I have black pigmentation from toe till knee. Initially it was only near the ankel then it spreaded till knee. There is no itching. burning sensation. Its been 2 yrs. I applied neem oil and several creams but didn't find any effect. Pls suggest me what could be the reason for it and how can it be cured? Are these pigments in the upper skin or deeper? It is mostly in the front side of both the legs.
