Ankles and Toes

A pain in the ankle or toe can stop you from moving, even though it is not the part you necessarily need, but the pain tends to radiate in all directions at once. The same is true of fingers and wrists, but they can at least be babied without having to park yourself in one spot and stay there. I think we need a parts store, a place to trade in the damaged joint and get a loaner while repairs or healing is done. Is anyone else interested in the possibility?
