Raynaud's Disease Quiz

This is a disorder of unknown origin where there is decreased blood flow to the fingers from blood vessel spasm. Initially, the fingers turn pale when exposed to the cold, then subsequently become swollen, painful and red when warmed.

• Fingers and toes turn from pale blue to purplish-red when in the cold

• Fingers and toes are pale white or blue

• Numbness or abnormal sensation
