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
- Dry skin
- 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:
- Dry air
- Rough fabrics
- Certain soaps and detergents
- Foods like eggs, nuts, cow milk, wheat, soy, and seafood, but only sometimes
- Severe itching
- Skin redness or rash
- Thick, scaly, leathery patches on the skin that develop over time
Things that can set off these reactions include:
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
- Viral infections
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.
