COVID-19 vaccination can trigger symptomatic calcific tendinitis in individuals with pre-existing asymptomatic shoulder conditions. This case highlights how vaccines may precipitate previously silent shoulder pathologies into painful conditions.
Area of Science:
- Orthopedics
- Immunology
- Radiology
Background:
- Shoulder pathology can present as symptomatic or asymptomatic.
- Calcific tendinitis is a common shoulder condition.
Observation:
- A 50-year-old male developed left shoulder pain 3 hours post-COVID-19 vaccination.
- Pain persisted for 3 days, prompting medical evaluation.
- Ultrasonography confirmed calcific tendinitis of the subscapularis tendon.
Findings:
- The COVID-19 vaccination precipitated symptomatic calcific tendinitis from a pre-existing asymptomatic state.
- This is the first reported case of vaccination-induced symptomatic calcific tendinitis.
Implications:
- Previously asymptomatic shoulder conditions may become symptomatic after vaccination.
- Consider vaccination as a potential trigger for new-onset shoulder pain.
- Further research is needed to understand the mechanism of vaccine-induced shoulder pathology.
