In February 2016, I had a snowboarding fall where I hurt my shoulder.  I had a similar feeling in 1999 doing BJJ, which I figure tore it a little bit, then this snowboarding incident tore it wide open.  This was the weekend of Crossfit Open 16.1.  Did I still do the open?  Of course I did.  What an idiot.  Anyways, since then I have been having instability w/ my shoulder in overhead positions, and when I am hanging from the bar and become fatigued, I feel my shoulder ‘give’ as if the ball comes out of the socket.  I went to see the doctor who lined me up w/ some PT, so I did that, along w/ a lot of rest for the better part of six months.  I start getting back into working out, and come to find, the injury still hasn’t healed.  I still feel unstable overhead and again, when fatigued on the bar, my shoulder would ‘give’, causing me to have to drop off.  So I went in to the doctor again, and this time was sent to a shoulder specialist for x-rays and an MRI.  The results show that I have a 360 degree labrum tear. I have scheduled surgery for 11/15/17.  I have several questions for the community.  First off, are my chances of full recovery good?  My doctor is very optimistic and confident he can fix me up to reach my full potential, of course w/ diligent PT.  Also, are there upper body exercises and stretches I can still do, that will not cause any further damage and better prepare me for the surgery?  Are there things I should stay away from (i.e. anything hanging from a bar)?  I’m nervous, since it’s a 360 degree tear, that I may require a bicep tenodisis, and if I don’t yet, I wouldn’t want to damage it further to then require that procedure.  I purchased Crossover Symmetry during all of this too, so have been keeping that up regularly.  Any advice, experience and/or success stories would be greatly appreciated.
