memory, cold hands/feet, spasms, vision issues

lots of people make mention of headaches cold feet and hands, spasms, memory, cognitive brain fog issues, vision issues, double to blurred. Well check out Hughes Syndrome symptoms. I remember some people getting a dx of thrombosis because of the thickness of ivig and what it does to the blood and in actuality it could be this and taken care of with blood thinners or even asprin. Funny thing is they use that Elisa test to check assays or a liquid phase coagulant to check assays and they check for anticardiolipin. It is often misdx as ms because of the neurological component. Just a thought.
