For as long as I can remember, I have had this itch.

On my back, just below my right shoulder blade. Most days it is out of my reach... some days I am flexible enough to reach it.

Yet it never completely goes away. Scratch it. Lotion it. Hot water. Cold water. Nothing seems to make it go away.

Nothing is there. No welt. No mark. No visible evidence. No explanation.

Just an itch.
