Is there a simple answer?
|Quoting Flyingbabydoc (Reply 1):|
Yes. You stimulate tactile receptors in the skin which in turn override the "itching" sensation neurons in the spinal cord, promoting relief of the "bad" sensation and informing the body that the possible injury (perceived as an itch) has been removed.
That is the same principle applied when you decrease the pain from an injury by rubbing it
|Quoting Matt72033 (Reply 2):
how come when you scratch a mosquito bite or a rash it itches even more?
