A friend suffered with dermographism, then yellow jaundice, only to discover he was very, very low blood pressure, to even fainting, with very very low sodium. So do you believe that the low sodium may have brought on his dermographism, etc.?
He was drinking also a lot of Kangen water, which I believe could have washed out his electrolytes. Started adding sea salt, got him off the Kangen. WWW.WWWW.WW
