Eczema is caused by a lack of Vitamin E and dry skin. Avoid pool water. Always mtsuoirize. My index finger has eczema too. I used to have it inside my elbows and other fingers. But they are all gone. Use steroid creams (prescribed by your doctor of course). Try shea butter for your skin. Use lotion with oatmeal. Use Ucerin cream for your hands. Do not let them stay dry. Eczema usually show up in joints (inside elbows and knees) and palm of hands (mostly fingers) and maybe feet. Use Aveeno cream (it has oatmeal formula). Hope this helps. It is not curable (Im mad about that). It's usually seasonal (usually summer for me). Might be winter for you. It's treatable by using the steps above. Good luck!
