Re: OK, blew the Rt. sholder Rotator Cuff, now what?
After a bad motorcycle accident, I had two broken scapulas, broken left arm (both upper and lower), left shoulder torn labrum (pot handle tear), torn rotator, and grade3 AC separation in the right shoulder. In the beginning I couldn't even wipe my own ass...
For shooting, a bipod in prone (or shooting bench) is mandatory. After that, its truly whatever your pain tolerance can handle. Lifting a rifle is going to be practically impossible, but managing recoil really wont be a huge painful task. Main force is absorbed by the clavicle before your rotator would ever feel it. While using the shoulder will hurt in and of itself, the recoil should be manageable.
and as for recovery, DO NOT FUCKING DROP OUT OF PHYSICAL THERAPY!!!! Do EVERY day you can, even if you feel 100%. Range of motion is key to keeping the pain away, otherwise you'll just stiffen up and hurt more. If your doctor has not recommended it yet, get a prescription for "dynasplint". Google it. It looks and feels like a mid evil torture device, hurts like hell, but will get your range of motion where it needs to be. a month+ of using that was all I needed, and now my range of motion is equal to my other side.
Hope I could help, and good luck
