>without feeling like my head lost all oxygen >brain fog, nerve pain, untriggered anxiety that all reminded me the time when i had anemia (for different than covid reason though), and reading symptoms described by others it all very similar to low oxygenation. I wonder if covid screws with oxygenation machinery - either lung function or in some anemic like way. >The most common reported symptom of long COVID is fatigue and the overall symptom picture resembles that of myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS), which is often triggered by a viral infection. There have been studies connecting the chronic fatigue syndrome to the post-viral infection rage of B-cells which may go for months https://www.discovermagazine.com/health/are-b-cells-to-blame-for-chronic-fatigue-syndrome https://www.discovermagazine.com/health/are-b-cells-to-blame... - in this and other similar studies they've used cancer (like methotrexate) and/or immune suppressing drugs to kill the B-cells.
