Elliot,
yes I understand about getting stuck. I am there right now with the left knee and right leg. The knee needs replacement,but I'm going through the series of shots for the second time. The sciatic nerve in the other leg was damaged by a bulging disk, which has left the foot flop. So I get down and I can't get back up! LOL
So I saw the back doctor today and the knee doctor last week. If insurance keeps dragging there feet, I may die first! LOL
