FurballsMom is right, i know that it is better to drink room temp water because if you drink cold water say from the refrigerator, then it hits the gut too hard and can feel to heavy on your stomach, it also may feel likes its going through you too fast that way too.
good luck

I don't know what is wrong, but in the past I've had some similar discomfort when drinking plain water. I was told to drink room temperature water and to drink it very slowly, like sips, and wait a while before drinking any more water.
I'm sure someone else will come along who may be able to give you more ideas as to what may be wrong. I only know about the water temperature and drinking slowly by sipping the water.
