I know how it feels since a friend of mine also suffered the same thing.. She too had this skin disorder and it developed into scaly patches.It pained her enough and she did try all sorts of treatments but didnt respond well to any. Finally, her father put her on homeopathy and she showed a marked improvement. Now she is continuing with this treatment and hopes slowly and steadily she will be alright. She has to keep patience and strong will power to overcome this and come out perfectly fine but the diagnosis and the medications should be just right. For more info on lichen planus please see here
