Back Pain Series - Topic 1 - Understanding Lower Back Pain & Spinal Pain – Why Your Scan Doesn’t Always Tell the Full Story


Lower back pain and spinal pain are incredibly common. In fact, according to guidance from National Institute for Health and Care Excellence, around 60–80% of adults will experience lower back pain at some point in their lives.

For many people, back pain can feel worrying — especially when it’s severe, recurring, or affecting sleep, work, exercise, or daily life. One of the first questions people ask is:

“Should I have a scan?”

The answer is often not necessarily.

What actually causes lower back pain?

The spine is made up of many different structures, including:

  • Muscles

  • Joints

  • Ligaments

  • Intervertebral discs

  • Nerves

  • Fascia and connective tissues

Any of these structures can become irritated or sensitised and contribute to pain.

Sometimes lower back pain starts after:

  • Lifting or bending

  • A sporting injury

  • Gardening or DIY

  • Stress or lack of sleep

  • Long periods of sitting

  • Doing “too much too soon”

And sometimes there’s no obvious trigger at all.

Why scans don’t always explain pain

Many patients that attend our physio clinics are surprised to learn that MRI scans often show “changes” in people who have absolutely no pain.

Research has shown that disc bulges, degeneration, arthritis, and “wear and tear” are commonly seen in pain-free adults. These changes are often just normal age-related findings — much like getting wrinkles or grey hair.

By the age of 30, many people already have some spinal changes visible on imaging, even when they feel completely fine.

Scan results.

This is why scans are generally used to:

  • Rule out serious pathology

  • Investigate significant nerve symptoms

  • Help guide surgical planning if required

In the absence of neurological deficits such as:

  • Significant weakness

  • Loss of bladder or bowel control

  • Progressive numbness

  • Severe nerve compression

…surgery is rarely indicated for lower back pain.

Hurt does not always equal harm

One of the most important messages in modern spinal pain treatment is:

Pain does not always mean damage.

Backs are strong, adaptable, and designed for movement.

Pain can sometimes persist because tissues have become sensitive — not because the spine is “out of place,” “damaged,” or “crumbling.”

Understanding this can be incredibly reassuring and is often a key part of recovery.
