Answers:
All itches result when the local stimuli are irritating the fibrous nerve endings on the upper layer of the skin. The brain interprets there stimuli as itches. Scratching can either remove the stimuli or cause pain in the area of the itch, which neutralizes the itching sensation in the spinal cord.
