Well, continue with the kegel. I had 3 operations. 1973 for Prostate. Believe it or not, that wasn't a big deal, and the incontanence was occasonal, mostly by careless.
Then a full-out ICU life-support. 2013. Kegels seemed to help, and it took longer. This time, had to use the second-lowest pads. - over 8 monrths.
The third was brain cancer, 2 tumors. They removed one, not the other. Said it was benign. Came out of there with full-blown incontanence. Add the I had leg-swelling so bad it looked like ballons that would burst if you used a pin. But, the right side was almost normal, a couple months later - the left wasn't going to exlode. Getting the legs fixed (The docs did not do anything and didn't care about the swelling) reduce the incontanence quite a bit, used the high pads for awhile. It took about down to the next-to-lowest pads, third up if I was doing hard physical labor. There were days where I needed to replace one. That was about 6 months. Now I'm down to #2 pads, exercise are have to change them out. If I'm I'm careful, what i eat and drink, can sleep without a pad.
The point? Kegels work - not for everyone and not perfectly and not nessicarily at the same speed. It can take different amounts of time for different people and circumstances. Watch liquids - soda isn't a good idea, and caffine after about 2 in the afternoon. Sucrolos (Non-sugar in some sodas, etc) means I might as well not try to sleep - i have to pee so often. It didn't used to do that, so keep track of food and drink. So people have to cut down in sugar.
Good luck. Keep trying.
