When I visited with the MS specialist, I mentioned my odd angioedema - whenever I got an injury to the face (usually either the dog bumping me in the lip, or biting my
tongue)
and the phlebitis in my leg. I also talked about the blood clot I had just recovered from. She went ahead and got a test for lupus anticoagulant, which was positive.
Now, those people who test positive for the lupus anticoagulant don't necessarily have lupus.
