Hi Seems like your husband has developed aquagenic urticaria, also known as water allergy , water urticaria and aquagenous urticaria which is a rarely diagnosed form of physical urticaria. Aquagenic urticaria usually causes the skin to itch and burn after being exposed to water of any kind.The skin may develop hives. Showers may result in severely dry eyes and soreness. Higher water temperatures tend to expedite the formation of hives. Contact with any form of water can cause symptoms to appear. One s own or someone else’s sweat can cause a reaction, so most affected people try to stay cool in summer to avoid sweating as much as possible. Tears on one s face from crying can also cause pain. here is no known treatment for aquagenic urticaria. Dermatologists recommend avoiding contact with water as much as possible by taking short showers, staying cool, and avoiding rain to ease symptoms. Antihistamines and other types of medications may be prescribed to help reduce the intensity of the reaction. In some very mild cases a medicine such as benadryl can be taken to relieve the hives. Hope it helps Dr Geetika Paul
