just the soft spot in the back top of your mouth freezes.. its like when your leg or foot wakes up from a sleep and its all tingly.. same effect.. the nerves as they warm back up.. give a painful tingly feeling..
they gave you a more scientific explaination above
Ice cream headache is the direct result of the rapid cooling and rewarming of the capillaries in the sinuses. A similar but painless blood vessel response causes the face to appear "flushed" after being outside on a cold day. In both instances, the cold temperature causes the capillaries in the sinuses to constrict and then experience extreme rebound dilation as they warm up again.[9]
In the palate, this dilation is sensed by nearby pain receptors, which then send signals back to the brain via the trigeminal nerve, one of the major nerves of the facial area. This nerve also senses facial pain, so as the nerval signals are conducted the brain interprets the pain as coming from the forehead—the same "referred pain" phenomenon seen in heart attacks. Brain-freeze pain may last from a few seconds to a few minutes. Research suggests that the same vascular mechanism and nerve implicated in "brain freeze" cause the aura (sensory disturbance) and pulsatile (throbbing pain) phases of migraines.[10]

No. Oxygen deprivation would lead to you passing out. Just above the roof of our mouth (inside our head) is a bundle of nerves called the sphenopalantine ganglion. When a person eats cold food, the extreme difference in temperature between body temperature and the temperature of the food is detected by these nerves. The nerves sense that this part of the head is getting cold and send a signal to the brain telling it that one part of the head is cold and to anticipate that the rest of the head is going to get cold. Our brains will not live in a cold environment and therefore, as a protective mechanism, our brain tells the body to increase blood flow to the blood vessels in our brain to keep it warm. The increase in pressure in the blood vessels causes a headache.
i like that pain it makes me happy that im alive going now to eat some ice pain
