How do you diagnose Reynolds phenomenon?

Answer 1

Reynolds phenomenon, often referred to as Raynaud's phenomenon, is diagnosed primarily through a patient's clinical history and symptoms, which include episodic attacks of color changes in the fingers or toes in response to cold or stress. A physical examination may reveal pallor, cyanosis, and erythema during an attack. In some cases, additional tests such as nailfold capillaroscopy or blood tests may be conducted to rule out underlying conditions, such as autoimmune disorders. A detailed history of symptoms and triggers is crucial for accurate diagnosis.
