I'm sorry you had that experience with vaccines. I know it won't make much difference to you personally, but the truth is that these sorts of chest pains and heart problems are far more common in immune-naive people who are infected with covid than in people who get vaccines.
Could you drop a link to some research for side effects of immune-naive infection versus vaccine? I've read the latest on the Pfizer side effects but have nothing to compare it to for immune-naive infection effects and rate of those kinds of symptoms.
