Raynaud phenomenon is a condition that affects your blood vessels (the tubes that your blood flows through). It causes your blood vessels to narrow, which decreases blood flow. This is called a Raynaud episode or "attack." The attacks usually affect your fingers and toes, causing them to become cold and numb. generated by SI from cited sources · general information, not a diagnosis · consult a health professional
