Ever since I had covid 5 years ago, my body has been stuck under a constant firehouse shower. High heart rate, shortness of breath, and a constant pressure in my upper chest.

I know it's immune related, because when I am coming down with a cold the symptoms all vanish. Like the firehose has an actual fire to fight.

When you're sick your body releases all sorts of stuff that makes you super relaxed and force you to chill/rest, so might be completely unrelated

Which is in itself odd, as there's no obvious mechanism (at least in a developed nation inhabitant who typically have considerable fat reserves and ready availability of food) for the immune system to need resources which would be otherwise used by the muscles.

Like we can all feel the lack of "energy", but that energy isn't the same thing as actual calories, glycogen, blood O2 and so on. Presumably a lot of CFS conditions are relating to that biological switch - "you're ill, rest up!" - getting stuck in the "on" position, but AFAIK nobody has definitively found it despite a whole lot of looking.
