My feet are always red most of the time, and when I'm cold my arms turn purple and my hands. The upper side of my arms always have red dots too.?

? Raynauds/ ?Burgers. It sounds like you are having some type of disease related to spasm of the wall of the arteries in your limbs and is restricting blood flow to those areas. This problem can be made worse by certain medications, smoking and cold exposure. You need to consult your doctor for evaluation.
