Urticaria, commonly known as wheals or hives, is referred to as 'Yinzhen' in Chinese medicine. It results from temporary increased vascular permeability in the skin and mucous membranes that causes localized edema. Chronic urticaria is defined as recurrent skin lesions for more than six weeks, with outbreaks occurring at least twice a week. Symptoms of chronic urticaria are generally mild overall, with varying frequency and intensity of hives that can persist for months or even years. Most cases of chronic urticaria are associated with infections or systemic diseases. Most patients with chronic urticaria are heat-sensitive; their itching worsens with heat exposure and the wheals are bright red. However, there is a special type of chronic urticaria known as cold-induced urticaria. This type is rare and has familial ties, usually associated with autosomal dominant inheritance. Another more common type is acquired cold-induced urticaria, which manifests after exposure to cold air, water, or objects. The exposed or contacted areas develop wheals. In severe cases, symptoms can include localized numbness, chest tightness, palpitations, abdominal pain, diarrhea, and even fainting or shock. Consuming cold beverages might also cause swelling in the mouth or throat.
