Hi. Greetings. It's a little amusing when you day no doctor understands; please send me the pictures of the lesions on follow up private chat or on email at govindmittalatgmail.com or you could come down for a consult if you are from Bangalore and we'll try to understand your issue. What your history suggests is that u could be having a variant of a condition called pigmented purpuric dermatosis or alternatively something called devils pinch which is like a condition with simple bruising and not harmful . Warm regards, Dr Govind S Mittal, excel care hospital, Bangalore.
