About 7 weeks ago, I received oral sex with a condom from a prostitute. Two days after that, I came down with sore throat, cold, and pain while urinating. A nurse practitioner at urgent care diagnosed that as a sinus infection, and gave me a z-pack of antibiotics, saying it would clear up everything (she did not tests to diagnose this). I was fine, then intermittently would have pain urinating (once or twice a week). All this time there was no discharge. A later visit (three weeks later) to PCP involved CBC and urinalysis: all results normal.
I also began to notice red spots on my penis. They are small, not blisters, no fluid, and from reading this forum I assumed they are only normal discoloration of the skin. Also, based on reading here, I assumed that my protected oral sex was safe, and did not ask my doctor about STDs.
The pain during (and after) urination became constant and frequent. I returned to my PCP for another urinalsyis. This one found red and white blood cells. I am now on a 10 day regimen of 500 mg of cipro twice a day while we wait for the bacterial culture of the urine and to get an ultrasound on my kidneys and bladder. (PCP said there was no bacteria in the urine, but they were doing the culture anyway).
My questions: Do I need to worry about STDs? Is there a chance that a urine sample with no bacteria present will reveal bacteria to confirm an STD? Should I ask for some other kinds of tests?
Thanks for your time.
