I have had blood in my urine on and off since the summer when i had a severe bladder infection w/ an extreme amount of blood in my urine, to the point that they thought my kidneys were shutting down. I have done many UAs and my doctor has come to the conclusion that i have chronic hematuria because i am so athletic and small (16 yr old female, 105lbs active 8x a week for 2hrs at a time). Is there any way to get rid of this hematuria? any undlerlying causes? As well sometimes there are small blood clots in my urine. Any help? :S thanks!
