HELLO, My 3 yr old daughter has had a uti for a couple of days and she has been on suprax. She had only one uti and that was a week or two ago. Today she pee'd and there was blood in her urine that dripped after she pee'd. She has been screaming and crying since wed and the drs have just told me to keep her on her meds and give her tylenol and motrin. Today they said to take her to the er because it may be more. What could it be?
