You can extrapolate from this to understand nerve propagation in other areas of the body. In my understanding of CIDP, the inflammation usually starts at a proximal nerve/muscle junction, then goes distal and then postal. From this graphic one can see how specific muscles are influenced, with surrounding muscles effected less. Pain is purely sensory and works in conjunction with the reflex arc to motivate the motor neurons to tell the sensory neurons, brain and mouth to say, “ouch!”.
