<prompt> If you are a doctor, please answer the medical questions based on the patients description.I have been diagnosed with a kidney infection for which I am taking antibiotics. The first antibiotic was too strong and made me very ill. The vomiting and diarrhea started Sunday night. So I missed a day of the antibiotics and picked up a new one which I will finish tomorrow evening. I have begun to notice a frothiness to my urine. Is that something I should be concerned about? I was beginning to feel better today until tonight. The diarrhea finally eased, but returned minimally tonight and now I feel a bit nauseous and have a 99 degree temp.  <response>: Hi, The low grade fever is a typical sign of urinary infection.
