I didn't have the neuro event or symptoms, but the dinner plate and cardio helping sounds awfully familiar. As far as I know I did not contract COVID, however I was part of the early response team for isolation after travel for the US Military so was exposed on several occasions early on and could have been asymptomatic. My first vaccine was a non-event; the second fostered a reaction so bad I almost went to the hospital. 103F fever, rigor (shivering so bad you lock up), etc. for about 8 hours, then the fever broke and I recovered fine. I had an anxiety induced possible cardiac event about a year after that (March 22), but I went to the ER and there was no EKG evidence and no troponin. Was monitored for 12 hours to be sure. I have had a weird vertigo issue crop up; I actually managed to have exactly what causes it diagnosed! One of the inner ear canals has dropped it's output signal about 75%; no evidence to why the nerves were damaged. I am slowly adjusting. I have no idea if it's related.
