How will lichen planus affect me?
Lichen planus usually causes itching. The itching can be mild or very bad.
You may have just a few small bumps or you may have many. The bumps may persist for weeks or months, and may return once they go away. Sometimes, after the bumps go away, they leave a dark brown area on the skin. This is more likely to happen in persons of Asian, Hispanic or African heritage. These brown spots are not scars. They will slowly fade away, but it may take many months.
Lichen planus inside the mouth may cause painful sores that make it hard to eat.
