One day, after about a week of aggressive pumping, I started pissing a lot of blood. I mean my blood was 100% red. The toilet looked like someone got murdered in after I used it. There was a lot of pain too. I went to the ER and they diagnosed it as a UTI since there was blood. I was prescribed antibiotics which cleared the blood fast, the pain took longer. Anyways, my family doctor got the lab report on the urine back and it found no bacteria in it which means it wasn't a UTI , well unlikely one. So I did the battery of test for cancers etc. All was clear. Anyone have this? Hard to believe I would piss blood for a day if I "broke" something and why would the antibiotics work? Then again no bacteria so... Anyone have an experience like this? PS. I was tested for every STD 6 mths apart, nothing came up.
