Patient Education: Raynaud’s Syndrome
What It Is
Raynaud’s Syndrome is a condition that affects blood flow to certain parts of the body, usually the fingers and toes. When you get cold or feel stressed, the small blood vessels in these areas tighten (spasm), which reduces blood flow. This can cause your skin to change color, feel numb, or hurt.
Causes and Risk Factors
Triggers: Cold weather, air conditioning, stress, or emotional upset.
Primary Raynaud’s: Happens on its own, usually less serious.
Secondary Raynaud’s: Linked to other health problems like lupus, scleroderma, or certain injuries.
Risk factors:
Being female
Age 15–40
Family history of Raynaud’s
Smoking
Repetitive hand use (typing, vibrating tools)
Certain medicines that narrow blood vessels
Signs and Symptoms
Early warning signs: Fingers or toes turn white, then blue, then red
Tingling or numbness
Cold feeling in fingers or toes
Pain or throbbing as blood returns
Sometimes ears, nose, lips, or nipples can be affected
Possible Complications if Untreated or Not Following Care Plan
Permanent damage to skin and tissues
Ulcers (sores) that heal slowly
In rare cases, loss of part of a finger or toe (gangrene)
Increased risk of infection in affected areas
Treatment and Self-Care Measures
Goals: Improve blood flow, prevent attacks, and protect skin.
Stay warm:
Wear gloves, warm socks, hats, and scarves in cold weather.
Use mittens instead of gloves for better warmth.
Warm up your car before driving in winter.
Avoid sudden temperature changes:
Keep home warm in winter.
Use insulated cups for cold drinks.
Manage stress:
Practice deep breathing, meditation, or gentle exercise.
Protect your skin:
Moisturize daily to prevent cracks.
Avoid injuries to hands and feet.
Quit smoking: Smoking narrows blood vessels and makes symptoms worse.
Common Types of Medications
Calcium channel blockers (ex: nifedipine, amlodipine): Help open blood vessels. Side effects: swelling in feet/ankles, headache, flushing.
Vasodilators (ex: nitroglycerin ointment): Help relax blood vessels. Side effects: headache, dizziness.
Alpha blockers (ex: prazosin): Reduce vessel tightening. Side effects: low blood pressure, dizziness.
Dietary Needs
Eat a balanced diet rich in fruits, vegetables, whole grains, and lean protein.
Limit caffeine and alcohol (can cause blood vessel spasms).
Stay hydrated — dehydration can worsen symptoms.
Lifestyle Changes
Dress in layers during cold weather.
Warm hands/feet before going outside.
Exercise regularly to improve circulation.
Avoid vibrating tools and repetitive motions when possible.
Safety Considerations
Test water temperature with your elbow, not fingers, to avoid burns when your skin is numb.
Keep emergency heating packs available.
Avoid walking barefoot, especially on cold floors.
Prevention and Maintenance Tips
Keep regular follow-up appointments with your healthcare provider.
Monitor for changes in skin color, temperature, or wounds.
Treat even small cuts quickly to prevent infection.
Learn your personal triggers and avoid them.

Skin becomes cold, hard, and you cannot move the area.
