I have had lichen planus for about 7 months now. I had a biopsy confirming the diagnosis. It has been very uncomfortable, and has caused my skin to become raw in some areas. I have tried numerous steroid creams as well as prednisone treatments without much relief. Finally, I tried going to the tanning bed a couple of times, and it is finally cleaing up miraculously fast. I know light therapy is one of the treatments used, but my dermatologist hasn't even talked about it yet. My skin condition was to the point of being debilitating.
