My head is currently under assault by the ruler-of-all-headaches and his evilish minions. It feels like a large rock is ricocheting off the inside of my skull.

Shutting my eyes tightly = Ouch.

Sudden change in elevation = Ouch!

Jerking my head sharply in any direction = OWZARKDANGTHATHURTS!!!

The ruler-of-all-headaches had better cease his attack by Monday or I'm going to have a lousy birthday.
