What Happens If Lichen Planus Is Not Treated?

Lichen planus can cause raised, itchy bumps or flat patches on the skin. Ongoing scratching can break the skin and increase irritation. After active inflammation settles, darker or lighter marks may remain for some time. Lesions in the mouth, genital area, or scalp can cause soreness, discomfort with eating or intimacy, or hair loss in the affected area. Lichen planus is not contagious, but a persistent rash still deserves a clear diagnosis because several skin conditions can look similar.

Arrange a dermatology assessment if the rash is persistent, spreading, very itchy, or affecting sleep. The clinician may examine the skin and mouth and choose treatment according to the sites involved. Options can include Topical Corticosteroids for local inflammation or Oral Corticosteroid Treatment when broader control is needed. Use prescribed treatment as directed and avoid picking, vigorous scrubbing, or unapproved creams.

Seek prompt medical care for painful mouth sores that make drinking difficult, genital sores, rapidly worsening skin, eye symptoms, or signs of infection such as increasing warmth, swelling, pus, or fever. A new changing spot should also be examined rather than assumed to be lichen planus.

Ask which body sites are involved, whether the diagnosis needs confirmation, how long treatment should continue, and what changes would indicate a review. You can also ask how to protect irritated skin and whether mouth or genital symptoms need a separate examination.
