I have these weird dark spots since last 2 years probably.One of these initially wasn't a dark spot it was some infection or something and a lot pus used to come out and it used it itch a lot. I consulted a doctor and he gave me some cream, anti fungal I think. It became fine and only a dark spot was left there, I thought it would gradually go away.. But few days later I found that I have 4 such spots of size approx.2 cm each. 2 years later they are still the same. What to do? Right leg is fine
