Lower Back Pain: Causes, Symptoms and When Physiotherapy Can Help

Lower back pain is the leading cause of disability worldwide, and the most common musculoskeletal complaint seen in clinics across Bangalore. If your back has been hurting, the most useful thing to know first is this: around 90 percent of acute lower back pain episodes improve substantially within six weeks, and most do not require a scan.

What matters is distinguishing ordinary mechanical back pain, which responds well to movement and physiotherapy, from the small minority of cases that signal something requiring urgent attention.

What Causes Lower Back Pain?

Non-specific mechanical back pain accounts for the large majority of cases. The absence of a precise structural label is not a failure of diagnosis. It reflects that most back pain arises from a combination of muscle, joint, and load factors rather than a single identifiable lesion.

Red Flags: When Back Pain Needs Urgent Assessment

Seek medical attention promptly if back pain is accompanied by any of the following:

• Loss of bladder or bowel control, or difficulty passing urine
• Numbness in the saddle area, meaning the inner thighs, groin, or buttocks
• Progressive weakness in one or both legs
• Fever alongside back pain
• Unexplained weight loss
• A history of cancer
• Significant trauma, or minor trauma in someone with osteoporosis
• Pain that is severe at night and not relieved by position change
• Age of onset under 20 or over 55 with new severe pain

The first three together suggest cauda equina syndrome, which is a surgical emergency. These are uncommon, but they are the reason that dismissing all back pain as routine is unwise.

Do You Need a Scan?

For most people with new back pain and no red flags, the answer is no, and this surprises patients.

Current international guidelines advise against routine imaging in the first six weeks of back pain without red flags. The reason is that scans of symptom-free adults frequently show disc bulges, degenerative changes, and other findings that look alarming but correlate poorly with pain. Imaging early often identifies incidental findings that lead to unnecessary anxiety and intervention without improving outcomes.

X-ray shows bone. It does not show discs or nerves. For suspected disc prolapse or nerve compression, MRI is the correct investigation.

How Physiotherapy Helps Lower Back Pain

Physiotherapy for lower back pain is not simply a set of exercises handed over on a sheet. A proper assessment identifies which movements provoke and which relieve your pain, where strength and control are lacking, and what in your daily loading pattern is maintaining the problem.

Typical components:

Education and reassurance. This sounds minor and is not. Understanding that movement is safe, that hurt does not equal harm in mechanical back pain, and that most episodes settle changes behaviour and measurably improves outcomes.

Graded activity and movement. Prolonged bed rest worsens outcomes for back pain. Staying active within tolerable limits is one of the strongest evidence-based recommendations.

Specific exercise therapy. Core and gluteal strengthening, motor control retraining, and directional preference exercises based on what your assessment shows.

Manual therapy. Mobilisation and soft tissue techniques, used as an adjunct to exercise rather than as standalone treatment.

Ergonomic and load management advice. Particularly relevant for desk workers, covering chair setup, monitor height, and movement breaks.

Exercise Is the Most Evidence-Backed Treatment

Across international guidelines, exercise therapy consistently emerges as the first-line treatment for persistent lower back pain. Not a single specific exercise, but regular, progressive, supervised movement.

What the evidence does not support as standalone treatment: prolonged bed rest, routine early imaging, long-term opioid use, and passive modalities used alone without active exercise.

What You Can Do Starting Today

• Keep moving. Gentle walking within comfort is better than rest
• Avoid prolonged sitting. Stand and move every 30 to 45 minutes
• Apply heat for muscle-dominant pain, which eases guarding and spasm
• Sleep in a comfortable position, with a pillow between the knees if side-lying
• Use simple analgesia as advised by your doctor for short-term relief during an acute episode
• Return to normal activity progressively rather than waiting to be pain-free first

When to See a Doctor or Physiotherapist

Book an assessment if your back pain has lasted more than two weeks without improvement, keeps recurring, radiates into the leg, affects your sleep or work, or if you are unsure whether what you are feeling is ordinary strain.

Seek urgent care for any of the red flags listed above.
