What symptom is associated with Raynaud's phenomenon?

1. Intermittent chest pain

2. Color changes of the digits

3. Edema in the lower extremities

4. Rest pain in the legs

The correct answer is: Color changes of the digits

Raynaud's phenomenon is characterized by episodic attacks where the small blood vessels in the fingers and toes constrict in response to cold temperatures or stress, leading to specific color changes in the digits. During an episode, the affected areas may turn white (due to lack of blood flow), blue (due to deoxygenated blood), and eventually red (as blood flow resumes). This classic triad of color changes is a hallmark sign of Raynaud's and helps distinguish it from other conditions. The other options do not align with the characteristic presentations of Raynaud's phenomenon. Intermittent chest pain is more commonly associated with cardiovascular issues, while edema in the lower extremities is typically linked to circulatory or heart problems. Rest pain in the legs often indicates peripheral arterial disease. Therefore, color changes of the digits directly relate to the pathophysiology of Raynaud's phenomenon and are the primary symptom of this condition.
