I had a high ANA titer when I got sick in June of 2022. I had COVID in January of 2022 and March of 2022 but felt fine after until June. It is long COVID, at least for me. I was also referred to an RA specialist, but do not have RA. This virus mimics so many other autoimmune diseases and I have run through the gambit of different symptoms. Keep a log of your symptoms and read as much as you can about Long COVID. The doctors, sometimes are not aware or do not really know how to treat it yet. Mine is treating symptoms. Hang in there. There are a lot of people in this group and I would also join the Long COVID group on this site as well. You can read the discussions that have taken place over the last year or so. Lots of information and suggestions.
