Abstract

The occurrence of an intramuscular mass accompanied by sleep-disturbing pain at the inoculation site lasting for 4 months after the coronavirus disease 2019 (COVID-19) vaccination is rare. A 68-year-old man, who had previously received multiple COVID-19 vaccinations without any issues, encountered the problem described above for the first time. After administering 200 mg of celecoxib and 10 mg of nortriptyline for 1 month, ultrasound assessment revealed that the mass volume was reduced by more than 50%, and the pain disappeared completely.
