Long-term management for chronic dry, irritated skin.
Allergic/Immune Rash

Allergic reactions (food, drugs, insect stings), infections, stress, or sometimes the cause remains unknown (idiopathic).
Keep a diary to identify and avoid specific triggers. Carry an EpiPen if you have severe known allergies.
Antihistamines are the first line of defense. Cold compresses can soothe the itch. Severe cases may need oral steroids.
Myth: Hives always mean you have a food allergy. Fact: Many acute hives cases are actually triggered by simple viral infections, especially in children.
If hives last more than 6 weeks (chronic hives) or are accompanied by lip/tongue swelling and breathing trouble (go to ER).
