When Should You See a Physiotherapist for Back Pain?

Most back pain gets better. So when is it worth getting assessed?

Back pain is one of the most common reasons people seek healthcare — and one of the most misunderstood.

If your back hurts, you have probably heard conflicting advice. Rest it. Don't rest it. Get a scan. Don't bother with a scan. Stretch more. Strengthen more. Wait it out.

Here is a more useful way to think about it.

Most episodes of back pain improve within a few weeks, often without any specific treatment. The body is generally very good at settling these episodes on its own. This is genuinely reassuring, and it is the reason healthcare professionals do not rush to intervene in every case.

But "most" is not "all" — and waiting is not always the right answer.

This article covers three things: when it is reasonable to wait, when a physiotherapy assessment is likely to help, and the specific warning signs that mean you should seek medical care promptly rather than waiting at all.

When it is reasonable to give it time

You can usually take a measured approach if:

• The pain came on after an obvious, ordinary trigger — an awkward lift, an unusual amount of activity, a long flight, a heavy training session
• It is uncomfortable but you can still move, walk and manage your day
• It is gradually improving, even slowly
• You have no numbness, weakness or symptoms travelling down your leg
• You are otherwise well

In this situation, the most useful things you can do are often the simplest:

Keep moving. Prolonged bed rest is no longer recommended for ordinary back pain. Gentle, regular movement within your comfort is usually better than complete rest.

Continue your normal activities where you reasonably can, adjusting rather than stopping entirely.

Avoid catastrophising the pain. Back pain is frightening, but pain intensity alone is a poor indicator of how serious the underlying problem is. Severe pain does not automatically mean severe damage.

When a physiotherapy assessment is worth booking

Consider an assessment if any of the following apply:

It is not improving after two to three weeks.

A single painful episode that is settling is one thing. Pain that has plateaued, or that is not following a clear improving trend, is worth having someone look at properly.

It keeps coming back.

Recurring episodes often point to something that has not been addressed — how you move, how much load you can tolerate, strength, mobility, or how a previous episode was managed. Treating each episode in isolation tends to produce the same result each time.

It is limiting things that matter to you.

If you are avoiding exercise, sleeping badly, struggling through your working day, or no longer confident lifting your child or your bag, that is a reasonable trigger regardless of how long it has lasted.

You are not sure what is going on.

Uncertainty is itself a good reason to be assessed. Understanding what is likely happening — and what is not — often reduces anxiety substantially, and anxiety about back pain can genuinely make the experience worse.

You want to know how to prevent the next one.

This is one of the most useful reasons to be assessed, and one of the least common. Assessment after an episode has settled can identify what may have contributed and what could reduce the chance of recurrence.

⚠️ Warning signs that need prompt medical attention

Some symptoms should not be managed with a "wait and see" approach. Seek medical care promptly — do not wait for a physiotherapy appointment — if you experience:

• Numbness in the saddle area — the inner thighs, buttocks or genital region
• New difficulty controlling your bladder or bowels, or loss of sensation when passing urine
• Progressive weakness in one or both legs — for example, a foot that drags or gives way
• Back pain following significant trauma — a fall from height, a road traffic accident
• Back pain with fever, unexplained weight loss, or feeling generally unwell
• Severe pain that is constant, unrelenting and notably worse at night
• Back pain with a history of cancer, a significantly weakened immune system, or long-term corticosteroid use

These signs are uncommon. Most people with back pain will never experience them. But they can indicate conditions that need urgent assessment, and recognising them early matters.

If in doubt, ask. No healthcare professional will consider it a waste of time to check.

What actually happens at a physiotherapy assessment

Many people delay being assessed simply because they do not know what to expect.

We listen first. What are you experiencing? When did it start? What makes it better or worse? How is it affecting your work, sleep, exercise and daily life?

We assess how you move — not only the area where you feel pain. Strength, mobility, movement patterns and relevant physical function all form part of the picture. Sometimes the source of a problem is not where the symptom appears.

We ask what you want to get back to. Returning to running, sitting through a working day, sleeping without discomfort, or lifting your child comfortably are all legitimate goals — and they shape the plan.

We explain what we find in language you can understand, including what we are confident about and what remains uncertain.

We agree a plan together. That may include manual therapy, progressive exercise, mobility work, shockwave therapy where indicated, or other appropriate rehabilitation.

Sometimes the most appropriate recommendation is exercise, a change in activity, or simply reassurance and a sensible plan. At IDUNN, if that is what will help you most, that is what we will say.

What about scans?

This is one of the most common questions — and one of the most misunderstood.

For ordinary back pain without warning signs, imaging is often not the useful first step that people expect it to be.

The reason is that scans frequently show changes in people who have no pain at all. Disc changes and other findings become more common with age and are often part of normal ageing rather than the cause of a specific episode of pain.

This means a scan can sometimes create worry about a finding that was never the problem — and that worry can itself affect recovery.

Imaging is genuinely valuable when there is a specific clinical reason for it: warning signs, suspected serious pathology, symptoms not responding as expected, or when a surgical opinion is being considered.

That is a clinical judgement, made after assessment — not a default first step.

This reflects how we approach care more broadly at IDUNN: understand what is actually needed, use what adds value, and avoid what does not.

The short version

• Most back pain improves within weeks. Staying gently active usually helps more than resting completely.
• Book an assessment if it is not improving after two to three weeks, keeps returning, is limiting things that matter to you, or you simply want to understand it.
• Seek prompt medical care for the warning signs listed above — do not wait.
• Scans are useful when there is a clinical reason for them, not as an automatic first step.
• You do not need a diagnosis before booking. Working out what is going on is the point of the assessment.
