Last night my partner called 911 for an ambulance for me because I was having pretty bad intermittent chest pain that felt like indigestion. It didn’t go away with 3 Tums. I got a complete workup and was sent home 3 hours later without a diagnosis.
I slept soundly that night and have had no further chest pain since.
Did you let the ER doctor know that you recently received the covid vaccine? I don’t know if chest pain or indigestion could be a possible side effect or not.
