The back of my throat always feels weird when I drink water to, not sure if that's normal or not, it's sort of a scratchy sensation.

I have the same problem sort of. I've been told drinking hot/warm water is more beneficial to your health than drinking cold water.

When I drink hot/warm water it gives me a sore scratchy throat and makes me feel really nauseous.

But drinking cold water makes me absolutely fine, it's disappointing.
