I've got fatigue and brain fog and my whole body hurts the next few days to weeks when I dare to do something mildly exhausting (like cooking pasta, showering, filling out long forms). I'm vaccinated, got two or three shots.

Nobody knows what the cause is. It seems to be the same as CFS/ME. Just with more cases because almost everyone on earth got infected.

Rest makes me feel better. But it takes time. With any luck I'll soon be joining a study on the effects of apharesis. And with any more luck it works and I won't be getting the placebo.
