So the at the latest visit (May 2), the nurse was going through the initial check up and my wife mentioned having lower back pain. Somehow this made them suspect an infection (the kidneys?) and they needed another cup sample, uh, the last one wasn’t full enough. So we ended up sitting around for a while while she drank cups of water(!). Eventually they got their sample and decided she did have a UTI. The doctor proscribed antibiotics that she’ll need to take twice a day.
