Hi Jeremy, The pain definition by IASP might help, " An unpleasant sensory and emotional experience associated with actual or potential tissue damage, or described in terms of such damage". From what I understand, so even bumping your head into a door frame or acute pain has an emotional component. As they say " no brain, no pain". So I am not sure if we can tease out the emotional from the sensory/physiological. Check Lorimer Moseley when you get a chance.
