T.F.
My husband had a bad car accident which messed up his rotator cuff. Our Dr's prefer rehab over surgery. My hubby was in intensive care 48 hrs then started rehab before leaving the hospital. This was 17 yrs ago.
He never had to have the surgery because he was so focused on rehab and avoiding surgery.
He has the elastic pulleys he still used today when it acts up. He was at pro golfer level when this accident happened and he's back to his pro level if golf. By pro, I mean he went to college on a golf scholarship and has played with some if the best pro players on the tour today.
He'd tell you to opt for rehab ( physical therapy) over any shot or surgery
Best wishes
