If your feet are numb, you have decreased your balance drastically. Your feet need to know their function to give you balance. If you can't feel them, are you standing? Does a tree in the woods make noise? There is a disconnect to the brain, so you have to retrain the brain to know you are standing. You also could start to lose some muscle tone, so doing exercises for your ankles and legs are a good idea. It's like if you can't see, your other senses come forward. There are some medications that slow the process, but it will continue to progress. I agree with NJEd, "We need to do what we can do, perhaps differently and try not to concentrate so much on what we can't do." A positive attitude goes a long way vs. poor me.
