Unfortunately I have had to diagnose myself and keep repeating it to the Drs. I am currently dealing with an overactive immune response to inflammation. So from what I can find for indoor on Drs papers they write about PASC long Covid the body is trying to get locate what it knows is microscopic so to speak particles left of Covid19 and it keeps doing it over and over to the point it becomes overactive for some of us I have entire body inflammation right now I can't get any Dr in Maine to treat. They keep telling me it a my body gaining weight. Which I know the difference at 49yrs old between weight gain and inflammation especially since I spent 20 years in nursing .
