i received oral sex from another male which lasted less than 30 seconds. I asked if he was disease free and he said he was. I went to clinic the next day and was treated with Rocephin and Zithromax. I was tested for NGU, Gonnoreah, and Chlamydia three weeks after treatment and the results were negative. Six weeks and five days after the encounter, I was tested for Syphilis and the results were negative. I have had no symptoms that I am aware of but am very anxious and am closely searching for symptoms every day. I recently found a small white bump on the shaft of my penis slightly above the hair line. It is raised and waxy looking but not red or open and the tissue around it is not swollen. It has not changed appearance in the two days since I noticed it. I have read threads here and see that the risk of catching any infection from oral sex is pretty low but have some questions:
One thread said the treatment I describe would prevent/cure NGU, Chlamydia, Gonn, and Syphilis. What does prevent mean and why would drugs other than pennecillin G prevent syphilis?
Since my RPR test was at six weeks and five days, can the results be trusted and is there any possiblity that the treatment would have delayed sypmtoms or a positive result? I saw a thread that said it takes 6-8 weeks to become positive.
My doctore looked at the little bump and said it doesn't look like anything to worry about but to keep an eye on it. Considering my history, is it possible that the bump could be the beginning of a chancre?
Do I need further testing to rule out syphilis or any other infection and am I at risk of transmitting any infection to others?
Thank you for providing this service.
