Thank you for the link to the video. I learned a great deal from it. It makes sense that when you look at the symptoms that this could be due to vasodilatation, or vasculitis?
Also very interesting was the discussion regarding the nonclassical monocyte or antigen presenting cell has pieces of the spike protein (s1) which bind to the endothelium of blood vessels and causes inflammation through out the body due to the secretion of VEGF and TNFalpha.

To be honest I may need to watch the video again, there was a lot of information in it.
