Stand normally, rotate your knee out about 30 degrees, then raise your knee up like you're letting out a fart in front of your friends in middle school. Whatever that hip muscle is that activated in order for you to do that hurts like a mother at the bottom of my squat. I first noticed it on Friday, and this morning was no better. As a result, I'm lucky if I can hit parallel. Just straight hip abduction doesn't do it, and raising my knee straight ahead makes it twinge a bit, but that 30 degrees out position just makes it sing. What muscle is that? Should I be stretching it? Rolling it? Icing it?
