I had a episode about two years ago, thought I was getting Covid, had diarrhea and sore throat, then later in the Evening I thought a cold moved into chest. All this happen a few weeks after being put on blood pressure medicine, went to bed that evening, got up next morning early and me chest was still a bit sore. Called the doctors office and nurse wanted me to go to ER, so I went, good thing, my widow maker artery as they call it was 85% blocked. I’ve changed what I eat, use no salt, eat lots of fruit and no processed junk food. Lucky to have my wife take care of me as she does
