My wife is complaining of a feeling that her bladder is full all the time, had yellow stools and discomfort/aches in the lower tummy. Any thoughts?

Bladder full always. We need more history to advice. Does she have to run to the bath room to pee, does she have urgency to pee, does it hurt, is she able to empty her bladder. There are many possibilities obsruction in passage of urine to overactive bladder syndrome. Se should see her doctor or a urologist, she may need urine test and some imaging of her kidneys and bladder.
