I have been tested negative for STD's. My Urologist injected Iodine via intra venis and took x-rays. Everything is normal. He says don't worry about it just drink a lot of water. Come back in 3 months. The symptoms are no burn in the morning after a good nights sleep. Throughout the day the burn increases with each urination. But, oddly enough, after ejaculation, I am fine for the following 3 days and then it starts again. Any suggestions?
