I say buy some sweat pants, easier to get on..

jk
I had both my shoulders operated on, but wasnt the rotator cuff. It was the bones sitting out on the ends of my shoulders. The gasket in between them has worn out and the bones were grining in to each other. They just shaved the bones back. So far so good!!
Hope you heal fast and make a speedy recovery. Remember it only hurts until it stops.
Good luck dwd!!!!
