Hi my daughter had very dry flakey lips all over for 2 days after having a temperature and cold which she kept scratching. Yesterday she woke up with a red sore looking mark, she suffers from eczema too. Today is like the picture of her mouth from the side which looks like 2 cuts. Could this be a cold sore or just dry lips rash from scratching? She is 3. She has had no blisters or anything
