Sciatica

Key Points

First, what cannot wait

Understanding the Condition

Sciatica is less a "disease" than an alarm along a "route": radiating pain, tingling or burning from the low back and buttock down to the calf and foot. The most common cause is a lumbar disc herniation or spinal stenosis irritating a nerve root; muscular entrapment such as a tight piriformis can also "pinch" the nerve.

Key distinction: disc-type pain worsens with bending and prolonged sitting; piriformis-type is provoked by sitting pressure on the buttock and specific straight-leg angles. Their treatments differ 鈥 which is why physical examination at the first visit is essential.

Why It Keeps Coming Back

After the flare, people unconsciously tilt and shorten their stride to "dodge" the pain; over time the lumbar-gluteal muscles fall out of balance, fixing the traction and irritation of the nerve root 鈥 pain becomes a pattern, not just a symptom.

Prolonged bed rest does not help nerve recovery: moderate movement promotes the nerve root's mobility and blood supply 鈥 where modern rehabilitation and the TCM idea of "moving to master stillness" meet.

Our Pattern-Based Approach

TCM calls it "lumbago-sciatic pain" or "bi syndrome", along the bladder and gallbladder channels. Patterns: cold-dampness obstruction 鈥 cold heavy pain, worse in cold and dampness; blood stasis 鈥 fixed stabbing pain, worse at night; damp-heat pouring down 鈥 burning pain, bitter taste, heaviness; liver-kidney deficiency 鈥 weak aching of long duration.

Acupuncture uses Dachangshu (BL25), Huantiao (GB30), Weizhong (BL40), Yanglingquan (GB34), Chengshan (BL57) and Kunlun (BL60) 鈥 "for lumbar pain seek Weizhong"; deep needling Huantiao often draws qi sensation radiating down the leg (a good sign), with lumbar-gluteal tuina and cupping. We equally stress McKenzie extensions and nerve-gliding drills 鈥 putting the "trapped nerve" back on a freely sliding track.

The Evidence

• An individual-patient-data meta-analysis of ~18,000 participants found acupuncture significantly superior to sham acupuncture and usual care for chronic pain, including back pain.
  — Vickers et al., 2012, Archives of Internal Medicine (now JAMA Internal Medicine)
• A Cochrane systematic review found acupuncture more effective than no acupuncture for chronic non-specific low back pain 鈥 the main backdrop of sciatica.
  — Cochrane Database of Systematic Reviews, Acupuncture for low-back pain, 2013

What to expect: first visit to follow-up

1. First visit 路 about 40 minutesDetailed history, neurological examination (straight-leg raise, strength, sensation and reflexes to localize the affected root), pulse and tongue 鈥 distinguishing disc-type from muscular entrapment, systematically screening red flags, and recommending imaging when indicated.
2. Plan discussion 路 same dayWe explain the affected-root assessment, planned points and frequency, activity advice and current contraindications, and exactly when to return urgently or accept referral.
3. Weeks 1-4One to two acupuncture and tuina sessions weekly. Targets in order: smaller radiating area, less night pain, restored gait. You record the furthest point the pain reaches (foot/calf/below knee) 鈥 the retreat of this "boundary" is the most intuitive yardstick of progress.
4. Weeks 4-8 路 reviewAssessment by radiating range, numbness and strength: continue, adjust points and technique, or move into an exercise-led maintenance phase; non-responders are sent promptly for imaging and specialist consultation.

Course of care and follow-up

• Assessment usually runs in 4-6 week cycles
• Even after radiating pain fades, 4-8 weeks of consolidation follow 鈥 preventing the relapse of "pain leaves first, nerve not yet recovered"
• Then follow-up every 2-4 weeks until function fully recovers
• Strength and sensation are monitored throughout; any sign of cauda equina syndrome or progressive deficit triggers immediate emergency referral

When to Seek Care

Before your visit:

• After 1-2 days of brief rest in the acute phase, resume moderate activity early
• Avoid soft sofas and bending to lift; support the low back when sitting
• Prone McKenzie extensions (if your therapist confirms they fit your type)

Consider an in-person consultation if:

• Leg pain or numbness not easing after 4-6 weeks, or repeatedly flaring
• Clear leg weakness (difficulty lifting the foot) or spreading numbness
• Saddle numbness or bowel/bladder dysfunction 鈥 emergency care immediately

Supportive Care

• Exercise: McKenzie extensions plus nerve-gliding (straight-leg slider), under guidance
• Ba Duan Jin: gentle stretches like "two hands hold the feet"; no deep forward bending in the acute phase
• Posture: lumbar support when sitting; stand up regularly on long drives
• Warmth: keep the lumbar-gluteal region and legs warm; warm packs help
