@wilcy I've had three back surgeries, along with numerous injections. I find I can walk longer when I'm on the treadmill. Holding on to something like the railing on a treadmill gives me much more stability. I can't walk much more than one block without pain. And part of my problem is my SI joint slipping out. I was scheduled for a surgery to have it screwed to my pelvic bone. I canceled that surgery and will hold off until I can no longer walk any distance without pain. I just have to pace myself.
