What should you know about pruritus ani worse at night?

The skin around the anus can become itchy when moisture, stool residue, sweating, fragranced products, or vigorous cleaning irritates its protective barrier. Scratching then creates more inflammation and tiny breaks in the skin, which can make the itch feel stronger when you are resting or trying to sleep. Dry or inflamed skin conditions such as [Asteatotic Eczema](/conditions/asteatotic-eczema/), [Atopic Dermatitis](/conditions/atopic-dermatitis/), and [Contact Dermatitis](/conditions/contact-dermatitis/) may present with itching in this area.

A clinician may also consider [Skin Yeast Infection](/conditions/cutaneous-candidiasis/), [Lichen Planus](/conditions/lichen-planus/), [Psoriasis](/conditions/psoriasis/), or an infestation such as [Scabies](/conditions/scabies/). The timing alone cannot identify the cause.

Rinse gently with lukewarm water, pat dry rather than rubbing, and avoid scented wipes, perfumes, harsh soaps, and repeated scrubbing. Wear breathable underwear, change after sweating, keep nails short, and try not to scratch. A thin protective barrier recommended by a clinician may help when moisture is contributing.

Do not repeatedly apply steroid, antifungal, anaesthetic, or other medicated creams without advice, because the wrong product can mask the appearance or further irritate the area. Arrange an assessment if the itch persists, disturbs sleep, spreads, or returns after self-care. [Hives](/conditions/urticaria/) can also cause itching, although the rash pattern and examination guide the diagnosis.

Arrange prompt medical review for bleeding, severe pain, a lump, open sores, pus, fever, marked swelling, a new rash, or discharge. Seek urgent care for rapidly spreading redness, severe allergic symptoms, or inability to pass stool or urine. A clinician can inspect the skin and choose testing or treatment when needed.

Ask what the skin looks like on examination, whether infection or an inflammatory condition is suspected, which cleanser and barrier are suitable, and how long to use any prescribed medicine. Mention travel, household itching, new products, bowel changes, sweating, and nighttime symptoms.
