Charlie,
Whatever you do, ASK and LEARN what you can and can NOT DO! As we age, it takes time to heal... and if you but do one stupid thing, you can UNDO all the doc did in surgery with rotator repair.
It'll make you sit up and take notice when the PT starts to move the bad boy after it's been immobilized, but Son, you've been thru worse! Then it starts getting easier.
I made sure my surgeon drew graphic lines about what was "pain" and what was injuring his work!
After that, I endured the pain, healed faster than most, but never crossed that line of "don't do this!"
Keep the Son in your eyes!
