What is the description of cold urticaria medical term?

Cold urticaria, also known as cold-induced urticaria, is a skin condition that causes itchy, red, raised bumps (hives) in response to cold temperatures. It is a type of physical urticaria, which is a group of skin conditions that are triggered by physical factors, such as heat, cold, pressure, or sunlight.

Cold urticaria is most commonly caused by exposure to cold air or water, but it can also be triggered by handling cold objects or eating or drinking cold foods or beverages. Symptoms usually develop within a few minutes of exposure to cold and can last for several hours. In some cases, cold urticaria can also cause more severe symptoms, such as swelling, difficulty breathing, and anaphylaxis.

The diagnosis of cold urticaria is based on the patient's history of symptoms and a physical examination. In some cases, an ice cube test may be performed to confirm the diagnosis. This involves placing an ice cube on the patient's skin for a few minutes and then observing for the development of hives.

Treatment for cold urticaria typically involves avoiding triggers, such as cold temperatures. In some cases, medications, such as antihistamines or steroids, may be prescribed to help control symptoms.
