Symptoms

An allergic reaction (contact dermatitis) usually begins within hours to days after exposure to nickel. The reaction may last as long as 2 to 4 weeks. The reaction tends to occur only where your skin came into contact with nickel, but sometimes may appear in other places on your body.

Nickel allergy signs and symptoms include:

• Rash or bumps on the skin
• Itching, which may be severe
• Redness or changes in skin color
• Dry patches of skin that may resemble a burn
• Blisters and draining fluid in severe cases

When to see a doctor

If you have a skin rash and don't know how you got it, talk to your doctor. If you've already been diagnosed with nickel allergy and are sure you're reacting to nickel exposure, use the over-the-counter treatments and home remedies your doctor has previously recommended.

However, if these treatments don't help, call your doctor. If you think the area may have become infected, see your doctor right away. Signs and symptoms that might indicate an infection include:

• Increased redness
• Warmth
• Pus in the affected area
• Pain
