Hives

🌿 Overview

Hives are itchy, raised welts caused when the skin releases histamine, usually from an allergy or sensitivity. Most pass on their own; cool compresses, oatmeal baths, and avoiding the trigger help. Swelling of the lips, tongue, or throat, or trouble breathing, is an emergency.

Hives are raised, itchy welts that pop up on the skin, often quite suddenly. They can be small dots or large blotches, and they sometimes join together. A tell-tale sign is that each welt tends to come and go quickly — one may fade in minutes or hours while a new one appears nearby. Most outbreaks settle within a few hours to a few days. Hives happen when the skin releases a chemical called histamine, which makes tiny blood vessels leak fluid into the skin and raises those itchy bumps. The trigger is often an allergy or sensitivity — a food, a medicine, an insect sting, or contact with something the body doesn't like. Stress, heat, cold, and pressure on the skin can set them off too. Sometimes no clear cause is ever found, and that's common. Most hives are harmless and pass on their own. The goal is simply to calm the itch and, where you can, figure out and avoid the trigger. But there is one serious exception to watch for: if the lips, tongue, or throat swell or breathing becomes hard, that is an emergency.

Common signs

• Raised, red or skin-colored welts
• Strong itching
