I've had two foot suregeries. First to take out a bone chip that caused permanent damage to the subtalar joint. My doctor said it used to be called a shepard's fracture? It took over a year to find the problem. it was about the size of a walnut. As that was healing I tore a ligament near the same spot. I had surgery last July for that. I'm still in almost constant pain and the ankle gives out a few time a week. I can't walk around a lot or I won't be able to walk at all the next day. Did it not heal right? or is all of this cause by the damage to the joint; which I'm told is non-fixable?
