 I've never had any kind of sinus problems, and I've also never felt an earthquake before. But four days before that jolt, my head began to stuff up, and I got a tremendous headache that aspirin couldn't touch. I was hyperactive. I couldn't even stay seated at luncheon with some teacher friends two days before the quake. The day before the quake, I felt compelled to clean my house from top to bottom, and I'm normally quite content to leave books on the dust balls and the dishes in the sink and go to my studio and paint.
