When you break out in hives, you want relief fast.
This common skin reaction is characterized by itchy bumps or raised, swollen patches. Fortunately, hives are usually harmless and short-lived, a Chicago dermatologist says.
"A single hive tends to last for a few minutes to a few hours. Most hives clear within 24 hours," Dr. Danilo Del Campo said in an American Academy of Dermatology news release.
Several factors, including sunlight, stress and an allergic reaction to food or medicine, can cause hives, also known as urticaria.
While anyone can get hives, Black women, people who have eczema, and smokers are at increased risk.
If you have darker skin, hives are often the same color or slightly darker or lighter. If you have lighter skin, hives will appear red or pink.
Del Campo offered these tips to get relief from hives:
"If your hives don't clear after following these tips, talk to a board-certified dermatologist," Del Campo said.
Get immediate medical care or go to the nearest emergency room if you have hives along with any of the following: problems swallowing, feeling light-headed or faint, have swelling in your mouth or throat, a racing heart or shortness of breath or trouble breathing.
