Why do we get an itch? even if its not a medical related illness.....where does an itch come from?

Do basic skin care: Dry skin is the most common cause of chronic itching and people often associate itching with being dirty etc...As a result, they clean the skin too much--soaps, scrubbing, frequent hot showers/baths, all of which can make the itching worse. So, minimize hot showers, harsh-soap, and increase use of skin moisturizer 2-3x/day, especially right after showering. If not better, consult doc.. Good luck.
