Hi I am having unique skin disease termed' pityriasis lichenoides chronica' from last 2. 5years. I am having skin rashes all over body except face and scalp which results into itching in case skin is let dry. Initially I tried ayurvedic treatment for few months and later allopathic treatment for close to 2yrs now, however I don' t see any difference. It hasn' t increased but there is no reduction in already present rashes. I am not allergetic to anything &neither has any heredity problem. Can you help me with the reason of having this skin disease and further a solution to this please? thanks,
