Well, it came on gradually until I would have to go almost as soon as I finished and walked out of the bathroom. The stone was taking up a good portion of my bladder and putting pressure on it.
Your problem could be a different thing altogether than mine. I don't know about an overactive bladder, but I do know as we age we pee more often during the day. Do you get the feeling to go very badly only after you drink a lot of fluids?
She might be right about retaining water in his case, but yours is the opposite problem. I think I would see a urologist if I were you, just like I did when the bladder stone started working on me.
Let me know if you have any other questions.
