My dad fell and landed HARD on his left foot. All his weight went to the back of his heel. He now can’t walk on his foot. He thinks he may have bruised his heel, I think he may have broken something. All the information I’ve found about bruised heels have to do with runners and pounding force makes bruises eventually. I just want to know if by fall so hard on his heel, could it have only bruised it? I know its hard to say without seeing anything, but I just wanted to know the possible damages that could be wrong. Thank you.
