Định Nghĩa và Ý Nghĩa của "hives"

What are "hives"?

Hives, also known as urticaria, are raised, red, and itchy bumps that appear on the skin. They can vary in size and shape and often appear suddenly as a result of an allergic reaction to certain foods, medications, insect stings, or environmental triggers like heat or cold. Hives can also be triggered by stress or infections. While they usually disappear on their own within a few hours or days, they can be uncomfortable and bothersome. Treatment may involve over-the-counter antihistamines or prescription medications to relieve itching and reduce inflammation, along with identifying and avoiding triggers to prevent future outbreaks.
