You might have one leg longer than the other. That can cause all sorts of things to go wrong. My feet problems started after I ruptured a disc in my lower back. I think it changed the way I walked slightly and then my feet gave out. I've worn orthothics for years and, for me, they help. That old song about the hip bone is connected to the leg bone is really true. Hurt one part and the problems radiate. I find it helps to never wear flat shoes. I need at least an inch rise in the heel. I have an aunt who had surgery and she was off work for a few months. This was quite a few years ago, so the surgery has probably changed for the better. But expect a fairly long recuperation if you end up going that route. And as as Marilyn said, get more opinions. I wish you well. It can be so frustrating when you have to make suggestions to the doctors. And still nothing helps.
