Itching: Is It On The Skin Or Is It In The Mind?

I have heard about people who have unfortunately had to have their arm amputated.





And still have an itchy feeling on this arm. Which does not exist-hence the condition phantom arm.





So is an itch a problem with the skin? Or is it an imaginary itch that the mind is determining.





Thank you for any answers

Itching: Is It On The Skin Or Is It In The Mind?
well.. it's both, If something tickles the sensory nerves on the surface of the skin, the nerve sends an impulse of this stimulation to the brain, then you conciously move your hand to scratch it.





With the amputee's arm itching, its because the nerve endings are stimulated in a specific way to send impulses to your mind, the mind (which is on autopilot because its recieved the same messages a million in its life) then interprets these messages as further down the line and tries to react accordingly.





over time the mind re-configures its nervous impulses to match what it feels to what is happening but there is no immediate cure for it, just another downside to having an amutation.

Reply:both when we get a rash we itch but phantom pain is real because of the nerve endings
