I have itching on my neck n getting irritated by that. N my hands n legs both got small small pimples. Even on my back it's very dark. What it is. One of the doctor said to use ketafung cream one year ago if it appears on my neck. Is it good to use. When I asked about pimples rather than giving medicine he said it is hereditary problem. I'm so pissed off. I really wanna get rid of this. And my leg nails are yellow in colour I'll do pedicure every month I'll keep my leg very neat but why yellow colour appear n in the edge black dirt. Help me to get rid of this please.
