It sounds like you are getting very superficial care. You need to be worked up for urethritis, epididymitis, and prostatitis. You need to be cured so that you don't end up with a chronic problem. You need to know exactly what is wrong, not generally what is wrong with a shrug of the shoulders. The science behind treating what you may have is very inadequate. I would also examine your last sexual partner or partners if it were me. Best of luck to you.
