Lichen planus on the feet: treatment and care

Foot lichen planus may appear as itchy bumps, darker or purplish patches, thickened skin or irritation around the ankles and tops of the feet. Pressure and shoe friction can make symptoms harder to tolerate. The appearance can overlap with eczema, fungal infection or other rashes, so a clinician may inspect the skin closely and sometimes test a sample. Read about [Lichen Planus](/conditions/lichen-planus/), [Itchy Skin](/symptoms/itchy-skin/) and [Skin Bumps](/symptoms/skin-bumps/).

A prescribed [Topical Corticosteroid](/treatments/medical-dermatology/topical-corticosteroids/) may be applied to active areas, with the strength and duration chosen for the location and thickness of the skin. Do not apply it between toes or over broken skin unless instructed. Wear well-fitting shoes, keep feet clean and dry, and use a plain moisturiser on dry surrounding skin. If the eruption is widespread or difficult to control, a dermatologist may discuss [Oral Corticosteroid Treatment](/treatments/medical-dermatology/oral-corticosteroid-therapy/) or another option.

Book an assessment if foot bumps persist, become painful, crack, bleed or interfere with walking. Seek prompt care for warmth, pus, rapidly increasing redness, fever, or swelling of the foot. Diabetes, poor circulation or reduced sensation makes a new foot wound more urgent to have checked.

Ask whether the rash needs testing, where to apply treatment, whether cracked areas need separate care, and how to protect your feet from shoe friction. Ask what improvement should look like and when a review is needed if thickened or discoloured skin remains.
