Specializes in Allergy and Immunology

Cold Urticaria/Hives: Sound like cold-induced urticaria (hives) if symptoms appear after exposure to cold ocean water. Physical urticarias are disorders in which wheals are induced by environmental stimuli like heat or cold. Hives are limited to cold-exposed skin and develop within minutes of exposure. Ice-cube challenge can be done by Allergist to confirm. Avoidance of cold is best, also nonsedating antihistamines.
