Raynaud’s syndrome
Last updated: 2026-09-20 · Prepared by licensed TCM physicians · Updated 2026-09
Key Points
Raynaud’s phenomenon is a paroxysmal color change of the fingers (sometimes toes) — pallor → blueness → redness — triggered by cold or emotional stress, with numbness, tingling or pain. It is split into primary (benign) and secondary (linked to connective-tissue disease), and the type must be clarified first.
- Typical attacks are cold- or stress-triggered: finger goes white, then blue, then red on rewarming
- Primary is common and benign; secondary may signal scleroderma, lupus and needs checking
- Keeping warm and avoiding triggers is the base; acupuncture and care are adjunctive for circulation
- Digital ulcers, one-sided onset or late onset are "red flags" — see rheumatology promptly
First, what cannot wait
- Ulcers, blackening or necrosis of a digit — seek care now (tissue ischemia)
- Sudden one-sided limb pain, pallor or blueness with absent pulse — suspect embolism/acute ischemia, emergency now
- Chest pain or breathlessness with finger color change — rule out combined cardio-pulmonary issue, seek care
- A digit wound that will not heal and rapidly blackens — go to surgery/vascular at once
- One-sided or late onset (>40 years)
- Skin hardening, pitting scars at fingertips or nail-fold changes
- With joint pain, dry eyes/mouth, rash — rheumatology screen promptly
Understanding the Condition
Think of the small finger vessels as "over-sensitive switches": in cold or stress they spasm, blood supply drops, and the finger first blanches (no blood), then turns blue (low oxygen), then flushes red as it rewarms.
It is not simply "chilblains" — it is an over-reaction of vessels to cold and emotion. The key is first telling primary (just sensitive vessels) from secondary (an underlying immune disease behind it).
Why It Keeps Coming Back
Because secondary Raynaud can hide a serious signal — scleroderma, systemic lupus — best caught early. Treating everyone as "minor" misses that group.
Triggers (cold, stress, smoking) live in daily life; just "enduring" makes attacks more frequent. Warmth, quitting smoking and relaxation clearly cut attacks, and care helps peripheral circulation.
Our Pattern-Based Approach
A clinically common adjunctive approach "warms the channels and disperses cold, moves blood and unblocks collaterals, boosts qi and yang": cold congealing the vessels (cold-triggered, painful); yang deficiency (cold limbs, chill); qi stagnation with blood stasis (emotion-triggered, dusky cyanotic skin, dark tongue).
Acupuncture often uses Hegu (LI4), Waiguan (SJ5), Zusanli (ST36) and Yangchi (SJ4) to warm and unblock the channels and raise yang, with strict warmth and smoking cessation. This remains adjunctive; if secondary is suspected, rheumatology must diagnose first.
Common patterns and treatment directions
| Pattern | Typical presentation | Approach |
|---|---|---|
| Cold congealing the vessels | Cold-triggered, finger pallor and stinging, eased by warmth | Warm channels and disperse cold: Hegu (LI4), Waiguan (SJ5), Yangchi (SJ4), emphasis on warmth |
| Yang deficiency | Cold limbs, chilliness, fatigue, easy attacks | Warm yang and unblock vessels: Zusanli (ST36), Guanyuan (CV4), Qihai (CV6) |
| Qi stagnation with blood stasis | Emotion-triggered, dusky cyanotic skin, dark tongue, stabbing | Move qi and blood: Neiguan (PC6), Taichong (LR3), Geshu (BL17) |
| Blood deficiency with cold congealing | Numb cold digits, pale face, thin pulse | Nourish blood and disperse cold: Xuehai (SP10), Sanyinjiao (SP6), Hegu (LI4) |
| Stasis obstructing the collaterals | Frequent attacks, dusky purple skin, long-standing | Invigorate blood and unblock: ashi points, Geshu (BL17), Xuehai (SP10), warm needling |
Patterns are determined in person. This list is for orientation only and is not a self-diagnosis tool.
What to expect: first visit to follow-up
- First visit · about 40 minutesWe take history, pulse, tongue and trigger check, and assess for "red-flag" features; if secondary is suspected, refer to rheumatology first to clarify the type before care.
- Plan discussion · same dayWe explain the pattern and adjunctive role, the warmth/smoking-cessation focus, and when to return to specialty care.
- Weeks 1-4One to two sessions per week, focused on fewer attacks and better peripheral circulation; you keep a trigger and attack diary.
- Week 4-8 · first reviewCompare diary before and after; decide to continue, adjust points or move to maintenance.
Course of care and follow-up
- Assessment usually runs in 4-8 week cycles
- Once stable, care may shift to maintenance every 2-4 weeks
- Re-assess yearly or with trigger/constitution change
- We work with rheumatology throughout: refer at once if secondary is suspected
When to Seek Care
Before your visit:
- Keep warm strictly: gloves, socks, scarf on hand; avoid sudden cold and cold water
- Stop smoking and avoid secondhand smoke; moderate caffeine; avoid trigger drugs (some migraine/cold remedies contain vasoconstrictors)
- Stress management: relaxation training to reduce emotion-triggered spasm
Consider an in-person consultation if:
- One-sided onset, new after age 40, or only individual fingers affected
- With digital ulcers, skin hardening, joint swelling or rash
- With positive autoantibody family history, or rapidly worsening — see rheumatology
Supportive Care
- Warmth: layer clothing, hand warmers, avoid direct AC and cold rooms
- Habits: quit smoking fully, limit caffeine, regular exercise to aid circulation
- Skin care: keep hands and feet moisturized; prevent cracks and frost injury
- Emotions: tension triggers attacks; breathing relaxation and a regular rhythm help
FAQ
Is Raynaud just "cold hands"?
Not quite. Pure primary usually starts young, bilateral and symmetric, and improves with warmth. But one-sided, late-onset, with digital ulcers or skin hardening may signal secondary (immune disease) and must be checked by rheumatology — not just treated as "cold hands".
Can acupuncture "cure" Raynaud?
We do not promise a cure. Acupuncture aims to warm the channels, improve peripheral circulation and reduce attack frequency and discomfort, with warmth and smoking cessation. For secondary cases, diagnose and treat the cause first; care is only adjunctive.
