A month ago, I had an unprotected one-night stand with a woman other than my wife.
Three days later, I noticed a small amount of thin milky discharge as well as a slight burning when urinating.
The next day I went in to the clinic and left a urine sample for chlamydia and gonorrhea tests. I also was given 2g Azithromycin to cover either infection.
Meanwhile, my partner also went in for a checkup. She relayed that her doctor did not notice any redness, swelling, discarge, or lesions. Also a swab was viewed under a microscope which she said was not visible for bacteria or yeast, and she left a sample to be cultured.
The next day my symptoms subsided except for a slight irritation or tickle toward the end of my urethra. I also had intermittent achiness in one or the other testicle. It alternated.
9 days after the encounter (5 after taking the Azithromycin) the culture for my partner came back and gave her a clean bill of health, no STDs. She did not say what tests were run.
That same day I was able to see my doctor, who examined me and said whatever I had, it was gone and that the achiness could be addressed by "relieving some pressure" by which I'm sure he meant masturbation. He said that since she came back clean, I probably had a non-chlamydial NGU.
I wasn't with my wife until 9 days after treatment when my tests came back negative.
Then I went on vacation for a week and hardly ever noticed irritation or achiness.
Fast-forward a month from the encounter to now. Now that I'm back and I have time to dwell on what I've done, the occasional urethra tingliess has returned along with the slight testicular ache. Being somewhat obsessive I researched it and am worried that I might have trichomoniasis. Either that, or its anxiety, which I also have a lot of. I would honestly love for it to be in my head.
Do you think I have anything to worry about, given my partner's test results? Again, she didn't specify what exactly was run with her culture.
Thanks for your help.
