My 12+ yr old girl was never sick until a month ago. Just completed 3 wks of antibiotics for cystitis with crystals. She's been dribbling urine for a month - initially it was continuous, but now she has some mostly continent periods, but needs a diaper overnight / if I'm at work and leaks when she naps during the day. Will this resolve or is it her new normal? Vet gave us amitryptaline to slow frequency / dribbling a week ago - but it hasn't appeared to help much.
