I've had this problem for many years (had kidney problems when i was younger) - I've started doing the excerises and it helps. But depending on how bad it is, they can take months (or even a year or more) to solve the problem.
I wear Tena liners - you don't even notice them, it's not like wearing a sanitary towel.
It can be worse for some women around a certain point in the menstruel cycle, by the way.
Glad I'm not the only person with this problem!
