Allergies don’t just cause children to sneeze and wheeze. They can also show up on your child’s skin. A reaction may come in one of several forms.
At least 10% of children around the world have eczema. It’s especially common if your child has asthma, food allergies, or hay fever or if any of these conditions runs in the family.
Doctors aren’t totally sure what causes this skin condition. In infants, it shows up as a rash on the face or head. Later, it may spread to the arms and torso. The skin is often dry, itchy, and easily irritated. Symptoms can include:
A red rash
Scratching that damages the skin and leads to more itching
Thick, leathery patches that show up over time from scratching and rubbing; common areas include cheeks, creases of arms or legs, nape of neck, back, chest or abdomen.
Repeat skin infections that may be caused by scratching
The following things can set off more itching:
Certain soaps and detergents
Foods like eggs, nuts, cow milk, wheat, soy, and seafood, but only sometimes
When your child gets a rash after touching something he’s sensitive to, it’s called allergic contact dermatitis. Symptoms can include:
Skin redness or rash
Thick, scaly, leathery patches on the skin that develop over time
Things that can set off these reactions include:
Nickel, a metal in some earrings, snaps, and buttons
Poison ivy, oak, and sumac
Ingredients in mouthwash and toothpaste
Chemicals and dyes in shoes
Medicines used on the skin, such as neomycin (an antibiotic), antihistamines, and anesthetics (skin-numbing treatments)
Hives and Swelling
Hives are itchy red bumps or patches on the skin. They can last for a few minutes to a few hours and can come and go over a few days. Triggers include:
Foods like eggs, milk, peanuts, wheat, soy, seafood, nuts, and strawberries
Medicines, especially antibiotics
Insect bites and stings
Pet saliva or dander
Sometimes, hives can appear without a known trigger.
If your child has them, he may also get another kind of swelling called angioedema. It shows up on soft skin, like the kind around his mouth, eyes, and genitals. It usually doesn’t appear on its own without hives. Hives are not dangerous, but if you child has difficulty breathing or his tongue or throat have swelled, seek emergency medical help immediately.
