Yesterday afternoon my 9 year old dd said that the back of her ear was sore and bumpy. There was a raised rash so applied some suncream and gave her antihistamine. Rash continued to spread and she has woken up with the rash behind both ears, on her face, neck, shoulders, arms. Nothing out of ordinary yesterday. No new washing tablets, food etc. Said she felt a little unwell yesterday. Fine in herself today. Any idea what this rash could be please? Will pop to see pharmacist this morning too. Thanks.
