Answer 1

because they itch???????????????????????????????

Answer 2

"Nerves send us the nasty, prickly feelings. While some nerve fibers focus on feeling pain and touch, we have others dedicated to the itch sensation.

Histamine, a protein released during an allergic reaction, commands some of our itch nerves to transmit information to the spinal cord where it is processed and zipped off to the brain. The sites activated in the brain when we itch are very similar to those switched on when we're in pain

Scratching might turn on nerves that stimulate pleasure systems in the brain."
