                        Ethel, I noticed the term VASCULITIS while I was researching a problem called ' urticaria / angioedema'.  The word is frequently used with this rash and swelling disorder.  It has to do with inflammation of blood vessels.  So far this is all I can tell you.  Anything else I definitely will tell you.
