Sole itching at night: what it may mean and what to do

Dry, tight, flaky skin may point towards a damaged skin barrier, especially after hot showers, frequent washing, or dry indoor air. Redness, scaling, cracking, or burning can occur with eczema or contact irritation from footwear, socks, detergents, or products applied to the feet.

A yeast infection may cause itch with peeling or moist-looking skin, often between the toes, although the sole can also be involved. Thickened, sharply bordered, or repeatedly scaly areas can occur with psoriasis. Itch that is intense at night and affects household contacts raises the possibility of scabies; small bumps or burrows may be present elsewhere too. Hives tend to cause raised, itchy areas that come and go.

Wash with lukewarm water and a gentle, fragrance-free cleanser, then pat the feet dry rather than rubbing. Apply a plain moisturising cream or ointment while the skin is still slightly damp, and change out of sweaty socks. Keep footwear dry and avoid scratching, new foot products, and fragranced laundry products until the cause is clearer.

Do not share towels, socks, or shoes if an infection or scabies is possible. A pharmacist or clinician can help choose treatment when there is scaling, a spreading rash, broken skin, or persistent night-time itch; the right treatment depends on the cause.

Arrange a clinical assessment if the itching persists, keeps returning, interrupts sleep, or comes with a rash, cracks, swelling, pain, discharge, or signs of infection. Seek prompt care for rapidly worsening redness, warmth, marked swelling, fever, or difficulty walking. Get urgent help if itching occurs with facial or throat swelling, wheezing, or trouble breathing.

Ask which findings best distinguish eczema, contact irritation, fungal infection, psoriasis, and scabies; whether any medicine or product could be contributing; and how to protect the skin while treatment is assessed. Mention when the itching began, whether both soles are affected, and whether anyone else at home is itchy.
