I've wondered the same since so much of the research written says 1-2 years and yours, much longer than my 2 years has to be so challenging. (Mine adds symptoms - over time - and becomes more debilitating.)

I think they do not know. I use a google alert for both some of the symptoms + Long COVID or other like term and find so many medical research that differs.

At "just" 5 years of the virus (which continues to mutate and infect) and now, especially in the US with funding dollars cut, we never know enough. I see so many long covid practices within teaching hospitals closing which does us no good nor for those who are still getting sick.

For now, because some treatments work for some and not all, some activities like yours triggers another round, or some, like mine, appear out of nowhere or so it seems.

On some days I am resigned to this for the rest of my life which at now 78 (and having just ended my consulting practice because of LC) may be lessened yet, each day I try so hard to be the me I was BC - before COVID.

To us all and to those who care to support us and the doctors who are committed to finding funds to continue research, hope.
