@jenniferhunter I noticed in the Mayo Clinic patient portal that my left shoulder MRI w/contrast and cervical spine CT scan has been read/interpreted by their radiologists. Below is what the reports noted. Doesn't really give me any answers as to what is still going on with the left shoulder. The C5-C6 stuff noted is right-sided and if I recall correctly, is pretty much what was noted in a pre-op report. I am still waiting to get scheduled for that guided bursa injection. I am sure COVID-19 has caused a backlog at the pain management clinic that will be doing it. Not sure what to think anymore.
Mayo Clinic impression of CT scan of cervical spine
-Interval postop changes related to anterior plate-screw and interbody fusion C4-6.
-Straightening of lordotic curvature.
-C5-6 right-sided uncovertebral hypertrophy contributes to moderate right foraminal narrowing.
-Otherwise unremarkable.

Mayo Clinic impression of CT scan of cervical spine
-Previously described articular sided fraying of the distal supraspinatus and infraspinatus tendons is less conspicuous on today's examination.
-No discrete rotator cuff tendon tear.
-Muscles of the rotator cuff remain normal in signal and bulk.
-Trace degenerative arthritis of the acromioclavicular joint.
-There is slight lateral downsloping of the acromion.
-Trace subacromial/subdeltoid bursopathy, which is similar to prior exam.
-There is new glenohumeral joint synovitis, which is primarily within the subscapularis
and axillary recesses.
-Latrogenic contrast within the subcoracoid bursa the extending medially within and along the subscapularis muscle.
-Minimal degenerative type undersurface fraying of the superior and posterior superior
glenoid labrum without discrete linear tear or paralabral cyst.
-Long head biceps tendon is intact.
-No abnormal stress reaction or fracture about the shoulder.
-No abnormal soft tissue masses.
