What is raynaud's?
Raynaud's phenomenon is exaggerated vasoconstriction of fingers and toes in response to cold or stress — causing color changes (white, blue, then red) and discomfort. Affects about 5% of US adults.
Primary Raynaud's is benign and idiopathic. Secondary Raynaud's is associated with autoimmune diseases (scleroderma, lupus) and warrants further evaluation.
Do I have raynaud's? Common signs
If most of these describe what you're experiencing, telehealth may be a good next step:
What causes it
Exaggerated sympathetic nervous system response to cold/stress. Primary: idiopathic, common in young women. Secondary: autoimmune diseases (scleroderma, lupus, Sjögren's), certain medications (beta blockers, migraine meds), vibration injury, smoking.
Is it contagious?
No.
If episodes include skin sores or ulcers, are asymmetric, or affect just one or two fingers — it's likely secondary and needs autoimmune workup.
Can it be treated online?
Routine primary Raynaud's is well-suited to telehealth. Suspected secondary Raynaud's (ulcers, asymmetric episodes, abnormal nailfold capillaries, systemic symptoms) needs in-person rheumatology workup.
How raynaud's is treated
Conservative first: warm gloves, hand warmers, keep core warm, avoid triggers. Calcium channel blockers for moderate-severe: amlodipine, nifedipine XR. Topical nitroglycerin for individual digits. Treat underlying autoimmune disease if secondary. Avoid triggering medications and smoking.
Self-care while you wait
- Layer up — keep CORE warm (jacket, hat) not just hands
- Heated gloves/mittens
- Hand warmers
- Avoid sudden cold exposure
- Don't smoke — nicotine causes vasoconstriction
- Limit caffeine if it triggers
- Stress management
- Warm car before getting in
- Keep gloves in car, office, home
How long does it last?
Primary Raynaud's often persists for life but stable. Secondary depends on underlying disease.
Frequently asked questions
Will I lose a finger?
Primary Raynaud's doesn't typically cause tissue damage. Secondary can if untreated.
Should I worry about scleroderma?
If you have ulcers, abnormal nailfold capillaries, asymmetric Raynaud's, or systemic symptoms — yes, get evaluated. Otherwise rare.
Can I exercise outside in winter?
Yes — but layer well, especially core. Warm up indoors first.
Do I need medication?
If frequent severe episodes or affecting function/work, yes. Mild cases often manage with lifestyle.
Will it get worse with age?
Primary Raynaud's usually stable. Secondary depends on disease progression.
