Sounds like you are where many of us have been. You absolutely must read up on cytokines / histamine involvement in long haul symptoms. This is really where it’s at for treatment and resolution. You need specifically to research the use of Zyrtec(citirizine) and Pecid(famotidine) for the symptoms you are having. Cured mine. Over the counter remedies that are working for many people. Itching cured. Other symptoms mellowing as cytokines are less expressive. The fatigue is the leftover symptom for high percentage of us. But you must get some movement/exercise in. I do it daily. Muscles waste and sap strength further. If you have a decent doctor who is willing to listen talk to him about the research. Or find another doctor. Take the supplements that have been found to help long haulers. I am miles ahead of where I was 2 1/2 years ago.
