Hello fighting4joy,
It is nothing to worry about and certainly not serious.............
SHELTON........
"Skin Crises: Skin eruptions may cover the whole body. (I have had but one such case in my own practice), or they may be only local. The eruption usually itches. One case in my practice was that of a woman who developed a solid mass of urticarial eruptions on both forearms, from hand to elbow. One arm itched intensely, the other itched not at all. Such eruptions may last but a few hours but usually they persist for from three to four days. They are processes of elimination". http://www.soilandhealth.org/02/0201hyglibcat/020127shelton.III/020127.ch28.htm
Put your mind at rest: the rash may last a few days or up to a week but is only evidence of impurities being expelled by the skin..........alongside other functions, the skin is also an organ of elimination too.
