Itchy skin can affect small areas, such as the scalp, an arm or a leg. Or it can cover the whole body. Itchy skin can occur without any other noticeable changes on the skin. Or it may come with:  Inflamed skin Scratch marks Bumps, spots or blisters Dry, cracked skin Leathery or scaly patches  Sometimes itchiness lasts a long time and can be intense. As you rub or scratch the area, it gets itchier. And the more it itches, the more you scratch. Breaking this itch-scratch cycle can be difficult.
