Why can lichen planus be painful?

Skin lesions may itch more than they hurt, while cracks, sores, or rubbed areas can sting or become tender. Oral lichen planus may burn during meals, particularly when food is spicy, acidic, salty, or rough. Genital involvement can cause soreness with touch or sex. Nail or scalp disease may hurt when nearby tissue is irritated. Pain intensity can change as inflammation settles, so its pattern and location are useful details for a clinician.

Keep affected skin clean, moisturised, and protected from friction. Wear loose clothing over tender areas and choose soft, mild foods when the mouth is sore. Avoid scratching, tobacco, and products that sting. A clinician may recommend a topical corticosteroid for suitable skin or lining, with instructions that match the site and strength. More widespread inflammation may lead to discussion of oral corticosteroid treatment. Read about [Topical Corticosteroids](/treatments/medical-dermatology/topical-corticosteroids/) and [Oral Corticosteroid Treatment](/treatments/medical-dermatology/oral-corticosteroid-therapy/).

Arrange medical review when pain is new, worsening, interfering with sleep, or making eating, drinking, urinating, or sexual activity difficult. Seek prompt care for spreading redness, pus, fever, significant bleeding, an eye symptom, or a mouth sore that persists. A clinician can look for infection, medication reactions, or a different cause alongside lichen planus.

Ask which site is causing the pain, whether a sore needs sampling, how long treatment should be used, and what to do if the medicine irritates the area. Mention every affected body region, including the mouth, scalp, nails, or genital skin.
