Is it possible that I was born too tall and got the muscles, ligaments, and tendons of some one 4 inches shorter? I have been practicing the hip stretches and openers daily but with little to no change. I don't think I canblame my prosthetic knee for this, even though I can usually find a way to make my knee responsible for anything from a flat tire to burnt toast.Hey! My step daughter just gave me a book by Erich Schiffmann for Christmas! You studied with him. (You already knew that part.) I like finding those types of connections. I hear some of you when I read his book.
