Although it is a rare occurrence, there are documented cases of shoulder an arm pain that persist for months after a vaccination.
If a vaccination is given in the upper third of the deltoid, it is theoretically possible that the injection needle and injectate could reach the subdeltoid bursa and possibly result in a bursitis and induce an inflammatory response. It is possible that this is the explanation of your symptoms.
Your healthcare provider or an orthopaedic specialist could perform a focused physical examination and provide recommendations. The orthopaedic specialist could also review the MRI results, possible perform a steroid injection (to decrease the pain and inflammation), and possibly refer you to physical therapy to make sure that you do not loose too much strength and range of motion while your shoulder recovers.
There is an article that reports two cases and the article was published in the journal, Vaccine, in 2007.

Vaccination-related shoulder dysfunction.

We present two cases of shoulder pain and weakness following influenza and pneumococcal vaccine injections provided high into the deltoid muscle. Based on ultrasound measurements, we hypothesize that vaccine injected into the subdeltoid bursa caused a periarticular inflammatory response, subacromial bursitis, bicipital tendonitis and adhesive capsulitis. Resolution of symptoms followed corticosteroid injections to the subacromial space, bicipital tendon sheath and glenohumeral joint, followed by physical therapy. We conclude that the upper third of the deltoid muscle should not be used for vaccine injections, and the diagnosis of vaccination-related shoulder dysfunction should be considered in patients presenting with shoulder pain following a vaccination.

Thank you so much for the information!
The Orthopedic doctor did exam me and review the MRI and concluded that I did have severe inflammation. With this they administered a cortisone shot in the shoulder joint which has helped with the uncontrollable pain. I now do exercises for my arms to hopefully regain my range of motion. I'll know more in 6 weeks how the range of motion is improving.
What I appreciated about the Orthopedic doctor as he listened and commented on some persons do have complications with the flu shot. He didn't pass it off with the usual - No - the flu shot couldn't have caused this, when I know it did. I think if my problems were taken seriously early on by the other doctors it would not have become so severe. Thanks again!
