Question: What are you suffering from if you’re hit by an attack of sphenopalatine ganglioneuralgia?
Answer: You’ve got brain freeze. The abrupt cooling of the roof of your mouth triggers a brain freeze, also called an ice cream headache (or sphenopalatine ganglioneuralgia, if you’re a scientist). The onslaught of cold causes nearby blood vessels to constrict and then expand, and that fluctuation is interpreted by the brain as a mind-numbing pain.
