The Phantom Itch

Aside from the fact my feet still bother me, I have developed what appears to be a phantom itch. I will have an itch in and around my chest area and no mater how quickly I get to it or how hard I scratch, it doesn't do anything to abate the itch. It even seems like the itchy spot moves. I figure it is just a bad combo of internal healing and dead nerve endings, but man it is driving me nuts.
