So, I ended up with a partially torn rotator cuff. On the whole, it's a little worse than what we were hoping for, but better than what it could have been. The partial tear has been repaired, and the bone spur has been removed. A full tear would have resulted in at least 4-6 months of recovery, but we're looking at hopefully just 6 weeks or so. I expect to still have some pain after that, while the bone heals where he shaved off the spur, but I am very hopeful of an eventual full recovery.
Until I am able to stitch and sew again, I will be doing a lot of surfing the web, looking at all of the progress everyone else is making, and cheering you all on.
