Definately avoid itching and go see your dermatologist, or a dermatologist. Usually if you tell them you have scabies they can get you in for a rush appointment. The way scabies spreads throughout your body is becuase you itch wehre they are at, and then they are under your fingernails. Then if you itch, say, your stomach, they can be planted there and burrow in to your stomach. So the faster you get a treatment, any treatment, the less of an infestation you will have.
