First time poster here but wanted to ask a question regarding an encounter I had with someone recently. I met this new woman who I slept with around September at the time I thought nothing of it but then started to get a bit nervous once I noticed she was a bit more promiscuous that I initially thought. We had unprotected oral and protected vaginal sex. I only slept with her 2 times so I got really nervous and got std tested. The first test was only 1 week after our second and last encounter but it was at least 28-30 days from the first encounter and everything came back negative so that gave me a baseline that I didnt have anything. However, I did go to the doctor to get something on my penis checked out because I thought I might have had HSV but it turned out it was nothing to worry about he said I should get tested again just to be sure I dont have anything, which I will get tested tomorrow. But since that doctor visit and its been about 4 weeks since that last encounter with this lady I have had a constant knee pain for the past week and a sudden sore throat. I was not sure if the sore throat was due to me talking at work but that was really odd. Since then I have been in a bit of a panic that I might have developed some HIV symptoms. I wanted to ask could these be symptoms or just unrelated things that have happened. There was no problems with the condom breaking but the last encounter I went sort of limp and the condom slipped a little bit but was still on my penis it never fell off at that point I just stopped and just have unprotected oral which is a low risk for HIV. 

thanks !
