  RE: [RC] Wither Question - Burnett, EllyThe 
reason for the white is because the skin cells are so damaged that they no 
longer have any pigment.  It's the same principle behind freeze branding of 
animals.  It gets very technical, but I do not believe the nerves are 
affected from this--the lack of color is because of damage to skin and hair 
follicles.  But the fact that there are white spots mean there is 
significant damage to at least the skin.
