I had UTI and severe stomach pain. Came positive for UTI in urine analysis. After a five day course of Flaxovate and Norflox 400 i have hematuria: traces of blood in urine. It continues for a week. Second urine analysis states no pus cells. My periods were to be during the second week when i started hematuria. Doctor did a physical internal check up, all looked ok. Also the urine is clear with only blood strings sometimes or when I wipe. My question is why blood, mild abd pain and back pain if no uti. Also I did lift some heavy things before hematuria started. But when I did the first test due to severe abdominal pain the ultrasound looked normal.
