Causes

Allergic reactions (food, drugs, insect stings), infections, stress, or sometimes the cause remains unknown (idiopathic).

Prevention

Keep a diary to identify and avoid specific triggers. Carry an EpiPen if you have severe known allergies.

Treatment Options

Antihistamines are the first line of defense. Cold compresses can soothe the itch. Severe cases may need oral steroids.

Myths vs. Facts

Myth: Hives always mean you have a food allergy. Fact: Many acute hives cases are actually triggered by simple viral infections, especially in children.

When to See a Dermatologist

If hives last more than 6 weeks (chronic hives) or are accompanied by lip/tongue swelling and breathing trouble (go to ER).
