Hi there Barney!
Yes-it's not uncommon to have bladder problems,and these can come and go from day to day.
I find that mine can be caused by stress and the bladder not even releasing each time-so it's nothing unusual.
My Consultant give me medication to try and stop the flow,but it gave me all sorts of problems with urinating-and I stopped taking them.
CONFIDENCE helps a lot and I've worn nappies to give this-especially if I'm going on a long journey by car-and I've stayed dry all day knowing it didn't matter if I wet or not. Inconinence issdues can be extremly embarrassing and I often find it's easier talking guy to guy about problems and solutions.
Best of luck and please get back if I can be of any more assistance..
