Hello, I am 35 year old man. 3 months ago I had symptoms including hematuria, fever, pain. urin test was positive for E-Coli. I took Marcobid for 7 days. all symptoms gone. about 4 days after I finished medication I had a jelly-like discharg, it was dark yellow even my semen was really dark in color. my doctor thought I had STD, I did a urine test for that and the result was negative for all STD s. About 4 days ago I noticed a blood coming out from my penis after I urinated, I had the same thing on the next day, no ther symptoms but I feel a kind of discomfort or fullness on groin area. Please advice at your earliest convinience. Best regardsm
