Chronic Low Back Pain: The Trigger Is Not Always the Cause

“My back pain started after a six-hour flight.”

We hear explanations like this often. The pain appeared after a long flight, a road trip or an unusually long day at a desk, so it seems logical to assume that this one event caused the problem.

Sometimes pain does have a clear cause, such as a fall, sports injury, collision or other trauma. But chronic or recurring low back pain is often more complex. In fact, the World Health Organization reports that about 90% of low back pain is non-specific, meaning that no single disease or structural problem can confidently explain it.

The Last Straw, Not Always the Whole Story

A long period of sitting can certainly aggravate the lower back. It reduces movement, keeps the body in one position and may place more demand on tissues that are not currently prepared to tolerate it.

However, the flight or drive may be the trigger—the last straw—rather than the complete cause.

Before that painful episode, several factors may already have been affecting the body’s tolerance, including:

• low activity or reduced physical conditioning

• limited movement variety throughout the day

• strength or endurance deficits

• previous episodes of back pain

• repeated physical demands at work or during exercise

• poor sleep, stress or insufficient recovery

The long sitting period adds an unfamiliar or sustained load, and symptoms finally appear. The pain may feel sudden even though the factors that made the back more sensitive developed gradually.

Posture Matters—but It Is Not the Whole Explanation

It is tempting to blame chronic pain entirely on “bad posture” or a postural imbalance. The relationship is not that simple. Research has not established one spinal posture as the universal cause of low back pain, and there is no single perfect posture that everyone must maintain.

Posture may still be relevant for a particular person—especially when one position is held for too long—but movement variety and the body’s capacity to handle a position are often more important than trying to sit perfectly all day.

Why a Proper Assessment Looks Beyond the Painful Area

If we focus only on the event that triggered the pain, we may calm the current flare without understanding why the back became vulnerable to it.

A more complete assessment may consider:

• which movements and positions worsen or ease the symptoms

• mobility of the spine, hips and surrounding joints

• strength, endurance and movement control

• daily sitting, driving, work and exercise habits

• previous injuries or recurring pain episodes

• sleep, stress and recovery

The goal is not to search for one hidden defect. It is to identify the factors that are most relevant to that individual and build a plan that improves comfort, function and confidence.

Building Capacity, Not Just Chasing Symptoms

Relieving pain is important, but lasting progress often requires more than treating the sore area. Recovery may include gradually returning to activity, changing positions more often, improving relevant mobility and strength, and progressively increasing the body’s tolerance for work, travel and exercise.

At DUR1 Health in North York, we look beyond where the pain is felt. Our approach considers movement, strength, mobility, daily demands and recovery so that care can be matched to the individual—not only to the latest flare-up.

When to Seek Prompt Medical Care

Low back pain after a major accident, or pain accompanied by new bowel or bladder changes, numbness around the groin or saddle area, progressive leg weakness, fever, unexplained weight loss or other unusual symptoms, should be assessed promptly by an appropriate medical professional.
