Chronic back pain: the real causes (and what actually works)
Share
Back pain is the world's leading cause of disability and the second most common reason for a GP visit. Yet most proposed solutions treat symptoms without addressing the real cause. Here's what's actually happening in your back — and what works durably.
Understanding chronic back pain
We talk about chronic pain when it has lasted more than 3 months, or when it returns regularly in a predictable pattern — in the evening after a long day, on waking after a restless night, or whenever you sit for too long.
This type of pain isn't an accident. It's the result of an imbalance that has built up gradually, often over years, until it reaches a threshold where the body can no longer compensate.
The 5 real causes of chronic back pain
1. Prolonged immobility
Your spine isn't designed to stay static. Intervertebral discs are nourished by a process of absorption — they take in nutrients when you move and expel them when you're still. After 90 minutes in a fixed position, disc nutrition drops significantly.
This mechanism explains why so many people feel pain after a long day sitting, a long car journey, or an evening on the sofa — even without any physical exertion.
2. Chronic forward flexion posture
Looking at a screen, reading, driving, cooking — most of our daily activities tend to push the head forward and round the shoulders. For every centimetre your head moves forward relative to your shoulders, the apparent load on your cervical spine increases by around 4 kg.
A head tilted at 45° exerts the equivalent of 22 kg on your neck — versus 5 kg in a neutral position. Repeated for hours every day, over years, this imbalance eventually alters the structure of the spine itself.
3. Weak stabiliser muscles
The deep back muscles — multifidus, transverse abdominis — are designed to maintain your posture continuously. But they fatigue. And above all, they weaken progressively if you don't actively use them.
Once muscle weakness reaches a certain level, your body compensates using surface muscles — the trapezius, paraspinals — that aren't built for this work. Result: tension, muscle spasm, and chronic pain.
4. Stress and reflex muscle tension
Chronic stress triggers a real physiological response: your muscles contract in anticipation of a threat that never comes. This permanent tension — particularly in the trapezius, neck and shoulders — creates pain independently of your posture or physical activity.
5. The pain-inactivity cycle
Pain leads to inactivity. Inactivity weakens muscles. Weakened muscles worsen pain. This vicious cycle is one of the main mechanisms by which back pain becomes chronic — and one of the reasons why prolonged rest is contraindicated.
What doesn't work long-term
Painkillers and anti-inflammatories
Useful in acute phases to allow a return to normal activity. Ineffective as ongoing treatment — they mask the pain without correcting the imbalance producing it.
Occasional stretching
Stretching provides temporary relief. But if you immediately return to the same posture for 4 hours, the pain comes back. It treats the symptom, not the cause.
Willpower alone
"I'm going to make sure I sit up straight." Posture is an automatic behaviour managed by the basal ganglia — the most primitive part of your brain. Consciously controlling it over hours is cognitively impossible.
Prolonged rest
Counterintuitive but well-documented: prolonged bed rest worsens chronic pain. Movement — even gentle, even limited — is necessary for disc nutrition and maintaining muscle tone.
What actually works
1. Move regularly, not perfectly
The best posture is the next one. Changing position regularly — even 2 minutes every 90 minutes — is better than searching for the perfect position and holding it for hours.
- Take phone calls standing or walking
- Break up long sitting periods with short walks
- Alternate positions if you have a height-adjustable desk
2. Strengthen your stabiliser muscles
5 minutes a day is enough to start building deep back strength:
- Plank: 3 × 20 seconds
- Superman (back extension lying face down): 3 × 10 reps
- Bird-dog (opposite arm/leg extension on all fours): 3 × 10 reps
3. Fix basic ergonomics
- Screen: top of screen at eye level, 60–70 cm away
- Chair: feet flat, thighs horizontal, back supported in its natural curve
- Lighting: no light source in your direct line of sight
4. Use real-time postural feedback
The most effective solution for correcting posture during daily activities. A sensor worn on the back detects in real time when you slump and sends a gentle vibration. This mechanism bypasses the problem of conscious willpower: within 21 days, most users find they straighten up before they even feel the vibration.
Does your back remind you every evening?
Vertax — 95g, invisible under clothing, 2 hours of wear per day is enough.
A simple protocol to start this week
- 5 minutes of cervical and back stretches
- Quick check of your workstation ergonomics
- 2-minute standing break every 90 minutes
- Stay well hydrated
- 2 hours with the Vertax corrector during sedentary activities
- 5 minutes of muscle strengthening (plank, bird-dog)
- Posterior chain stretches
When to see a professional
- The pain radiates into an arm or leg
- The pain is present at rest, at night, or on waking
- The pain is accompanied by tingling or numbness
- The pain doesn't improve after 3 weeks of management
Chronic back pain is not an inevitable consequence of ageing. It's the predictable result of a sedentary lifestyle that hasn't yet adapted to the physiological needs of the human body. Less immobility. Minimal muscle strengthening. Real-time postural feedback. That's all it takes.
