Overview
Nickel allergy is a skin rash or irritation that occurs when you come into contact with nickel. This condition is a form of allergic contact dermatitis. Allergic contact dermatitis happens when your skin touches or comes near an ordinarily harmless substance. Nickel allergy is the most common type of contact dermatitis related to metal.
The skin rash from nickel allergy may be itchy or painful. Allergic contact dermatitis causes delayed reactions, so your symptoms may not appear for up to 72 hours after nickel exposure.
Nickel allergy can develop at any time. Once you have a nickel allergy, it never goes away. But you can treat it by avoiding nickel or using medications.
