Raynaud’s Phenomenon

Share on social media

Raynaud’s Phenomenon (RP) results when there is a decrease in blood flow to the fingers and toes when someone is exposed to cold weather or stress, due to an exaggerated constriction in blood vessels. RP can also affect your ears, nose, and even nipples. The fingers or toes typically change color, and this can cause numbness, tingling, and pain. These symptoms occur intermittently and tend to resolve spontaneously on rewarming. Learn more.
