I have lichen Planus Orally, in the genitalia , and on my skin. Some form of anti inflammatory is regularly prescribed! There is no cure but you cam maintain a reasonably pain free life if you don’t let the lesions overwhelm you. I see 3 different Dr’s as they each treat a different body part. But I am reasonably pain free and am able to eat. Best of luck. My Gynecologist refereed to LP as the Trifecta. I have had the disease for about 37years. The treatment is much better now! Foods that aggravate my symptoms are: Any small amount of dairy, any nuts, acid foods and alcohol. Best of luck!
