I injured my rotator cuff last night when someone in my guard fell on top of me in exactly the wrong way. Lifting my arm up too much and holding up my laptop is enough to cause pain and discomfort. Relaxation and recovery are the all the doctor recommended but there's an upcoming tournament and time not spent learning is time wasted. How do you keep training? Laying down on my shoulder doesn't cause any problems so no hand drills (triangle, armbar, omaplata) and probably shrimping are on my list of to do... but I've heard about people like Draculino who injure their arms and roll using only the other one. Any video examples of this, or any tips and advice on how to do that?
