Ouch. I'm in solidarity with kirkman and everyone else that hopes you heal well, and that we get to see this project finished one day.
On a side note; I thought the same about an injury in my right shoulder from a few years back. It turned out to be a SLAP tear instead, but limited the use of my right arm nonetheless (persistent deep burning aches and sharp 'referred pains' that typically were felt in my tricep and elbow). Anyway, I hope you can find a decent surgeon. I walked out on three before settling on the one that ultimately fixed me up. He did such a good job that it now works better than my left shoulder.
