Some say it is more a hypersensitivity to the ions found in non-distilled water.Whether it is so or not can be a trial and error.Try bathing once with mineral water instead of tap water.Always do not lock your self in should you develop a severe type anytime.From your history seems a mild type only.Does this happen with cold or hot water?or both?

Hello,
Water urticaria, or aquagenic urticaria, is a rare condition in which hives develop within 1 to 15 minutes after contact with water. The hives last for 10 to 120 minutes and do not seem to be caused by histamine release like the other physical hives. Most investigators believe that this condition is actually exquisite skin sensitivity to additives in the water such as chlorine but distilled water can also cause this reaction.

Treatment of water urticaria includes epinephrine, antihistamines, or cortisone-like drugs. Itching can be controlled with cold packs or commercial topical agents that contain menthol, camphor, eucalyptus oil, aloe, antihistamines, or cortisone preparations

Hope it helps. Take care and pls do keep me posted on how you are doing or if you have any additional queries.Kind regards.
