DD came up in a really strange nettle sting type rash on Sunday, clusters of pale raised blotches and very red surrounding area. Dropped in to see a doctor and they gave her piriton and it went really quickly. It's flared up twice today. Yesterday it was on hands and face, today just hands and feet, but with one big white wheel stripe on the back of her arm. Sure it's an allergy, but NO idea what. Anyone had similar?
