Why does sometimes when you cut into a particular spot, another spot feel approaching its individual scratched??

...its like this constituent itches at the exact same time.. and then you cut into it and both of the spots becomes artificial by the scratch when you're singular scratching one spot..Why does sometimes when you cut into a particular spot, another spot feel approaching its individual scratched??
It is because it is within your head..you surface relief from scratch one spot and your subconsiously think of the nouns and how it would feel on the other spot :)..kinda tricks your brain into thinking it already have been relieved .
i don't know but i know exactly what your wise saying.
you scratched at the wrong butt.
i think scratch one spot makes your brain distracted from unfolding the other spot to feel similar to it needs to be scratched
bring the nerves communicate with respectively other and the signal is transmitted at a small distance...
