question: My 21 month Old son has suddenly come out in a really blotchy rash, I thought it was chicken pox at first as they started out as spots, now they are mostly massive red blotches, as though he has been hit with something or scalded.. it is not on his face, just his torso down? He also seems well in himself apart from last night he was screaming and crying for about 2 hours, but today he is fine.
