Slapped cheek - does this sound lke it?

[Twiglett]

woke up one morning rather spotty cheek
next morning looked bright red

(aha methinks slapped cheek)

is now spotty again on both cheeks, torso and arms and is itchy

is that slapped cheek .. DS had it much milder ... no other symptoms but itchy rash

have given piriton and slathering on E45

hmm , could it be Scarlet Fever ? Slapped Cheek rash on body is more purple and lacy than spotty iirc

no fever though and tongue is clear
