Thanks for your prompt reply. I am glad you think the 2 g of azithromycin would address NGU and gonorrhea. I have had some mucus stands in my urine for 2-3 months (if not longer) which started before my sexual risk exposures I outlined. This could be prostatitis. Looking at today's posts, you had a lot of similar questions today. Thanks again!
Welcome to the STD forum.
It seems you either had NGU due to the oral sex exposure, or relapse of your previous prostatitis. From you description, I cannot tell which -- but the timing is right for NGU, perhaps due to normal mouth bacteria. You have been treated in the standard way with azithromycin, in a dose that also would have cured gonorrhea (although I doubt that is what you had).
1) HIV and chlamydial infection are very rare, if they occur at all, from oral sex. Gonorrhea unlikely -- usually causes symptoms in 2-5 days, with large amounts of pus dripping from the penis. But as noted above, NGU is a good possibility.
2) The treatment was correct and addresses all the likely possibilities.
3) No test of cure is needed if your symptoms clear up and do not recur.
It seems your doctor is knowledgeable about STD diagnosis and treatment, and probably also understands prostatitis. Return to him or her for reevaluation if your symptoms don't clear up or return.
Good luck-- HHH, MD
