I am over 50 male, in my right leg at the top of Ankle the skin has dotted black spots and in some parts of ankle it covers the ankle, it is not harmful or gives pain but it look odd and dirty, on my left lg ankle it is not so black spotted. I have no B>P or Sugar or any heart disease. I want to get rid of this black spotted right ankle, kindly give some lotion or pills to get rid of this black spot spread on my right ankle.
