Urticaria pronounced ur-tuh-keh-ree-uh is another term for hives (wheals). The term comes from Latin origin with “urere,” meaning to burn and “urtica,” meaning nettle. More modern interpretation comes from the European “stinging nettle” Urtica Dioica. Three million Americans are affected with urticaria each year.
Classified as a rash, urticaria presents as itchy, raised, red, or skin-colored welts on the surface of the skin. A form of urticaria-angioedema differs in several ways. Edema is present under the surface of the skin and is marked by deep swelling, usually occurring on the face, throat, feet, and hands. Generally, the swelling dissipates in less than a day.
urticaria can present as tiny bumps not much larger than a pinhead. They can be several inches wide. They often appear pink or skin-colored, but when pressed in the center, the area can turn white.
