Hello Doctor, I am a heterosexual male who has had an encounter with a sex worker on 07/31/08. I had performed oral sex on the woman for less than a minute and then proceeded to vaginal sex wearing a latex condom. During the incounter which lasted about 20 minutes, I did not ejaculate. A week later, I had a bladder infection in which medications cleared up. During the time of the infection I was tested for Chlamydia and Gonorrhea, the results were negative. I took an HIV test 1 month and 2 months after the sexual encounter and the results came back negative both times. I am worried because before I took the second test a couple weeks ago, I started noticing that the glands in my neck were a little bit swollen, but without pain. They aren't visibly swollen, but I can feel them. I used a flashlight to look at the back of my throat and it look strange. It was veiny and there were strange looking spots at the back of my throat that are not red, but a little orangy. I went a doctor and he told me that its probably a sore throat, but my throat is not sore. I have been been coughing and was congested with a runny nose. The doctor gave me a syphilis test and a mono test and I tested negative for those too. I've asked my sister who is a nurse practitioner what could be wrong and she thinks that I just have allergies and thats what caused my glads to swell. I have also been very stressed since the time of my sexual encounter, which she says could be another cause. Other than the above mentioned, I have not had any loss in appetite, fatigue, or swollen lymphs in the armpit or groin area. However, I am still very worried because of my throat appearance which scares me that it could be a cause from the oral sex that I performed on the woman. Do you think that it is just seasonal allergies or some other kind of STD or even HIV? I still plan to keep getting tested. If the results are still negative after the sixth month, should I still worry?
