“Explaining dermatitis as a rash would be helpful.”
“I don't know the difference between dermatitis and eczema so I assume you are expecting us to have paid a visit to a doctor.”
“The questions on dermatitis, eczema, dry and itchy skin, I would like more information to help me answer these.”
These terms are interchangeable. “Dermatitis” and “Eczema” are the names of skin conditions, whilst the “dryness, itchy, redness” are the symptoms of these conditions. Many of these skin conditions, especially in children are driven by foods.
