Help, not sure what’s wrong with me.

i had sex with 2 sex workers almost a month ago, oral and vaginal, both with a condom.

Roughly a week after i started to notice slight discomfort when urinating. ive also got an ache on my testicles and upper legs.

Ive had a urine test done and it all came back negative. very confused, anyone else had this? could this be phsychological?
