Fingers (and toes) crossed that you don't have MGUS and instead something that is leaving. There is so much to learn. I have celiac because of H1N1 followed by high stress (and genetics). I got glutened last March the same day I was exposed to covid. Having covid during a cytokine storm was not fun. My long covid (LC) is almost gone. Vaccines do trigger our immune systems, and are they still on alert once the mRNA bits are gone? There are similarities between LC and some autoimmune diseases.
