### Nickel Allergy: What You Need to Know Nickel is a common cause of skin allergies because it is found in many everyday items such as jewelry, cell phones, coins, zippers, eyeglass frames, belt buckles, and keys. If you experience itching, redness, or a rash after contact with these items, you might be allergic to nickel. **Symptoms:** - Itching and redness - Rash and dry patches - Swelling of the skin - Blisters that may break and leave crusts and scales Symptoms usually appear 12 to 48 hours after contact with nickel. In severe cases, the rash can spread, and sweating can worsen the condition. If the skin becomes infected, it may become warm, redder, or filled with pus, requiring immediate medical attention. **Diagnosis:** A doctor can often diagnose a nickel allergy by examining your skin and asking about your contact with metal items. A dermatologist may also perform a skin patch test, where small amounts of nickel and other allergens are applied to your skin and covered with patches for 48 hours. If you are allergic, your skin will show a reaction. **Treatment:** - Avoid contact with nickel-containing items. - For mild symptoms, over-the-counter hydrocortisone cream and antihistamines may help. - For severe symptoms, a doctor may prescribe steroid creams or immune system drugs. - In very severe cases, oral steroids and antihistamine pills may be necessary. If your skin is cracked or blistered, remove any metal jewelry immediately and see a doctor to prevent infection. **Prevention Tips:** 1. Use sterile, surgical-grade stainless steel instruments for piercings or tattoos. Avoid piercing guns. 2. Choose jewelry made of surgical-grade stainless steel, 14-, 18-, or 24-karat yellow gold, pure sterling silver, copper, platinum, or titanium. Avoid white gold as it may contain nickel. 3. Opt for eyeglass frames made of titanium or plastic. 4. Select clothing with plastic or plastic-coated buttons, snaps, rivets, or fasteners. 5. Wear watchbands made of leather, cloth, or plastic. 6. If a piece of jewelry causes a reaction, consider having it plated in a less-allergic metal like platinum. 7. If extremely sensitive, avoid nickel-rich foods like mixed nuts and chocolate. By following these guidelines, you can manage and prevent nickel allergy symptoms effectively.
