Also known as Pruritis Ani, Anal Itching, Rectal Itch, Itching Rectal, and Perianal Pruritus
Pruritus ani (also known as anusitis) is the irritation of the skin at the exit of the rectum, known as the anus, causing the desire to scratch. The intensity of anal itching increases from moisture, pressure, and rubbing caused by clothing and sitting. At worst, anal itching causes intolerable discomfort that often is accompanied by burning and soreness. It is estimated that up to 5% of the population of the United States experiences this type of discomfort daily.Source: Wikipedia
