The cortisone was probably injected into the shoulder collective, not the muscle, to help near inflammation there.
It is complicated to diagnose with the information provided, but within may be more going on here than a strain to the cuff.
I suggest you have your MD dispatch you to physical therapy for a full evaluation. The PT will look at the ligaments and muscles around the shoulder, and will determine what structures are given up the ghost properly. They can apply treatments that will help bring care of your short-term anguish, and also likely help out you to get historic the problem. PTs are also typically quite accurate at recognizing when your problem is out of their nouns, and will tell you to see an orthopedic surgeon.
Go to APTA.org, click on "find a PT", and flush your home area. You may want a consultant who is board-certified in any orthopedic or sports PT (OCS or SCS after their name).
Good luck!
It probably will continue to flare up at times. You should see an orthopedic specialist and possibly enjoy an MRI done.
