Raynaud’s phenomenon manifests as color changes in your fingers and toes, typically triggered by cold temperatures or stress. These changes usually start with a white phase, followed by blue, then red as blood flow returns.
Numbness, tingling, and pain are common sensations accompanying these color shifts. The severity varies; some experience mild discomfort, while others experience intense pain and significant functional limitations.
Primary Raynaud’s, the most common type, lacks an underlying disease. Secondary Raynaud’s, however, indicates an underlying medical condition such as lupus, rheumatoid arthritis, or certain connective tissue disorders. Smoking, certain medications, and repetitive hand movements also contribute.
Diagnosis involves a physical exam, review of symptoms, and potentially additional tests like blood tests and imaging studies to rule out secondary causes. Your doctor will consider your medical history and symptom severity to establish the correct diagnosis.
