Yellow skin blotches and red spots, should I go see a doctor? - skin blotches more condition_symptoms

More recently realized that I appear yellow spots on both shoulders. I also have little red dots on the hands and arms. To search for the most of them no bigger than pin-pricks, but they exist for months. All ideas what could be causing this?
