My rotator cuff was a year recovering also. I had a 10ga I wanted to shoot. The first time I tried it jumped up and hit me in the nose, hurt my nose and my shoulder. I had it ported and lengthened the stock. That helped a lot.
I liked to play tennis so I started playing left handed and did surprisingly well. Shooting left handed is something you might give thought to. The big thing is to give yourself recovery time. Everybody is different because one person has a quick recovery doesn't mean you will. Exercising in a swimming pool really speeded up my recovery.
