My wife had it. Its calcium paste buildup in the tube the tendon runs through. She had to have this paste sucked out with a needle after physio failed.
not really, it is a stiffening of the capsule of the shoulder. the recessus axillaris which stretches when you lift the arm is shortend when the shoulder is immobilized for a while. with pain meds and movement it gets better
