I've had both shoulders worked on also.
The shoulders are so easy to tear it's a wonder more people don't have trouble.
I tore my left one the first time in 1995.
My left shoulder was operated on Oct 10 and the right Jan 3.
Got about 70% movement in left but little strength.
Almost no movement in the right yet.
Can't do hardly anything, including shooting, for some months yet.
Well, I'm happy because it looked to be worse and I think it will be OK in a few months.
I hope yours turns out as good as possible.
Think I'll try that sleeping thing again.
