Hi,I am Dr. Shanthi.E (General & Family Physician). I will be looking into your question and guiding you through the process. Please write your question below.
My knuckles on my left hand have got dark all of a sudden. I have been ignoring it for about 2 weeks but it's still there like a permanent mark. If i try to scratch it off, then it becomes white which is the same as scratching any other part of my skin. Only on my left hand! Please diagnose it, someone!
