Good luck for your recovery! I really like the shoulder exercise videos you posted on youtube. My boyfriend (and up until this year, regular climbing partner) couldn't climb for 8 months this past year due to shoulder injury and eventually also had surgery when PT failed to make an improvement (impingement syndrome). I have since become more vigilent in trying to prevent a shoulder injury via rotater cuff strengthening exercises. Hopefully this stuff will help! Hope your head/hand/shoulder all heal quickly!
