Go back to doctor : The symptoms of fever and back pain in a person being treated for a UTI is concerning for a kidney infection, called pyelonephritis. These can be very serious. You should see your doctor as soon as possible and this should not wait through the weekend.

Check urine culture: The bacteria maybe resistant to macrobid, a rare event but does occur. You may also have a kidney stone or a kidney infection. Given time a delay in treating an UTI may lead to infection reaching the kidney.
