To help CPR practitioners to remember the order of the procedural steps, the acronym ABC was taught to stand for Airway, Breathing, Circulation. In 2010, the order of the steps was changed to Circulation, Airway, Breathing, so the acronym is now CAB.
The Itching is usually due to a disturbance in the skin of the external auditory canal. Ear canal skin is very sensitive. The slightest accumulation of debris, even a dead hair, may be felt as an itching sensation. Often, dryness in the ear is what causes inner ear itching.
My roommate and I were just discussing how there's nothing that we find more unattractive (besides dirt and body odor/bad breath) than ear wax in someone's ear. I can't believe that your ear itches because of a lack of wax and that Q-tips cause a temporary fix to the itch but in the long run remove the wax that prevents the itch in the first place... Ironic does not even begin to describe this!
