My dd is 27 months old and has eczema and an egg allergy. Her eczema has been quite bad for the last few months - very dry but no infection or anything. We have been having good results the last few weeks with Epaderm in a cool bath. This morning we went to the supermarket. When we got back I was getting the lunch ready when I noticed she had taken her trousers off and had been scratching her legs like mad. The back of one knee is really bad and looks like she reacted to something that made it really itchy and inflamed. She also has a few red lumps around her mouth. I gave her a dose of Zirtek and put her in a cool bath and her legs have calmed down. Should I see how it goes or take her to the doctor immediately just in case?
