urethritis, NGU?

I am a male, my question is regarding a sexual encounter about six months ago. Two weeks after the event I tested negative for chlamydia and gonorrhea. The test was a NAAT urine sample, and the only requirement was no food or drink except water 2 hours prior to testing. I experienced no real symptoms such as inflammation, discharge, or pain when urinating, but I noticed I did have a slight burning sensation after ejaculation. My doctor suggested monistat which I took for 3 days, 6 weeks after the event. I cannot tell whether it worked but my symptom did clear up shortly after. My questions are: 1) Was my symptom related to NGU and I should I be concerned if I was not treated properly? 2) Do I need to be concerned about a false negative for chlamydia and gonorrhea, additional testing? I just want to make sure I am fine. Thanks doctor.

It is conceivable your symptoms reflected undiagnosed NGU.  However, most NGU has discharge as a more prominent symptom than just "slight burning".  False negative results for either gonorrhea or chlamydia are rare with NAAT; and in any case, even without treatment, virtually all cases of urethral gonorrrhea and the large majority of chlamydial infections clear up on their own within 6 months.

So all things considered, I see no reason for concern that you continue to harbor NGU or any other STD at this time.  But of course if in doubt, don't try to figure it out online; see an STD-knowledgeable health care provider, such as your local health department STD clinic.  But truly I see no reason for concern here.

Thank you doctor. Considering NGU, chlamydia, and gonorrhea can be cured with something as simple as an antibiotic, I will make an appointment right away. One last thing, is there an antibiotic you recommend, or is it too late for treatment? How long does it take for these infections to produce long term complications if left untreated? Maybe I am being overly worried here, but I am going to take the extra precaution. Thanks again doctor.

[H. Hunter Handsfield, M.D.]

No complications in men can develop from uncomplicated infection.  You are not at risk for adverse outcomes.  I have no further comments; all the rest is between you any whatever provider you visit.  You can be sure s/he won't find anything wrong.

Thank you doctor. The reason I ask is because ashastd.org states if left untreated in men NGU and chlamydia can result in epididymitis or infertility.

[H. Hunter Handsfield, M.D.]

True, but not without symptoms.  The infertility occurs only because of epididymitis, and epididymitis sufficient to cause it is an obvious, painful condition.  And actually, male infertility due to chlamydia or gonorrhea is very rare.  In 30+ years in the STD business, I have never seen or even heard of a case.
