Gerry, is't it time you did some reading and study up on this interesting subject?, while sometimes close to the mark here and there, your constructs and self generated conclusions are full of the kind of holes that even one recent book on pain could clear up for you.
No disrespect intended honestly.
Try "Explain pain " by Butler and Mosely.
It's the kind of decent up to date detail you would find fascinating.
Stay curious .
Cheers
