I like this explanation (and the discussion as a whole).
I'm a biochemist, so forgive the lack of anatomical knowlege, but the recent postings do
support a fact I have noticed - that migraine pain and ice-cream headache are VERY similar
in location and type (tho' not in their extremity and location). I understand that migraine
is caused by alterations in bloodflow, so a similar change in bloodflow causing ice-cream
headache would be acceptable as an explanation to me.
BTW - if you're ever in Oxford UK (on a conference etc) check out George and Davis ice
cream, Little Clarendon St, it's the best in the world (I don't have any links at all with
them, I just love good ice cream!)
