Raynaud’s disease is a vascular condition that affects blood flow to the fingers, toes, ears, and nose, causing them to become painfully cold, numb, and discolored in response to cold temperatures or stress. While often mild, severe cases can lead to ulcers, infections, and tissue damage if circulation does not return properly.
At Vascular Surgery Associates, our vascular specialists in Los Angeles and Santa Monica provide comprehensive diagnosis and treatment for Raynaud’s disease, helping patients manage symptoms and prevent complications. With advanced vascular care and personalized treatment strategies, we offer solutions to improve circulation and enhance quality of life.
What is Raynaud’s Disease?
Raynaud’s disease is a condition in which small blood vessels constrict excessively, limiting blood flow to the extremities. These episodes are often triggered by cold temperatures, stress, or emotional reactions. During an episode, the affected areas may go through a three-phase color change:
White (Pallor)
Due to reduced blood flow
Blue (Cyanosis)
Lack of oxygen leads to discoloration
Red (Hyperemia)
Blood rushes back, causing warmth and tingling
There are two primary types of Raynaud’s:
Primary Raynaud's Disease
Occurs without an underlying condition and is typically less severe
Secondary Raynaud's Syndrome
Associated with autoimmune diseases, vascular disorders, or other medical conditions and may cause more severe complications
Common Symptoms of Raynaud’s Disease
Individuals with Raynaud’s disease may experience:
- Cold fingers or toes that turn pale or blue
- Numbness, tingling, or throbbing pain in the affected areas
- Skin discoloration that occurs in response to temperature changes
- Ulcers or sores on the fingers or toes in severe cases
While mild Raynaud’s disease is manageable, persistent or severe episodes should be evaluated by a vascular specialist.
Who is at Risk for Raynaud’s Disease?
Several factors contribute to the development of Raynaud’s disease, including:
Cold Exposure
Triggers excessive narrowing of blood vessels, leading to circulation issues
Emotional Stress
Causes blood vessels to constrict, reducing blood flow to the extremities
Smoking
Damages arteries and increases the risk of circulation problems over time
Autoimmune Diseases
Conditions like lupus, scleroderma, and rheumatoid arthritis affect vascular health
Repetitive Hand Movements
Prolonged use of vibrating tools or repetitive actions can impact circulation
Diagnosing Raynaud’s Disease
At Vascular Surgery Associates, we use advanced vascular testing to diagnose Raynaud’s and assess potential underlying causes. Diagnostic tools include:
Nailfold Capillaroscopy
Examines small blood vessels under a microscope
Doppler Ultrasound
Assesses blood flow and vascular abnormalities
Cold Stimulation Test
Evaluates how quickly blood flow returns after cold exposure
Effective Treatment Options for Raynaud’s Disease
While there is no cure for Raynaud’s disease, treatment focuses on symptom management and preventing complications.
Lifestyle Modifications
- Keeping hands and feet warm and dry
- Avoiding caffeine and smoking, which constrict blood vessels
- Managing stress to reduce episodes
Medications for Circulatory Support
- Calcium channel blockers Help relax blood vessels
- Vasodilators Improve blood flow and prevent attacks
- Alpha blockers Reduce nerve signals that trigger vasoconstriction
Advanced Procedures for Severe Cases
Botox injections
Can help relax blood vessels in extreme cases
Sympathectomy surgery
A nerve-blocking procedure for severe Raynaud’s

Common triggers include cold weather, emotional stress, caffeine, and smoking.
Wearing gloves, keeping warm, managing stress, and avoiding smoking and caffeine can help minimize episodes.
Yes, secondary Raynaud’s is often associated with autoimmune diseases like lupus and scleroderma.
