Suggest Medication For A Skin Infection

Hello Doctor,

Initially I had some itching above my foot skin, I mean the skin below our Shoe lace. And when I used to scratch it hard, I used to get rashes and after a couple of days they turned into wounds.. Now after around 7 to 8 months, the itching has totally disappeared, but there are some dark spots on both the legs. The right one has most of the dark spots. I need a solution to wipe out these spots.. Is there any Doctor who can help out with this please?
