I've had that on and off Legzz. If you get the urge to go, GO! Don't wait! Also, no hovering!! Drink lots of water and take some cranberry capsules twice a day. (These tips helped me a lot.)
I don't feel/or notice when my bladder is full sometimes. Try to pay attention to your bladder. (Right now mine is full so better get in there.)
I have self-cath supplies and I was unsuccessful in using them. DOH!! If you need to do it once in awhile, have a nurse train you!
