I had a bone spur irritating my rotator cuff. It was mildly annoying, but the doc was concerned it might eventially tear my cuff, if I didn't get it fixed. I had arthroscopic surgery, so not as evasive as regular rotator surgery.
Four weeks later I would say I'm 80%. Still is sore, worse than before the surgery
and my strength is still down. But it's getting better quickly. I hoping in another month, I will be better than new. Plus I'm 55, so I don't bounce back as quickly as you young guys.
