Nickel Allergy and Diet - the link to hand eczema
Nickel allergy (allergic contact dermatitis to nickel), has always been thought of as a rash that is isolated to the area where nickel makes contact with the skin. However, new evidence is showing that nickel which is ingested in the diet can cause systemic contact dermatitis (a rash other than where the nickel makes contact).
In an article recently published in the Journal of Clinical and Aesthetic Dermatology, Drs. Matthew Zirwas and Matthew Molenda, Ohio State University examined three different cases where individuals with nickel allergy also had generalized itching especially on their hands and feet. When the individuals were placed on a low nickel diet, their nickel allergy and generalized itching cleared.

Nickel allergic individuals should consider a low nickel diet if they have either hand dermatitis or a nonspecific, pruritic dermatitis (rash that itches).
Additional recommendations to avoid nickel in your diet:
