HIVES / URTICARIA
- Urticaria (hives) are red, itchy, raised areas of the skin that can range in size and appear anywhere on your body. Most cases of hives are known as acute and go away within a few days or weeks, but some people suffer from chronic hives with symptoms that come and go for several months or years.
- Hives can be an allergic reaction to medications, foods or insect bites. Hives can also result from non-allergic causes such as heat or exercise. Viral or bacterial infections can also trigger acute hives.
- If the cause can be identified, you should avoid that trigger. However, the majority of chronic cases are not related to allergy.
- Treatment of hives is often successful with oral antihistamines that control the itch and recurrence of the rash. Severe flare-ups may require taking corticosteroids to reduce inflammation.
- Atopic dermatitis (eczema) is a scaly, itchy rash that often affects the face, elbows and knees.
- Eczema is a chronic skin condition that usually begins in infancy or early childhood and can be associated with food allergy, allergic rhinitis and asthma.
- If you are allergic to certain foods, it can trigger eczema, especially in young children. Bacterial skin infections can cause flare-ups in children as well. Other potential triggers include animal dander, dust mites, sweating, or contact with irritants like wool or soap.
