Pain becomes conscious to us via the brain. Pain is local to the cut. Rather signals from nerves near the cut, are sent to the brain. These signals are then interpreted by the brain, as pain at a specific location. Consciousness of pain comes down to the mind, and how the mind interpret these particular nerve signals. Some people like pain and will interpret this with a pleasure reaction; firmware cross.
I remember going to a mind control course when I was young; Silva Mind Control. One of the skills they taught was controlling pain. I may have been hypnotized, but after the course, all I had to say was, gone, gone, gone and pain would go away in minutes. I could shut off pain, because these command lines told the brain to shut off the awareness. Today anticipation of pain is worse for me that the actual pain; needles. The actual pain seems less than the expectation. Luckily for me, these are not integrated within my mind to amplify the real pain signal.
Satan would be symbolic of a renegade aspect of the personality firmware, that is amplifying the brains reactions to the incoming pain signals. This is causing a larger chain reaction in the brain than should be. This is where something analogous to anticipation and real time pain signals integrate. Pain control may involve command lines like prayer. If the anticipation pain is shut off, the real pain is more manageable.
