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.

Hives: Acute urticaria, or hives, often occur and disappear before we figure out cause. Benadryl (diphenhydramine) or Zyrtec (longer acting and less sedating) are otc antihistamines that may help for acute hives. If they recur after swimming, then chronic cold-induced urticaria is a consideration and can be diagnosed in the office with a simple test. This can be serious as swimming can cause shock/death in such cases
