Hi, Thanks for asking. Based on your query, my opinion is as follows. 1. Possible bladder inflammation or infection. 2. Get a cystocopy done to rule out any bladder cause. Avoid taking too much fluids during night. 3. Back problems with pressure on bladder could cause. Improve your back with muscle strengthening exercises. Also pelvic exercises will be helpful along with bladder training. Hope it helps. Any further queries, happy to help again.
