Skin, Hair and Nail Problems

Hi, My dad has some kind of lump formations under skin since a year and they are not going even after applying some creams and they remain as dark toned scars. These lumps can be felt and seen clearly in both hands and legs. Now it started on the feet too. Slowly they are spreading and i am afraid he may not be able to walk if this continues.   Visit to few skin specialists hasn't helped much. Kindly assist. Regards, Sunil.
