On Sept 8th (last week), I saw blood at the end of urinating. My wife and I were worried so I went to see our Dr the next day and he tested my urine for infections and the tests came back negative. Knowing that a UTI would be the lesser of the other issues, I was hoping that I had a UTI. I go in tomorrow for a CT scan (no contrast) in hopes that I might have a kidney stone. I really do not have any other symptoms except a slight & occasional mid back pain. The pain has been mild for a month or two and I had thought that I was driving to long or had hurt my back lifting something. No fever, no issue peeing, no burning feeling when peeing. I haven't seen any blood in my urine the last two days. I think if I had more pain of more symptoms it might be easier for us to know what is going on. Everyone that I know that has had kidney stones share a common experience of tremendous pain which I have not had. Has anyone like me experienced mild symptoms that has experienced gross hematuria? Any thoughts or words of advice would be very appreciated.
