Why am I itching all over my body, and what can I do about it?

ITCHING ALL OVER. How long have you been itching all over? Do you take any medications? Is the itch all below the waist, or does it also itch on your face and scalp. Anybody else in your family or your friends itch? Do you have a cat or dog? Have you changed your soap or laundry detergent? If it persists, see a doctor, preferably a dermatologist.
