Acute urticaria

What is acute urticaria?

Urticaria (sometimes called hives) is an itchy rash caused by tiny amounts of fluid that leak from blood vessels just under the skin surface. Urticaria is classed as:

• Acute urticaria - if it develops suddenly and lasts less than six weeks. Most cases last 24-48 hours. About 1 in 6 people will have at least one bout of urticaria in their life. It can affect anyone at any age. Some people have recurring bouts of acute urticaria.
• Chronic urticaria - if it persists longer than six weeks. (Chronic means persistent or ongoing.) This is uncommon.

This rest of this leaflet deals only with acute urticaria. There is a separate leaflet for information about chronic urticaria. http://www.patient.co.uk/showdoc/23068849/

Hope this will end soon =(
