Do you have a left-sided migraine ?

Since Thursday, I've had one of those annoying migraines that's just bad enough that meds are needed every few hours, and the symptoms are a little over the top of the pain in my left eye, jaw, and behind the ear. A little twinge on the left side of my head every once in a while seems to be correlated to the Alaska activity, in the 4.magnitude range.

Alaskan activity has been known to precede stronger activity in Southern California. Southern Californians should be checking your earthquake packs.
Make sure you have extra migraine meds on hand, and that the exp.date is still good.

Other areas on the planet are starting to shake and quake, and do contribute to the twinges you are feeling.
If these quakes get any stronger, you may experience a little migraine vertigo.

This should effect the next 48 hours. If the quakes rotate as usual, expect a day in between, before your headache and symptoms go to the right side.
