When to Contact a Medical Professional
Call your doctor for an appointment if:
Your fingers change color and the cause is not known
Fingers or toes turn black or the skin breaks
What to Expect at Your Office Visit
The doctor will perform a physical examination, which will include close examination of the hands, arms, and fingers.
The doctor will ask questions about your medical history and symptoms, including:
Did the fingers or toes suddenly change color?
Has the color change occurred before?
Does cold or emotion cause the fingers or toes to turn white or blue?
