Urticaria is an eruption smooth, raised, pink or red bumps of various sizes called wheals. Hives appear suddenly. Papules seem a bit 'like mosquito bites. They may cover all or part of the body and are usually very itchy.
Hives usually appear first on the areas covered with skin, such as the trunk and upper arms and legs.
Papules in batches. Each wheal may last from minutes to six hours. Papules disappear, new forms. A case of hives last more than a few days.
Hives are usually fragmented at first, but the patches may work together until the hives cover most of the body.
The patches can be small or large. They are usually irregular in shape. Often the spots are clearing the redness of the red center of the ring or flare at the edges.
Itching is often very intense.
Hives are characterized by bleaching, which means that the redness disappears and the area becomes pale when pressure is applied.
Dermographism may be present. Dermographism refers to the appearance of redness, and rashes that appear after light scraping of the skin.
Angioedema is associated with hives, but they have a different look. Angioedema describes a marked swelling, usually around the eyes and mouth. It can also spread to the throat, tongue, hands, feet and / or genitals.
The skin may appear normal, without any hives or other rashes.
The closed eyes may appear swollen.
The inflammation usually does not itch, but can be painful or burning.
The bumps may be symmetrical (same on both sides of the body).
As hives, swelling of angioedema may disappear by itself.
Other, more serious allergic reactions may occur with urticaria or angioedema. The reaction may start urticaria or angioedema, and then quickly switch to more severe symptoms. Most cases of severe reactions, which can be life-threatening emergency, is called an anaphylactic reaction. Symptoms of an anaphylactic reaction, the symptoms are the following:
