Dieting and Eczema

I think my excema on my hands was triggered by using harsh detergents. I had a temporary job in a culinary field where I was constantly cleaning and sanitizing my equipment. Even after leaving this job, I still suffer, but not as bad. My hands crack, itch, and just plain hurt! They are embarrassing and I often try to hide them. I think I always had the tendency to get this because I have always had issues with my elbows, but now my hands are a major problem. I got some cream from a doctor and it has helped, but not completely. As for trying an "elimination" diet, I don't think I have the patience! On another one of these threads, someone suggested Noxema--using it like cream and not washing it off. (Apparantly, according to this person who posted, it was originally developed for this purpose! see the name"no xcema") I haven't tried it yet but I plan on buying some tomorrow and giving it a whirl.
