question: Hi doctor,I had a protected sex with a sex worker five weeks before. She gave me oral sex after wearing a condom, then we had vaginal sex with the same condom for about 10 minutes. Muscle and joint pain on legs started after one month of act. I also got cold with this. I had flown after which I got this cold. I am very much worried after going through symptoms of HIV on the internet. Also, I do not know the quality of condom used. Do these symptoms relate to HIV? What is the chance of me contracting HIV? Should I get tested?
