Hives, also known as urticaria, are the pale red bumps that can be itchy and usually appear suddenly. Hives are very common and occur in 20% of population at some point of their lives. Most commonly, hives occur as an adverse reaction to certain allergens. They appear due to release of a chemical called histamine into the skin. Histamine is released from skin cells that lie along blood vessels and it causes the blood vessels to contract allowing the plasma to leak out. Apart from allergic reaction, hives may be caused by medications, insect stings, sun exposure and chemicals in the food, while the reason is sometimes unknown. Common allergens that cause hives are fish, dairy products, nuts, food additives, preservatives, flavorings, penicillin and Aspirin.
