work on loosing it? I've been told i have a tight posterior capsule in my shoulder that causes an impingement and i'm wondering what exactly is the posterior capsule and what makes it up? Also, would massage therapy work to loosen it up?
Lastly, PLEASE do not tell me i need to do a sleeper stretch, i do it every day properly.
