Not really answering your question, but after one of the boosters I had ~1 month of abnormal heartbeat and was hospitalized. My chest also felt uneasy, somewhat painful, and I could feel my heart double beating irregularly. Best answer I got was that the vaccine caused inflammation in my heart which caused that issue. Luckily it has since cleared up but I occasionally feel weird feeling in my chest. Could also be stress/anxiety
