Question

If you receive exactly the same painful stimulus to your hand or your back, which will feel more pain, and why

Answer 1

Your back

Step-by-step explanation:

Your spinal cord is one of the main hosts of sensory muscles and veins which are highly sensitive.

Also, a good rule of thumb is that your back is often more receptive to high or low-temperature precursors (such as scalding/freezing water) compared to the hand, so keep that in mind.

Hope that helps :)
