Ten years of low back pain with a normal scan: what to do about non-specific low back pain
Male, 46. Pain for 10 years. Prolonged sitting plus intermittent heavy lifting.
The MRI showed only mild degeneration, yet the pain never stopped for ten years. Two things are most feared in this kind of back pain: passive treatment without exercise, and cutting back all activity out of fear of the pain.
History and prior work-up
Chronic lumbosacral pain for 10 years, worse with prolonged sitting and standing. Pain was located slightly left of the midline, without radiation to the buttock or leg; morning stiffness lasted under 30 minutes and eased with activity. Lumbar MRI showed only mild disc degeneration, with no definite structural change.
Physiotherapy, injections, and bone-setting manipulation had been tried with short-lived effect; NSAIDs were used intermittently. Activity had been reduced because of the pain, and physical fitness declined.
Examination and pattern differentiation
The main pattern is cold-damp lumbago, with kidney deficiency from the long illness — a mixed deficiency and excess picture. Pain worse with cold and eased by warmth indicates cold-damp; soreness, weakness, and worsening on exertion indicate kidney deficiency. Classical internal medicine divides lumbago into four patterns — cold-damp, damp-heat, blood stasis, and kidney deficiency — and in this case cold-damp with kidney deficiency is the guiding pattern.
- Lumbar range of motion slightly limited; tenderness over the lumbar muscles and sacroiliac region; normal lower-limb strength and sensation.
- Tongue pale with a thin white greasy coat; pulse deep and tight; aversion to cold with preference for warmth; average sleep, low mood.
Treatment pathway
- External treatment first: Shenshu (BL23), Dachangshu (BL25), Mingmen (GV4), Yaoyangguan (GV3), Ciliao (BL32), Huantiao (GB30), Weizhong (BL40), Kunlun (BL60), Taixi (KI3); acupuncture combined with moxibustion or needle warming (moxa on the needle) — particularly suited to cold-damp and kidney deficiency; tuina to release the thoracolumbar fascia and iliopsoas, with caution about forceful thrusting maneuvers. Two to three times weekly.
- Herbal decoction as support: for cold-damp, Ganjiang Lingzhu Decoction or Duhuo Jisheng Decoction; for kidney deficiency, the intent of Jinkui Shenqi Pill or Zuogui Pill. Dosage is set at the in-person consultation.
- Classical reference: Zhang Zhongjing's Jin Gui Yao Lue used Ganjiang Lingzhu Decoction for shen zhu (cold-damp binding at the lumbar spine).
- Functional training (essential): transversus abdominis and multifidus activation, glute bridges, McKenzie extension exercises, and the Baduanjin move 'two hands hold the feet to strengthen the kidneys and waist'; gradually restore everyday activity levels and avoid prolonged bed rest.
- Concurrent management: education on sleep and sitting posture and on lifting technique; weight-loss advice where overweight.
Re-evaluation
| Timepoint | Pain (activity / rest) | Morning stiffness | Daily activity level | Training adherence |
|---|---|---|---|---|
| Baseline at first visit | 6/3 | 20 min | Low | Not started |
| Week 4 | 4/2 | 10 min | Increased | 4 sessions/week |
| Week 8 | 3/1 | 5 min | Near normal | Daily |
Acupuncture and tuina open the pain threshold; training is what keeps the window open.
Follow-up and advice
Goals are framed as 'lower pain intensity, restore functional activity, reduce reliance on painkillers'. Progressive numbness or weakness in the legs, numbness in the saddle region, or changes in bladder or bowel function require immediate emergency care (red flags for cauda equina syndrome).
