I believe that the 'brain freeze' could be caused by referred pain
due to stimulation of pain receptors in the palette. These receptors may
propogate action potentials along non-myelinated fibres, accounting for
the latency before the pain is felt.
Nociceptors (pain receptors) do not show a short-term adaptive
response, and this could explain why the pain does not seem to dissapate
until the palette is warmed again (by the toungue etc.). Also, the pain I
feel when experiencing a brain freeze reminds me of that experienced when
eating horseradish or wasabe. Both of which contain isothiocynates, which
activate the receptor responsible for painful cold sensation.
The pain felt in the throat and stomach reported by some people could
simply be a result of quickly swallowing the cold substance so it is still
cold when reaching the throat and passing through the thorax.
This is merely speculation and I apologise if I have stated anything
incorrectly.

Could be referred pain?
