sphenopalatine ganglioneuralgia is also known as "brain freeze" or "ice-cream headache."
From Wikipedia:
"An ice-cream headache, also known as brain freeze, cold-rush, cold-stimulus headache,[1] or its given scientific namesphenopalatine ganglioneuralgia (meaning "nerve pain of the sphenopalatine ganglion"-and is also considered a misnomer since the pain nerves have nothing to do with the sphenopalatine/pterygopalatine ganglion, but travel along the trigeminal nerves described below), is a form of brief cranial pain or headache commonly associated with consumption (particularly quick consumption) of cold beverages or foods such as ice cream and ice pops. It is caused by having something cold touch the roof of the mouth (palate), and is believed to result from a nerve response causing rapid constriction and swelling of blood vessels[2] or a "referring" of pain from the roof of the mouth to the head.[3][4] The rate of intake for cold foods has been studied as a contributing factor.[5][6]"
While it may be a little cold to think about ice cream, it does remind us all of the nice weather that will eventually come.
