question: My daughter has been having several episodes of pain in her left kidney.  Does not ever have symptoms of UTI;s but has had 6 incidental findings of UTI because we have gone to doc for pain in her kidney.  she is having this pain daily.  it has been so severe we have gone to ER only to be sent home because they give her a antibiotic for a UTI that they think is coming on.  Could she have something serious in her kidney?
