My 4 year girl is experiencing frequent urination two times in one hour during day time. She doesn't have any other symptoms like burning while peeing or discomfort. She is very playful now, sometimes she sweat around her neck very much. Recently she undergo an antibiotic (tax-o forth) course for 7 day and 5 day after we had another urine culture test which again was positive with e-coli bacteria. She has no fever for which uti couldn't be doubted by the doctor. Now some doctors advice for further investigation as renal scan or mnc, etc, while others say she is alright only with a overactive bladder. We are very very confused at present but it is true that she might look healthy but passing urine at hourly routine cannot be normal. Please help us.
