After being in the hospital, I developed Blood Clots in my arm (deep vein), my lung and had a kidney infarction last fall. I went to the ER for what turned out to be a Graves Disease diagnosis, but they treated my swelling with an IV, which I got Cellulitis from. Ended up in the Hospital for a week, with the clots, etc.. I was tested for blood clotting disorders and have been on blood thinners since Sept. Hospital reading first came back positive for Lupus Anticoagulant, then said it was a false positive. Protein C & S still testing low, but I do not know what that means exactly. Any reason one would just develope unexplained blood clots? Any relation of blood clots to the Graves?
