Just wandering if anyone has or knows anything about Lichen planus. autoimmune dissorder. I developed this about two years ago . I am not sure how it happened and my doctor has no answers for me either. It began on my wrist very itchy red spotting out breaks and a metalic taste in my mouth. Now from time to time I get outbreaks on both my ankles and I have to treat it with cortosol creams. I am told there is no cure for this only treatment . Can anyone shed a light on this?
