If you were ever diagnosed with this, you’d probably be sounding out the spelling as you typed it up on WebMD before your doctor even finished their sentence, right?
Actually, your doctor would probably be laughing as they gave you this diagnosis because the term simply refers to a cold-stimulus headache, also know as a brain freeze.
The etymology is a little more complex than the actual condition. Sphen refers to the sphenoid bone, palatine means “pertaining to the palate,” gangli refers to the concentration of neural bodies known as the ganglion, neur means “nerve,” and the suffix algia means “pain.” That’s a mouthful.
