Yes, Patricia, I did have the CT scan. It came back fine--they said there were no abnormalities. He never mentioned a renal ultrasound, but thank you for bringing it up. When I get the results of the 24 hour urine thing, I'll ask him about that. I feel like he now thinks he's going to get rid of me and refer me to a nephrologist, or whatever they're called.
I haven't been doing any heavy exercise lately--6 weeks ago when this started, I'd started a more vigorous exercise program, and that is why I waited a couple of weeks before going to the doctor.
After my visit today, I googled kidney disease and found one site that said that sometimes they never find a cause for hematuria!!! I sure hope that's not the case here. I can't imagine going forever with this and not knowing a cause. It just doesn't seem right.
