I was at the gym and I had to go to the bathroom.. I urinated.. when I returned to working out.. all of a sudden the tip of my penis began to burn really bad... It was painfull for about 20 minutes.. during that time I felt I had to urinate.. but nothing would happen.. Then the pain just went away.. I had no prior symptoms... what could this be? I drink plenty of water.. my urination was clear.. This has happen before, but not as extreme as this last episode... I am out of work.. no insurance.. what would you suggest I do?
