Your child’s skin may be swollen, red, itchy, scaly, or bumpy. This dermatitis often results from touching an allergen such as poison ivy, items made from latex, such as balloons or toys, or nickel in jewelry, for example.
Another skin symptom is hives, which are raised welts that often itch. Hay fever, cat dander, insect bites, and some medicines are common causes of hives. If none of these triggers seems likely to be the cause, consider a food allergy, which sometimes manifests on the skin.
