What it is
Pruritus ani means itching of the skin around the anus (back passage). It is a common and often distressing problem, and the itching can be intense, particularly at night. It sets up a frustrating cycle: itching leads to scratching, which damages and irritates the delicate skin, causing more itching. There are many possible contributors, including irritation from moisture, sweat, or over-vigorous cleaning; skin conditions such as eczema or psoriasis; leakage of small amounts of stool or mucus (for example with piles or minor incontinence); threadworms (especially in children); certain foods; infections; and, occasionally, other conditions. In many cases no single cause is found, and it is put down to a combination of skin irritation and the itch-scratch cycle. Although uncomfortable and sometimes embarrassing, it is usually not serious, and it can be helped.
How it is treated
Management focuses on breaking the itch-scratch cycle, protecting the skin, and treating any identifiable cause. Good, gentle hygiene is central: cleaning the area gently (avoiding vigorous wiping or scrubbing, and perfumed or harsh products), keeping the area dry, and using soft materials. Avoiding known irritants and, sometimes, certain foods that seem to make it worse can help. Not scratching — however tempting — is important, and measures to reduce night-time scratching (such as keeping nails short) help. A doctor may check for and treat specific causes, such as threadworms, a skin condition, or piles, and may recommend a barrier or soothing cream, or a short course of a mild treatment for inflamed skin. Persistent or unusual cases, or any worrying features (such as bleeding, a lump, or skin changes), are assessed further. With consistent skin care and treating any cause, most people improve. The reassuring message is that itchy bottom is common, usually harmless, and manageable.
