My daughter has complained off and on for about 12/18 months of stomach pains, it is now waking her during the night, she goes to the toilet normally, we have been to the doctor a couple of times, 1st prescribed lactulose , another has said she has a lot of gurgling and maybe some trapped gas, maybe to try her on a milk free diet , she has been following this diet for about a week/10 days and there has been no change, she was sent for a scan on her bladder after dificulty controlling her bladder she was prescribed a tablet to stop her bladder spasuming. her tummy ache remains even after we have her toiliting under controll?
