My 15 year old suddenly developed eczema from out of nowhere. She has creams, lotions, anti-histemines and steroid creams from the doctor. She's constantly scratching though, and her arms and legs look like they have been scalded. When she tries to go in the bath or shower she ends up sobbing as it hurts so much. She says it feels like burning. As you can imagine with a 15 year old showering and bathing are important. She's very hygenic and before the eczema started would often have a shower in the morning and a bath at night. Now she can't bear being in water as it hurts and she's scratching her skin off literally. Any advice?
