A 74-year-old man developed acute atraumatic left shoulder pain and limited range of motion (ROM) 3 days after COVID-19 vaccination in the left deltoid. Physical exam revealed subacromial region tenderness, severely limited ROM (active and passive), weakness (drop arm, abduction strength 3/5, including on breakaway weakness testing), and impingement signs. Due to weakness and marked ROM limitation, a shoulder MRI was obtained to rule out full thickness rotator cuff tear and adhesive capsulitis, respectively. MRI showed extensive subacromial and subdeltoid bursitis (Fig. 1). The patient opted for subacromial space corticosteroid injection and physical therapy (PT). At the initial PT appointment 4 weeks after injection, he had full strength, near-full ROM, and had resumed his usual activities with minimal pain. Given the rapid improvement, we suspect the initial weakness and limited ROM were related to severe pain.
