I could have written this. I,too, had Covid before it was well known. Later took the vaccine and had additional flare up. Now I’ve had post Covid for over two years. Currently the thing that is driving me crazy is the phlegm. It never ever goes away. I clear my throat almost constantly. I get so fatigued I can hardly sit up at times. It’s so bad after I eat that I dread eating but still gain weight. I won’t go on and on, although I could! My oxygen level becomes so low at times I have to rush to the oxygen. My doctor put me on home oxygen now.
There has to be an answer for this.
