I have unexplained marks on both of my lower legs?

Hello. I have unexplained marks on both of my lower legs. I had pain in my right leg earlier last week. But not for sure if one is connected to the other. I have been feeling sick and recently just had sinus surgery in dec. And gallbladder removed in june. About 3 days ago I noticed marks on both legs. Its it something i should be worried about? What type of doctor should I see and will this go away. Please help
