Hoo Boy

I was standing in the kitchen, literally just standing, when it was like something in the small of my back decided to say, "Hello." 

Just off center on the right side, a squeeze like someone had their hand somehow inside that complexity of muscle, and had just found a set or strand of muscles to grip and pull. But gently.

I continued to stand, with what I imagine was a rather foolish look on my face, as the pain quickly increased, the grip of that invisible hand tightening, and then I said, "Hoo boy."
