A simple blood test can detect either, and both are treatable. But, if frostiness is paired with pain, burning, or drastic whitening of fingers or toes, it could be an indication of peripheral vascular disease (spasm of the arteries), which is more serious; you should see your doctor ASAP.
One possible cause of numbness in the finger tips is lack of blood flow. This can be caused by something called Raynaud's phenomenon. Raynaud's phenomenon is a symptom that is seen in some disease such as lupus where blood flow doesn't reach the tips of the fingers, especially in cold weather. Another common cause of numbness in the finger tips is uncontrolled diabetes. High blood sugars caused by diabetes damage nerves in the finger tips and toes. If you also have nerve problems in your feet, then this could be an explanation. I suggest that you schedule an appointment with your primary care physician.
