Raynaud’s Syndrome
Raynaud’s phenomenon is a vascular disorder that causes blood vessels in the fingers and toes to constrict. The affected areas can turn pale and blue due to lack of blood flow and can be painful when blood flow returns. The etiology of this condition is unknown and can be considered a primary disorder or it can occur due to another condition.
Studies have demonstrated a higher rate of Raynaud’s phenomenon in those with migraine compared to those without1,2 and have found that women are more affected.
