Yeah, I have "long Covid"...... and have had it for 6 years now, unfortunately. Well, not the swollen tongue, but basically the rest. It's horrible, and no, I don't have a diagnosis for it. Obviously it's not from Covid, which I also have had (twice). Perhaps it's from a previous virus I had, or even the flu vaccine which was forced on me in 2006. Maybe I've got MS? I may never know, since I can't get medical care right now, and the future is looking... weird at best.
