This is exactly what happened to me. Coming on 2 years now, but ended up with diagnosis of APS after having PE & DVT (lupus anticoagulant antibody), and after all the testing, linked to Covid/vaccine in my case. I have to be on blood thinner now for life, and just recently was also diagnosed with Sjögren’s syndrome. It has been 1.5 years of chronic pain and trying to find answers. Advocating and researching led me to look past just my hematologist/vascular specialist to get a rheumatologist for testing around the continued pain and symptoms. Will be starting Plaquenil now. @cheart0405, I definitely recommend getting extensive antibody testing.
