Not trying to impede your recovery, but my physical rehab guy told me that when I’m comfortably seated in a chair, or on a couch, it is quite ok to put a pillow in your lap, ditch the sling, rest your arm there for just a little while. Of course I did not quite listen well enough = at 4 weeks I was gingerly picking blueberries in my garden, and at 4 months + 1 day ( I counted), I played my first tennis match with full overhead serve motion. And that was the worse shoulder. But, I was a young 60 then. VERY lousy serve! But, a serve. But to be realistic: 6 months will get you a long way, if you have been in shape before, and 9 months is about where I was 100% back to normal, even though I had full range of motion very early - the shoulder still had hitches, weaknesses, etc. Last surgery was about 9 years ago, 5 years before that. No trouble at all since then, and I do a lot of intense garden work, and try to swim 1/2 mile a few times a week. So that should maybe help currently hurting post-surgical patients to look ahead to a better tomorrow.
