Thanks, Mimi. I probably do need to step back and wait until I get an actual diagnosis.
When I first got the blood in my urine, I went to the internet and saw that excessive exercise was a possible cause, although perhaps not the most common cause. That's why I waited for 3 weeks before going to the doctor. Once I called the doctor, I got all caught up in the idea of BC, because it seemed like it was either that or kidney stones, and since I don't have pain, well....
Then I visted this forum, which is just excellent in all ways for people who have BC, but since everyone here has BC, you don't get many stories about hematuria that don't turn into BC.
Anyway, thanks for the different perspective. You're right--I need to wait for a diagnosis before just assuming I have it. And I'm so sorry for all your problems--although I'm very happy you don't have BC, it has to be worrying to have the repeated hematuria with no diagnosis. I know the waiting for me is a hard thing--I just want to know what's going on!
