Having uti symptoms for ovet 2 weeks already. now after culture my dr perscribed macrobid. but already having lover back pain and side pain. ?

Start antibiotic.: Whether your UTI is just in the bladder or has now involved the kidneys, the antibiotic choices are generally the same, and MacroBid is generally a good choice. The only difference may be the duration - two weeks for a kidney infection versus three for a bladder infection. So start the antibiotic and follow up with your doctor in a few days to make sure you're improving.
