This is the pain pacemaker. I've got a battery under my skin. From that battery are two electrodes that go into the spine where they cut bone away to accommodate it. Now I put on the power here. If I have the pain the stimulator starts. It's tingling like when your foot falls asleep you know?
I suspect the psychological pressure associated with that crisis caused the first mental blackout I had ever suffered. It contributed to a deterioration in my health that later required the insertion of a heart pacemaker.
