I read too much FUD about the vaccines before my Moderna booster, particularly the myocarditis in younger men results. Started feeling tight chested and a lump in my throat later that day after the vaccine. Finally went to urgent care after a day or two and got an x-ray and EKG and it showed nothing of concern. Doctor suggested it was probably anxiety, suggested taking an NSAID and relaxing and I was better pretty soon after.
