6 weeks ago I had protected sex with a stripper.no oral sex After sex, I have this bad habit of cleaning my penis with hand wipes/sanitizer soap and baby powder.Which I did after having sex with the stripper. About 8 hours before having sex with her, I had regular unprotected sex with my girlfriend whom I have been dating for 2 years. (Before ever engaging into unprotected sex with my girlfriend we did a complete std screening, and never had any problems for 2 year)s. The next day, in the evening I felt my urethra burning. It wasn't painful but it was noticeable. I slept it off and was fine the next day til the afternoon. This time I also felt the sole of my feet tingling. There was no discharge of any type. That same night I went to the ER, the doc checked for any infection and took a urine sample/swab. Tests for chlamydia/gonorrhea later came negative. He however gave me azithromycin/ceftriaxone just in case. The symptoms seemed to go away for 2/3 days but came back. So I went back to the ER, different doc who checked me again and found nothing he concluded I had urethritis and gave me doxcycline for 7 days. After the 7 day course, the symptoms were not as bad but I followed up anyways with my general doc who prescribed me with BactrimDS/Desoximetasonecream0.25;I was complaining about some discoloration and dark Tiny spots on my glan. Also there seemed to be dryness on my penis. I only used Bactrim for 3 days because I had a terrible reaction to it (Hives/throat swelling/night sweats/yellow stool). The throat swelling went on for 2 weeks, every time after a meal. I have no other symptoms aside from yellow stools. I have been back/forth to hospitals and did dozens of Blood/stool test + general check ups and everything comes up normal. My girlfriend, the stripper and I all took HIV tests, all came out negative. (I had done 3 different ones because I was scared). My question is what could have been the cause of this urethra irritation? Was it the condom? Chemicals?
