  As many as 10 to 15 percent of Americans suffer from a metal allergy. For these people, exposure to common metals, such as nickel, produces an allergic reaction. […] You may notice symptoms such as itchiness, dry patches, and blistery rashes. These are signs of nickel dermatitis caused by your body’s immune system overreacting to metal exposure. […] Metal allergy symptoms may include: Redness or other changes in skin color. Skin rash or bumps. Itching. Patches of dry skin. Blisters (in severe cases). […] In the case of a nickel contact allergy, symptoms may appear after your first exposure to nickel or after repeated contact with it. […] Once you’ve developed a reaction to nickel or another metal, your immune system will always be sensitive to it, causing reactions upon exposure.

• #2 Nickel Allergies Symptoms, Tests, and Treatment

  https://www.healthline.com/health/allergies/nickel

  Nickel allergies are increasing in the United States and can develop at any age. They’re more common in women and girls than men and boys. In the United States, about 36 percent of women under the age of 18 have a nickel allergy. […] People with a nickel allergy usually begin to develop a skin reaction 12 to 48 hours after coming into contact with an item containing nickel. The symptoms of a nickel allergy include: skin rash or bumps, redness or other changes in skin color, dry patches on the skin that resemble a burn, itching, blisters (in very severe cases). […] Someone with a nickel allergy almost always has a localized response following exposure to objects containing nickel. This means that the allergic reaction only affects the part of the skin that comes into contact with nickel. […] In rare cases, a nickel allergy can also lead to respiratory problems, including: runny nose, nasal inflammation, asthma, sneezing. […] The rash usually lasts from two to four weeks after exposure.

  A nickel allergy results in skin rash, itching and dry skin after exposure to nickel. Symptoms dont often appear right away. 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. Symptoms of nickel allergy range from mild to severe. They usually appear within 12 to 72 hours of coming into contact with nickel. Most people with nickel allergy only have a reaction on the part of their skin exposed to nickel. Common nickel allergy symptoms include: Bumpy skin (hives), Cracked skin, Itching or burning sensations, Patches of dry skin, Rash, Red or discolored skin. More serious nickel allergy symptoms (systemic nickel allergy syndrome) may occur if you eat foods that contain nickel or have a metal device implanted in your body. This can cause symptoms that affect your entire body. These symptoms may include: Blisters, Diarrhea, Fatigue, Headaches, Swelling. If you get a rash from a nickel allergy, it may last from two to four weeks. Nickel allergy usually isnt life-threatening. Because theres no cure, avoiding symptoms can be a lifelong challenge.

• #15 Nickel Allergy

  https://dermnetnz.org/topics/nickel-allergy

  Nickel allergy is one of the most common causes of contact allergic dermatitis. In affected individuals, dermatitis (also called eczema) develops in places where nickel-containing metal is touching the skin. […] The most common sites for nickel dermatitis are the earlobes (from earrings), the wrists (from a watch strap) and the lower abdomen (from a jeans stud); the affected areas become intensely itchy and may become red and blistered (acute dermatitis) or dry, thickened and pigmented (chronic dermatitis). […] Once this nickel allergy has developed, it persists for many years, often life-long. […] The degree of allergy varies. Some people develop dermatitis from even brief contact with nickel-containing items, while others break out only after many years of skin contact with nickel. […] Some people develop intermittent or persistent eczema on their hands and feet. It is usually a blistering type of eczema, known as pompholyx or dyshidrotic hand dermatitis. […] Unfortunately, desensitization with injections or pills is not possible so the allergy tends to persist long-term.

• #27 Nickel allergy – Wikipedia

  https://en.wikipedia.org/wiki/Nickel_allergy

  Nickel allergy often takes the form of nickel allergic contact dermatitis (Ni-ACD), a form of allergic contact dermatitis (ACD). Ni-ACD typically causes a rash that is red and itchy and that may be bumpy or scaly. The most common sign of nickel allergy is inflammation of the skin at an area that comes into regular contact with nickel. This often takes the form of a reddened patch of skin with raised bumps (papules) or small blisters (vesicles), and edema. People with chronic dermatitis tend to have dry, scaly, and cracked skin at the site of contact. These sites of inflammation (called „primary eruptions”) can occur anywhere on the skin that contacts nickel, but are most common on the hands, face, or anywhere that contacts metal objects such as jewelry or metal clothes buttons. Particularly high levels of nickel exposure can cause irritated patches of skin to appear at other sites on the body (called „secondary eruptions”). These typically occur as blistering rashes on the hands, eyelids, and at the inside of flexing joints (inside the elbow, back of the knee, etc.).

• #28 Nickel allergy – Wikipedia

  https://en.wikipedia.org/wiki/Nickel_allergy

  Nickel allergy results in a skin response after the skin comes in contact with an item that releases a large amount of nickel from its surface. The skin reaction can occur at the site of contact, or sometimes spread beyond to the rest of the body. Free (released) nickel that is able to penetrate the skin is taken up by scavenger (dendritic) cells and then presented to the immune system T-Cells. With each subsequent exposure to nickel these T cells become stimulated and duplicate themselves. With enough exposure to nickel, the amassing clones of T-cells reach „threshold” and the skin develops a rash. The rash can appear as acute, subacute, or chronic eczema-like skin patches, primarily at the site of contact with the nickel. From the time of exposure, the rash usually appears within 12-120 hours and can last for 3-4 weeks or for the continued duration of nickel contact/exposure.

• #29 Nickel allergy – Wikipedia

  https://en.wikipedia.org/wiki/Nickel_allergy

  Three simultaneous conditions must occur to trigger Ni-ACD: Direct skin contact with nickel-releasing item, prolonged skin contact with nickel-releasing item, and a sufficient amount of nickel is released and absorbed into the skin to cause a reaction. The pathophysiology is divided into induction elicitation phases. Induction is the critical phase (immunological event) when skin contact to nickel results in antigen presentation to the T cells, and T cell duplication (cloning) occurs. The determining factor in sensitization is exposure of significant amounts of „free nickel”. […] Nickel allergy is typically diagnosed by patch testing applying a patch with 2.5% (in North America) or 5% (in Europe) nickel sulfate to the upper back and looking for irritation on the skin. SNAS can often mimic IBS and may be more common than is widely appreciated. It therefore should be considered as a differential diagnosis item when a doctor is considering a diagnosis of IBS, and nickel allergy testing is advisable as a means to exclude or confirm SNAS.

  The overall prognosis for nickel allergy is excellent. […] A nickel allergy rarely causes significant complications unless the offending agent is left to irritate the patient continually or if the patient develops openings in the skin. The skin may become excoriated and broken, leading to an increased risk of infection. The skin breaks and infections can lead to the development of a superimposed infection (cellulitis). Cellulitis can complicate the treatment plan for the patient, and topical corticosteroids may limit the patient’s local immune response to fight the cellulitis. Treatment of the skin infection must be completed along with the removal of the offending agent to allow the skin to heal properly.

  Three simultaneous conditions must occur to trigger Ni-ACD: Direct skin contact with nickel-releasing item, prolonged skin contact with nickel-releasing item, and a sufficient amount of nickel is released and absorbed into the skin to cause a reaction. The pathophysiology is divided into induction elicitation phases. Induction is the critical phase (immunological event) when skin contact to nickel results in antigen presentation to the T cells, and T cell duplication (cloning) occurs. The determining factor in sensitization is exposure of significant amounts of „free nickel”. […] Nickel allergy is typically diagnosed by patch testing applying a patch with 2.5% (in North America) or 5% (in Europe) nickel sulfate to the upper back and looking for irritation on the skin. SNAS can often mimic IBS and may be more common than is widely appreciated. It therefore should be considered as a differential diagnosis item when a doctor is considering a diagnosis of IBS, and nickel allergy testing is advisable as a means to exclude or confirm SNAS.
