A more severe form is systemic nickel allergy syndrome (SNAS), which is clinically characterized by cutaneous manifestations (such as contact dermatitis, pompholyx, hand dermatitis, dyshydrosis, and urticaria), a long-term course, and systemic symptoms (such as headache, asthenia, itching, and gastrointestinal disorders related to histopathologic alterations of gastrointestinal mucosa, borderline with celiac disease).
As with other allergies, nickel allergy develops when your immune system views nickel as a harmful, rather than harmless substance. Normally, your immune system only reacts to protect your body against bacteria, viruses or toxic substances.
