Headaches

I have had a horrible headache for about a week or two. It's like someone had smacked the right side of my forehead, and this morning the pain was unbearable until I went to Cub and got some scalloped potatoes and a chicken tender. The small meal turned the pain from excruciating to a dull throb, and now it barely hurts at all. I am glad but mystified, as unsure of the origins as I am of its cessation. It was so bad this morning I could barely sing, then food made it go away. As I said, it was a mystery, and it was starting to scare the hell out of me.
