(to @gregorb)
We are both on the same timeline in terms of having LC. I had been on top of my vaccinations, but somehow came down with if for the first time last June.
I did NOT take Paxlovid, and you probably shouldn't undervalue it if it did indeed keep you out of the hospital. My acute Covid was quite mild.
However, and I had half-expected this, it did indeed transform into LC. My expectation was due to my previous encounter with CFS in the early 90's (and note that "CFS" is a separate Syndrome, that is, not merely a symptom as many of us experience it with LC).
Having parenthetically said that, I DO indeed think that CFS and LC might be largely the same phenomenon since they share so many (baffling) traits.
In my case, back then, as a young, strapping lad in my mid-40's, it hung around for close to two years, then finally lifted of its own accord. Perhaps I'm being overly optimistic, but I'm thinking, since this time around it feels pretty much identical (like you, I believe, pretty much confined to chronic fatigue), that it likely will just go away in hopefully not too much time. Of course, now I'm somewhat less young, and possibly a little less strapping, so maybe I'm being overly-optimistic, as unlikely as that would be given my otherwise curmudgeonly personality.
So the upshot is don't rush to any overly-dire conclusions Nobody can say it's "permanent"! Fight, fight, fight!
There's much that is still unknown about this syndrome/disease, despite DECADES of research with CFS ,and no less that a BILLION dollars of LC grant money that has been allocated in the U.S. (although much of that may well be clawed back by the Administration in the hopes of giving the .01% much-needed tax breaks...)
But perhaps I'm straying off-topic. Should I start a new thread? Like one about how these diseases are actually related to UFO abductions?

stay tuned, and stay well (as possible)
