LONG covid? COVID Pneumonia?

A new thing i've seen trending is people trying to state that covid causes myocarditis.

Pfizer gave half of their trial participants the vaccine, half got saline. They tracked side effects in both groups. No placebo participants got myocarditis, and a side note worth mentioning, none of the placebo group got Bells Palsy
I don't know either way. I do know the symptoms didn't show up until 5 months after getting vaxed, and 4 weeks after getting covid. Draw your own conclusion.
