Since last November 2010 I have had UTI systems every single month. I would call the doctor and they would put me on antibiotics thinking it was a UTI. Then May 2011 I started having hematuria every month, sometime I would have no symptoms then I would start to have blood clots in my urine and extreme pain. 
When they did the urine culture there was no bacteria present. I have horrible insurance and cannot afford a cystoscopy or Ultrasound of the kidneys.
Now I am experiencing back and shoulder pain, see white flakes in my urine and I am having hematuria again. It is very frustrating and I hate to stay on antibiotics forever.
