I had shoulder surgery; same shoulder twice. When they tell you to move it further in PT even though it hurts, move it further. Otherwise it gets bound back up with scar tissue and they have to go in again. The doc told me that as soon as I was zonked out (technically not anesthesia, but same difference) for that second surgery, he moved my arm through full range of motion, snapping scar tissue as he went. Then he went in and cleaned it up. You really don't want that.
They have a local that is in a little ball they put in your bandage that will be slowly administered for the worst of it.
If I go through something like that again, I will be up front about concerns and get a low number of doses of the "mid grade" stuff. The gave me a few doses of high grade, a fair number of mid grade and a bunch of lower grade pain killers so that I would have what I needed depending on the pain level. That little candy store was completely used up a lot sooner than it should have been. Even the lower grade pills provided a buzz going a little over the specified max with a malt liquor kicker.
The shoulder surgeries and the knee surgery that preceded them are what really wet my whistle for opioids. Tread cautiously.
