According to experts, the skin lesions of cold urticaria are limited to the site of cold stimulation, and sometimes it may spread all over the body or involve oral mucosa. In severe cases, it will be manifested as headache, diarrhea and rapid heartbeat. After suffering from this disease, itching occurs first, then wheals of different sizes occur, and the rash may break out quickly or disappear quickly.
