Trembow-
Didn't have shoulder surgery, but do share your pain. Three years ago when I started bowhunting for the first time, I didn't know how to pull a bow back properly. When I did so incorrectly I actually severed 2 muscles in my shoulder because I tried to pull 65 pounds straight back using only my shoulder muscle. During the time I heard a pop but thought ah what the hell. After deer hunting all fall, I went in to the DR after 5 months of not being able to really utilize my arm properly when I went in they said I had severed two of the three main muscles connecting your shoulder to your arm. I spent 3 months in rehab, and then was shooting my bow that summer. I did not have to have surgery but did have to do a lot of strength exercises in order to get it back to where it should be. Good luck hope the surgery goes smoothly.
