Part of the mis-wiring (for me anyways) is that the sympathetic system is jacked up -- I often don't have an appropriate response to impending or near-recent injury. You do still feel it, just different than I remember (although my memory of normal is pretty faded) One thing that is notable is that other (normally non-painful stimuli such as a glancing touch or intermittent contact - like a shower) are astonishingly painful.
