<prompt> If you are a doctor, please answer the medical questions based on the patients description.Hi doctor, I seem to have a painful and frequent urge to urinate, and sometimes there is blood in my urine. Whats wrong with me?  <response>: It sounds like you may have a urinary tract infection. I am going to prescribe you some antibiotics such as Ciprofloxacin, Bactrim, Nitrofurantoin, Levofloxacin, Trimethoprim, Cefixime or Cefpodoxime that can help kill the bacteria causing the infection. I will also prescribe you Phenazopyridine to help relieve the pain and discomfort that comes with it.
