Could you tell me why my leg turned itchy and red after in the snow?

Extreme: cold leads to constriction/narrowing of the small blood vessels which supply your skin...after this constriction and with the warming they DILATE causing increased flow a REDNESS and stretching of the nerve endings causing itching! Hope this helps Dr Z
