I had a similar surgery (subacromial decompression) where they shaved down the bone and cleaned out debris. Honestly, I was in so much pain before the surgery that it was almost a relief after surgery. I was only in a sling for a couple days, then started PT. In my case, I'd lost ROM before surgery. The PT helped me regain the ROM pretty quickly.
