I had rotator cuff surgery 2 years ago and my advice would be to take it easy for the time they want you to. Work hard at doing all of the physical therapy and in time it will get better. I was not able to sew for about 6 months and during that time I read, read, read. It took me a good year to be able to have arm movement that allowed me to put dishes in the cupboard. But it will turn out fine in the end.
