The patient
- Age and sex
- 58 years · M
- Chief complaint
- A 58-year-old man with four years of dull low back pain, worse with cold and damp, better with heat and gentle movement, forcing him to get up slowly in the mornings.
- Tongue
- Pale, swollen body with teeth marks and a white, moist coating.
- Pulse
- Deep and weak pulse, especially in the Chi (尺) position on both wrists.
Symptoms
- Dull, constant low back pain without radiation into the leg
- Morning stiffness that eases after twenty minutes of activity
- Cold and weak sensation in the lower back and knees
- Needing to urinate two or three times at night
- Background tiredness and less tolerance for exertion than a few years ago
- Pain increases on rainy days and with the first cold weather
Warning signs to rule out
- Leg weakness, saddle numbness or loss of bladder or bowel control. → Immediate emergency care for suspected cauda equina syndrome. This is not low back pain that can wait for the next session.
- Low back pain with fever, weight loss or a cancer history, or pain that does not change in any position. → Imaging before treatment. Mechanical pain always changes with position; pain that does not requires looking further.
- Sudden low back pain after minimal effort in an older patient or one on long-term corticosteroids. → Rule out a fragility vertebral fracture with imaging before applying any manual technique.
Case resolution
Think through the pattern first, then expand the resolution
- Pattern
- Kidney Yang Deficiency with Cold-Damp obstruction (Bi)
- Meridians involved
- Kidney, Bladder, Governing Vessel
- Pathogenic factors
- Kidney Yang vacuity, Cold, Dampness
The lower back is the dwelling of the Kidney: when Yang wanes with the years, it no longer warms and supports the region, and a dull pain appears that improves with heat and movement rather than rest. That vacuity is also the door through which Cold and Damp settle in, which explains the worsening with rain. Nocturia and cold knees confirm the problem is not in the back but in the root that supports it.
Differential diagnosis
Shares: Chronic low back pain of years' standing.
Sets it apart: Blood stasis gives stabbing, fixed pain, worse at night and with pressure, with a history of trauma and a purplish tongue. Here the pain is dull, improves with movement and the tongue is pale.
Shares: Low back pain that worsens in humid weather.
Sets it apart: Damp-Heat presents with burning, scanty dark urine and a yellow greasy coating, and worsens with local heat. This patient improves with heat, which settles the differential.
Shares: Dull low back pain with weak knees and nocturia.
Sets it apart: Yin vacuity gives afternoon heat, night sweats, dry mouth and a red tongue without coating, and the patient seeks cool. Here he seeks heat and the tongue is pale and swollen: the same organ, the opposite pole, and incompatible treatments.
Treatment
Principle: Warm and tonify Kidney Yang, dispel Cold and Damp, and unblock the local channel.
| Point | Role | Technique |
|---|---|---|
| BL23 | Kidney Back-Shu: the root point of this low back pain, always with moxa. | Perpendicular 0.8-1 cun with moxa, tonifying. |
| GV4 | Mingmen, the Gate of Life: the source of Yang warmth when the patient is cold from within. | Oblique upward 0.5-0.8 cun, or fifteen minutes of moxa. |
| BL40 | Command point of the back: the mandatory distal point in any low back pain. | Perpendicular 1-1.5 cun, avoiding the popliteal vessels. |
| KI3 | Kidney Yuan-source: it sustains the tonification of the root between sessions. | Perpendicular 0.5-0.8 cun, tonifying. |
| BL60 | Taiyang Jing-river: it moves the channel from a distance without draining an already weak area. | Perpendicular 0.5 cun. Contraindicated in pregnancy. |
| CV4 | Guanyuan: it reinforces Yuan Qi from the front, so tonification does not rest on the back alone. | Fifteen minutes of moxa, or perpendicular 0.8-1.2 cun with an empty bladder. |
Formula: You Gui Wan. Warms and tonifies Kidney Yang for the background of the picture. When local Cold-Damp dominates over the vacuity, Du Huo Ji Sheng Tang covers both sides better at once.
- Frequency
- One session weekly for eight weeks, then monthly maintenance through the cold months. Years of Yang vacuity are not corrected in a month, and improvement reaches the stiffness before the pain.
Home care
- Moxa on BL23 for ten minutes, three times a week through the winter.
- A kidney warmer or a long shirt tucked in: an exposed lower back is the entry route for Cold.
- Walk thirty minutes a day; prolonged rest worsens this pain rather than easing it.
- No sitting on stone or cold surfaces, and avoid showering right before going out into the cold.
Progress
- Session 1 · day 0 Constant pain 6 out of 10, twenty minutes to get going in the morning and three night-time voids. Moxa on BL23 and GV4, needling BL40 and KI3. Home moxa is taught and covering the lower back is emphasized. Pain drops to 4 out of 10 for three days and the area feels warmer, but morning stiffness is unchanged.
- Session 3 · week 3 Pain improves, but morning stiffness and heaviness persist and coincide with a rainy week. SP9 and BL39 are added to drain Dampness: warming without draining leaves the heaviness intact. The morning start-up goes from twenty minutes to under five within two weeks.
- Session 6 · week 6 Pain 2 out of 10 and a single night-time void. He reports having stopped walking because it no longer hurts. CV4 with moxa is added and the plan is corrected: in this pattern movement is part of the treatment and dropping it guarantees relapse. He resumes the daily walk and keeps the pain below 2 out of 10.
- Session 8 · week 8 No pain at rest and only mild discomfort after long spells of standing. Knees less cold. Treatment ends, with home moxa and one session a month while the cold lasts. He gets through the winter without a single disabling episode, for the first time in four years.
- Discharge
- Treatment ends once the morning start-up is under five minutes and he manages a normal day, with home moxa already part of his routine. The goal is not absence of pain but that the weather stops dictating.
- Watch for relapses
- The first cold of autumn and rainy weeks. The warning arrives as cold knees and nocturia before it arrives as pain: resuming moxa is enough at that stage.
