Had rotator cuff surgery at 49yrs of age. It hurt like hell for 4 months!
Had PT for 3 months & doc cut pain meds off at 3 months.
That forth month was still awful but gradually got better after that.
But...don't regret it. Shoulder is almost 100% but still careful with it coz am almost 59 now, no spring chicken.

Hope you are better very soon!!
