Cause of Eczema

What are some of the causes of eczema? I eat a clean diet, orgnic no proccessed foods, no sugar, caffiene or alchohol.I eat free range organic meats etc. and I am still having break outs on my feet. I use coconut oil on it and it helps. I drink plenty of fluids.... I think if I knew more about the causes of this I could help myself better. I would appreciate your help. Thanks!! Tweet
