Sore Arm After COVID-19 Vaccine Could Indicate Serious Complication: Doctor

The arm pain is connected to heart-related conditions, which many experience after injecting the COVID vaccine.

Individuals who experience a sore arm after taking a COVID-19 shot may be at risk of facing cardiac issues, according to cardiologist Peter A. McCullough.

“I always ask patients if they had a sore arm or more severe reaction within the few days of the shot. It may be a harbinger of future cardiovascular serious adverse events, including myocarditis and sudden cardiac death,” Dr. McCullough said in an Oct. 27 Substack post. Myocarditis is an inflammation of a heart muscle called myocardium, which can reduce the heart’s ability to pump blood. Dr. McCullough cited a Sept. 19 study published in the Radiology journal, which states that 458 out of the 700 participants, or 65.4 percent, reported pain in the arm after COVID-19 vaccination.
