FWIW, I had frequent heart palpitations for a period of a few months. So far as I can tell, they seemed to commence around the time I got the second Pfizer shot (April 6) or shortly afterward. The palpitations stopped roughly a month ago.
I have no idea whether the shots and the palps were related, but I just thought I would throw it in there, considering that some younger people have reported cardiac inflammation related to the shots (I’m 54).
I think it’s important that you added your experience. There are people your age or older with heart inflammation and blood clots so there’s no point on proactively ruling out first hand observations. Thank you for contributing to FR’s knowledge base.
