Summary
Hives are a skin reaction characterized by red, itchy, and swollen bumps that occur when the body releases histamine. They can be triggered by various factors, including allergic reactions, temperature changes, stress, sunlight, insect bites, certain medications, and pet dander. Typically, hives are harmless and resolve within 24 hours, but if they persist or are widespread, consulting a dermatologist is recommended. Treatment options for mild cases include over-the-counter antihistamines and soothing lotions. Immediate medical attention is necessary if severe symptoms, such as difficulty swallowing or faintness, occur.

If you have a mild case of hives, it will likely go away in a few days. You can apply a soothing anti-itch lotion or cream and take an over-the-counter antihistamine such as Benadryl. If your hives last longer than a few days, cover a large area of your body, or are caused by an allergy, it is best to schedule an appointment with your local board-certified dermatologist. Please seek immediate emergent care if you are having problems swallowing, feeling faint, or experiencing swelling.
