What is Cold Urticaria?
Cold urticaria is a rare allergic reaction to cold temperatures that can cause hives, itching, and swelling on the skin after exposure to cold air, water, or objects. Symptoms of cold urticaria can vary in severity, ranging from mild discomfort to more serious reactions such as difficulty breathing or a drop in blood pressure. Managing cold urticaria typically involves avoiding exposure to cold environments, wearing protective clothing, and taking antihistamines to alleviate symptoms.
