My 5 year old daughter has asthma and has to use an inhaled steroid once every day. For the past week, she keeps saying that she has to pee and then she goes and as soon as she is done she thinks she has to urinate again. I took her to the doctor and everything looked normal - no infection - does anyone have any suggetions as to what might cause this? She has no infection but keeps thinking she still has to go after she is done.
