Hello,
Yes it is a it worrying when the catheter is removed & then use the pads to help control the leakage, my hospital provided 2 boxes of pads, and a box of pants free, mind you I handed back a box & a half back to them as I didn't need them after about a month.
Pelvic exercise is a must to get back control of your bladder, it's hard at first but persevere and it can be achieved .
Plan your days out, for instance go to the loo before travelling anywhere , when you arrived look for toilets and make a mental note of where they are for emergency .
Best of Luck
James
