摘　　要：BACKGROUND After vaccination was mandated worldwide,various adverse effects associated with the coronavirus disease 2019(COVID-19)vaccination,including shoulder pain,have been reported.Here,we report a case of new-onset shoulder pain after BNT162b2(Comirnaty,Pfizer-BioNTech)mRNA vaccination.CASE SUMMARY A 50-year-old man visited our rehabilitation center with left shoulder range of motion(ROM)limitation that had persisted for more than 5 mo.The history included no specific noteworthy events,except vaccination.The pain in the patient’s left deltoid muscle appeared 1 day after the second BNT162b2 vaccination and intensified to severe pain.The patient self-administered aspirin,with which the pain subsided immediately,whereas ROM limitation persisted.At the first visit,the patient complained of dull pain and ROM restriction of the left shoulder(flexion 130°,abduction 110°,and external rotation 40°).Among the diagnostic studies conducted for the evaluation of the shoulder,magnetic resonance imaging showed a thickened coracohumeral ligament.Nerve conduction studies and needle electromyography showed no electrodiagnostic abnormalities.The patient received comprehensive rehabilitation for 7 mo and had an overall improvement in pain and ROM of the left shoulder.CONCLUSION In this case of severe shoulder pain after COVID-19 vaccination that subsided immediately with aspirin treatment,the exact cause and mechanism of pain are unclear.However,the clinical symptoms and diagnostic workups in our report suggest the possibility that the COVID-19 vaccination triggered an immunochemical response that resulted in shoulder pathology.
