KY Jon,
My best advice is to stay positive. I had a complete torn rotator cuff and a detached bicep. I'm right handed and it was my right shoulder. My surgeon said that he wasn't sure he could fix it. He is the head of shoulder surgery at the University of Rochester... here in NY...so he knows his stuff. My surgery lasted 5 hours and other than a flat bicep, and only about half of the muscle strength... I'm fine.... and you will be too. My wife, who is a recovery room nurse had me practicing using my left hand for everything for almost a month... good suggestion! It may sound funny... but even using the restroom was a challenge left handed. My surgery was 16 months ago... and I'm shooting my bow... shot sporting clays this past Wednesday... but I'm still recovering. You must be patient after surgery. It was very frustrating going through physical therapy the first few months... but be patient and take small steps. Good luck, and I'll keep you in my prayers. Keep us informed.
