Are you sure it is the water itself, or some additive in the water - such as chlorine? I get hives on my forehead every time I take a shower, I get blotchy red skin from any exposure to swimming pools or bath/showers, and cannot drink tap water without getting sick to my stomach. I don't think H20 (the chemical formula for water) is the culprit, but rather stuff that is added to the water or not filtered out at the drinking water treatment facility. One of my allergies is Fluoride (added to tap water for the purpose of strengthening teeth), and that could very well be the culprit in my case. But there are a lot of other things in tap water that can cause problems too - recently, for example, research has discovered trace amounts of a wide variety of prescription medications in water. I can't help but wonder what the implications of that are for people with severe allergies to some prescriptions. The bottom line is that I think you might want to discuss the possibility of chlorine or other additives in water as the cause of your problem. Glad the Zyrtec helps, but would be good to know what is in the water that you are reacting to. Do you get these reactions if you travel to a different place? Might want to contact your local water treatment facility to find out what all is in the water, too.
