Hives occur when inflammation of the skin is triggered by the immune system due to an allergen. The immune system releases histamine, which causes swelling. The swelling in the deep layers of the skin is called angioedema. This causes small blood vessels to leak, which leads to swelling in the skin.
Urticaria can be classified as acute and chronic. Acute urticaria often occurs at times after eating certain foods or having some contact with a particular trigger. Some examples of triggers include: non-allergic causes such as food, medications, heat or exercise, insect bites or even an infection. A chronic urticaria is rarely caused by specific triggers, so allergy tests are not always helpful. A chronic urticaria can last for many months or even years. Hives are not contagious but can be uncomfortable and sometimes painful for most people.
