It started last night and this morning looks really dramatic, on his face, back of neck, ears, arms and legs, but not on his chest or back.
Took him to rubbishy GP this morning, who said he doesn't know what it is, can we come back later and see him about 5pm to see what it looks like then.
DS doesn't have a temperature, seems fine in himself. He hasn't eaten anything he hasn't had before in the last few days. I was assuming an allergy would be pretty immediate. Doctor doesn't think slapped cheek because it's on his legs and arms.
Any ideas?
TIA
