Can you develope eczema?

I have never had problems with dry skin in my life by my skin is so dry lately it's cracked and peeling. I am constantly covering myself in lotion but it doesn't help, I mean it does for the moment, it's soothing but it doesn't help the problem. Does anyone know what kind of soap I can use that's for sensitive skin? And what lotion is best? 
My neck, ears, back, hands and chest are all so dry it's miserable. I have never had problems with dry skin in my life and now all the sudden it's become this huge problem.
