hiv/std infection is always possible if you had unprotected sex with someone you are not familiar with. You should always use a condom when having sex. See a doctor today so he can properly assess you.
