It seems to me that there are an astounding number of long COVID cases, but doctors don't know what to do because there are, at this point, no definitive treatments for Long-COVID. W/o a treatment to offer, there isn't much the medical community can do. As research on Long-COVID continues, hope continues that there will someday be a treatment for it. I've had it since spring of 2023.
There does seem to be a genetic component involved, or at least a genetic component involved in who gets it. Both my daughter and I have had what was termed Chronic Fatigue long before the pandemic and then we both got COVID. She did not get Long-COVID, but I did. I am slowly recovering. I continue to have two main symptoms; I require 10 to 12 hours of sleep at night, and I can't smell or taste much of anything. Both symptoms are ones I can manage with.
Do take good care of yourself, get whatever help you and your family can afford. You have my very best wishes. No it isn't fair, I agree!
