Mine have been ringing off/on for a few days, and I also woke up with a splitting headache today, which lasted most of the day until I finally gave in and took an advil. I rarely have a headache, so I always take notice when I do.

Last time I had a headache like that, the 7.8 in Fiji struck (in Sept). I don't typically jump to making associations of that nature in my case because I can't say I've truly noticed any particular pattern. But I had a dizzy spell out of nowhere in that same 24 hour period, which I've never had and there was no reason for it. The combination of weird symptoms makes me wonder if it was indeed related though, especially with a quake of that size.
