The pain signals do not originate in the brain. The head does have other
components, you know, all of which can signal pain. Besides, people's
reports of where pain signals originate can be quite unreliable - it's
one of the reasons people have to be told that the pain associated with
the onset of a heart attack usually does not seem to come from the heart.

As for people reporting that they experience "stimulation in the brain
and spinal cord" - I wouldn't trust the reports of anyone under the
influence of drugs without corroborating evidence such fMRIs or PET
scans, or controls such as anesthetising certain nerve pathways, etc.

That good enough? If not, I suggest you take it up with some neurologists.
