What's The Collective Noun For Headaches?

      A thunderation, perhaps.  A perturbation?  Maybe.

      A succession of headaches, migraines with visual effects, has made my life increasingly unpleasant.  I spent most of yesterday in bed and this morning, I felt less rested than the day before.

      No telling what's caused it but it's frustrating and embarrassing to be laid so low by something with no visible symptoms.  At least a broken leg shows up in an x-ray image!  It would be nice to lay the blame for them on our increasingly self-lobotomized political discourse, but that's far too easy.  I'd even blame it on my frustration with some aspects of my job, but it's been worse and most of what's wrong there now is wrong everywhere. 

      I get headaches.  I've done so for years and (after a fruitless multi-year hunt for a cause and cure) mostly I gripe about it and take an OTC pain reliever.  Sometimes that's not enough.
