I have a friend with FD (Fibrous dysplasia) where her bone actually replaces itself with fibrous tissue ("scar-like (fibrous) tissue develops in place of normal bone" was the exact wording of wiki) and had her hip and part of her femur replaced at 23 because of it. every few years they go in and grind down any part of her bone that has started growing out of control.
So make sure it really is just a bone spur CHO
and Glitch don't be scared to go, because once you've been diagnosed with something you have the ability to treat and care for it, you cannot start treatment however if you don't go.
