My sister has a bone spur on her heel and it gives her a lot of trouble. I don't know whether she would be a candidate for surgery or not. I'd like to hear from other people who have had bone spurs removed to see if they got much relief.
Still, as much as it sometimes hurts her to walk, any improvement would probably be welcome. She hasn't found too many shoes that take the pressure off her heels that allow her to walk comfortably all the time, which is not good. She has insurance, so maybe she can get this taken care of before it gets much worse.
