Anal itch is an irritating sensation around the anus that is relieved temporarily by scratching or rubbing. The problem is often worse at night and may interfere with sleep. In most cases, the skin in the area is red.
If anal itch becomes a chronic (long-term) problem, the skin around the anus may become raw and tender from repeated scratching, or it may thicken and become leathery. Repeated scratching also can cause breaks in the anal skin that can lead to painful local infections.
