Urticaria

Hives (urticaria) are red, itchy, and raised welts on the skin that can appear suddenly and move around the body. They are usually temporary and can be caused by various triggers.

Treatment and Care Options
Treatment focuses on relieving itching, preventing flare-ups, and identifying triggers. Your doctor may recommend antihistamines (over the counter or prescription) to block the allergic reaction. For severe cases or swelling (angioedema), oral corticosteroids or epinephrine may be necessary. At home, cool compresses, colloidal oatmeal baths, and wearing loose-fitting clothing can provide significant relief. Keep a symptom diary to track potential triggers.

What Causes this Condition?

Hives, or urticaria, happen when your immune system reacts to something in your body. This reaction releases chemicals that cause blood vessels under the skin to leak, leading to itchy, raised welts.

Allergens: Common triggers include foods (like peanuts or shellfish), insect stings, medications, or latex.
Physical Stimuli: Some people develop hives from pressure (like tight clothing), heat, cold, or exercise.
Underlying Conditions: Sometimes, chronic hives can be related to thyroid issues, infections, or chronic stress.
