Thanks. I have an irrational fear of vaccines since I started getting the Covid vaccine. I have a reaction every time, when I've never had a reaction to any other vaccine. On top of that, I got PMR during Covid, but it came on slowly and took forever to get diagnosed, so I can't really say it was from the vaccine.

So is your understanding that it can happen and you're unaware? I guess that must be true, given that people get heart failure and never see it coming. My last echo appeared to show some diastolic dysfunction. Now I'm terrified of heart failure, partly because I just don't understand how it comes on or the timing of medical interventions. It seems like they wait until there is irreversible remodeling to actually start treating any potential causes. That seems odd to me.
