Hives are red patches or bumps that appear swollen and feel itchy. They can also burn or sting. Hives can show up anywhere on your body, including inside your throat, on your tongue, on your face, or on your torso. They can show up virtually anywhere. They can range in size from a centimeter to a foot or more. They can even mesh together and form plaques.
They can last anywhere from a couple of hours to a couple of weeks, but some may go on for months or even years. Hives have a number of causes, from allergic reactions, to food chemicals, to sunlight, to insect stings. Certain foods can cause hives. Hives can look really scary if you’ve never seen them before. They can stand out and look really strange. Some people might assume hives are something very serious, but they’re usually not serious and go away on their own.
