Cold Urticaria (essentially meaning "cold hives") is an allergy where hives (urticaria) or large red welts form on the skin after exposure to a cold stimulus. The welts are usually itchy and often the hands and feet will become itchy and swollen as well. Hives vary in size from about the size of a pencil eraser (7 mm diam.) to as big as a fifty pence piece (27 mm diam.) or larger. The disease is classified as chronic when hives appear for longer than 6 weeks; they can last for life, though their course is often unpredictable. This disorder, or perhaps two disorders with the same clinical manifestations, can be inherited (familial cold urticaria) or acquired (primary acquired cold urticaria). The acquired form is most likely to occur between ages 18–25.

Famous quotes containing the word cold:
“I am speaking now of the highest duty we owe our friends, the noblest, the most sacredthat of keeping their own nobleness, goodness, pure and incorrupt.... If we let our friend become cold and selfish and exacting without a remonstrance, we are no true lover, no true friend.”
—Harriet Beecher Stowe (18111896)
