Severe headache (8)

Ross

I believe the answer is:

migraine

'severe headache' is the definition.
(I've seen this before)

This is all the clue.

(Other definitions for migraine that I've seen before include "misery in capital area" , "Recurrent throbbing headache" , "Severe recurrent headache" , "Severe headache often accompanied by nausea" , "Long nerve fibre" .)

I've seen this clue in the Sydney Morning Herald, The Independent and The Guardian.
