My brother has been suffering ever since his first or second encounter with COVID, I forget which.
His resting heart rate was very elevated from before he got sick, and recovery rate quadrupled. Just walking up a flight of stairs or two would require him to sit down, winded, to recover.
After all sorts of fitness tests, heart monitoring, lung tests, etc, the best guess the doctors could come up with was nerve damage from the infection or subsequent inflammation.
He's gotten covid 4 times total now. I don't think there's any way to tell if he's just unlucky in getting exposed to it or if there is some mechanism that lets it hide in the body, though I suspect he's just unlucky.
