What causes a brain freeze when drinking anything cold?
It's from your sinuses becoming too cold.
You have veins and arteries on the roof of your mouth that go to the brain, and when they become cold (your skin in the mouth is thin) it sends the coldness to the brain and causes pain, because blood is supposed to be hot. When you get brain freeze, a way to then make it stop is to rub the roof of your mouth with your thumb to create friction to warm the blood.
I believe you get brain freeze when the cold water/ice cream/whatever hits your soft palate at the back of your throat.
Drink some room temperature water and it will go away.
dilated arteries, check it out...

When cold stuff (like popsicles, ice cream or slushies) touches the roof of your mouth it can set off a nerve reaction (in the spheno-palantine ganglion, to be precise), that causes the blood vessels in your brain to swell. When the blood vessels swell, you get a headache. The headache usually lasts less than a minute.
