My toes lose color and get cold quickly when I go outside. Is there a test I should have done on myself?

Raynaud's, possibly. In raynaud's phenomenon, fingers or toes turn white or blue in cold, then red when warmed.It is due to abnormal degree of constriction of arterioles (very small arteries).It can occur by itself, but can be associated with autoimmune diseases like systemic sclerosis. A complete history of your symptoms and a physical exam by your doctor along with blood tests should provide you w a definite answer.
Yes. You probably have a vasospsasm and should be tested for raynauds disease or phenomena.
