I too have had the same problems with water. The red splotchy marks, itchyness, hives, the pain! It doesn't matter if it is city, well, lake, or rain water. I went to the doctor today, I finally got up the courage to tell her and she laughed, not at me, but at the fact she has never heard of such a thing. No-one at the office had. I have been living with this for a few years, and it seems to be getting worse. I have tried allergy medication, before I shower, but it only eases the itching.
Now my question...
Has anyone experienced any problems when drinking water? It gives me a burning sensation, then my stomach aches and burns for hours after. I have tried all types of different bottled waters. Nothing else I drink bothers me, just water!
