Pruritis ani is a dermatological condition characterized by itching in the anal area. 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. Pruritis ani is about 4 times more likely to occur in men than in women.
