Anal itching is a common condition. The itch, situated in or around your anus, is often intense and may be accompanied by a strong urge to scratch. You may find anal itching to be embarrassing and uncomfortable.

The itching may become worse at night or after a bowel movement. Scratching the area results in further irritation and makes the itching worse instead of relieving it. Scratching with the fingernails may result in skin damage or an infection. If the itch-scratch cycle persists, it can lead to extreme discomfort, soreness, and burning. Pruritus ani is about 4 times more likely to occur in men than in women.
