Not after covid, maybe because I already have a collection of autoimmune diseases. After catching H1N1 flu 14 years ago it triggered celiac disease. I was probably gluten intolerant for decades, but that kicked it into avoiding celiac. Symptoms with autoimmune diseases can be single to many, and easy or difficult Mine pre-diagnosis were mostly enlarged lymph nodes, skin rashes, GERD, and GI problems (all went away GF). The polyneuropathy and collagenous colitis came later. Viruses and bacteria can trigger various autoimmune diseases. Hopefully you will get a diagnosis, treatment, and will be able to heal.
