question: I have autoimmunity. I have a lupus like syndrome that I m still being worked up for. I was recently put on Plsquenil and am starting to feel better but still have occasional shortness of breath and a recent flare that caused phlebitis with bruising. I have vasculitis. Today I sneezed and a fibrous blood clot came out of my lungs. I m wondering if I should be concerned and what if anything I should do. I go to the dr a lot and don t want to go again for no reason.
