What surgery is it?  Dislocation, rotator cuff, etc?
I had my dislocation surgery in Philadelphia.  Everything went great.  The pain and initial recovery was way less than expected.  I kind of half-assed it with follow up PT.  As such, I lost quite a bit of strength in terms of weight lifting, etc.  Overall, though, it was quite successful.
Good luck in surgery tomorrow, 2021.
