I believe you are working on the wrong model for understanding pain.
Consider the pain caused by rapping tubes of cold water and warm water
around a container and the subject who is holding the container reports
intense pain.

It should be obvious that no pains should be perceived.

I would suggest that pain is discrepant information on two or more channels
of information.

Pain management would suggest that the effort should be toward reducing the
power of the discrepant information.
Cutting nerves could increase the discrepant information.  Signal reduction
could be done through pain medicines, but ultimately the opponent process
will nullify the effect.  Ultimately pain management must involve learning
and accepting the current neurological organization as normal.
