A hit-and-run vertigo day yesterday. Got up feeling fine, but by the time I got to the office had a blinding sinus headache. Within about half an hour the tinnitus got loud and weird--like someone had shoved a cicada in my ear. I went home and took sudafed, finished my paper, and waited it out. The tiltiness only lasted a couple of hours and by bedtime I was fine, if a little dehydrated and tired.

I'm guessing it's entirely sinus related (maybe a little stress), since I've been keeping the sodium pretty low since my last attack in mid-August, and it's not that TOTM. Odd.
