Open Question: My skin is falling off?

I have no pain, my wounds and swelling, but not my skin is the continuous decline of. My fingers on the skin and peeling skin on my heel does not feel the same, even now my forehead skin. It is not to stimulate the skin or under a new layer, does not touch sensitive. I wonder if this may cause it to begin my hand, and then my feet, and now my head is just worried about the bad things immediately.
