Rotor cuff surgery
Fordson; I’ve had three rotor cuff operations. All of them were quite painful.
They all required cortisone shots for pain management, and much orthopedic, and self-therapy.
I believe, your recovery, depends on you, and how hard you push yourself in your exercises, and self therapy.
Before my last operation my surgeon informed me, that I wouldn't regain much use of my arm, but the operation would alleviate, most of the pain. Nevertheless, through extensive exercise, I gained full recovery of my arm. It totally amazed my surgeon.
My methods might not work for everyone, but they certainly did for me. I still have near normal use of both arms.
