How to Ease Lower Back Pain: A Physiotherapist's Guide

What “lower back pain” actually means

Lower back pain is one of the most common reasons people seek help, and most adults have it at some point, so it is not a sign that something is seriously wrong with you. In most cases it is non-specific, which simply means no single structure can be pinpointed as the cause. That can feel unsatisfying when the pain is real and limiting, but it is actually reassuring: non-specific back pain has a strong track record of recovering well.

Sciatica is a little different. It describes pain, tingling or numbness that travels down the leg along the path of the sciatic nerve, usually from irritation of a nerve root in the lower back. It can be more stubborn than a simple backache, but the majority of cases still settle without surgery.

Keep moving: why rest usually makes it worse

The old advice to lie flat until the pain passes has been overturned by the evidence. NICE guideline NG59 (low back pain and sciatica in over-16s) recommends exercise, manual therapy and education as first-line care, and specifically advises against prolonged bed rest, which slows recovery and raises the risk of the problem dragging on.

Stay as active as your pain reasonably allows. Walking, gentle movement and keeping to your normal routine (work, chores, light activity) are recommended even during an acute flare. You may need to modify how you do certain things for a while, but the aim is to keep moving, not to freeze.

What you can do in the first few days

Most flares settle over a few weeks. In the meantime, a few sensible steps help:

• Keep moving little and often. Short, frequent walks and changing position regularly beat long spells sitting or lying down.
• Modify, don’t stop. Reduce the load on tasks that spike your pain rather than avoiding activity altogether.
• Use heat for comfort. Heat can ease muscle guarding and make movement easier; it will not fix the cause, but comfort helps you stay active.
• Protect sleep and manage stress. Poor sleep, high stress and low mood are well-evidenced amplifiers of pain, so they are worth looking after.

If simple measures are not turning things around within a week or two, that is the point to get it looked at properly.

Red flags: when back pain needs urgent care

Serious causes of back pain are rare, but a few symptoms need urgent medical attention rather than physiotherapy. Go to A&E immediately if you develop:

• Loss of bladder or bowel control
• Numbness around the saddle or genital area
• Progressive weakness in both legs

These can signal cauda equina syndrome, a rare emergency that needs urgent assessment within hours. You should also seek urgent care after significant trauma, such as a fall or accident. If you have none of these, your back pain is very unlikely to be dangerous, but if you are unsure, get it checked.

Do you need a scan?

Usually not. NICE advises against routine imaging for non-specific low back pain and sciatica, because a scan rarely changes what the treatment will be and frequently shows incidental findings (disc bulges, mild wear and tear) that are just as common in people with no pain at all. Seeing those on a report can make pain feel more threatening than it really is.

Imaging does have its place: genuine red flags, or symptoms that fail to improve and point to a specific cause, are reasons to investigate further. For everyday back pain, though, a careful physical assessment usually tells us far more than a picture does.

How physiotherapy treats persistent or recurring back pain

If your pain is severe, keeps coming back, or has not settled on its own, physiotherapy is the first-line approach. At Kaizen it starts with a proper assessment: a detailed history and an examination of how your back and the surrounding areas move, so we can agree a working diagnosis you understand before any treatment begins.

From there, treatment combines hands-on manual therapy with a progressive, individualised exercise plan: the combination NICE recommends. Exercise rehabilitation is the strongest evidence-based defence against recurrence, because it rebuilds the strength and load tolerance the lower back needs for daily life, work and sport. Where it helps, we offer physiotherapy-led Reformer Pilates as an exercise-based way to build controlled trunk and lower-limb strength, in line with the NG59 emphasis on exercise. The goal is not to keep you coming back indefinitely; it is to give you the tools and confidence to manage independently.

When to book an assessment

Book an assessment if your back pain is severe, is not improving after a week or two, keeps returning, or is getting in the way of work, sleep or the things you enjoy. UK physiotherapists are first-contact practitioners, so you can self-refer and book directly; no GP letter needed. We look after everyone from desk-bound City professionals managing recurring flares to runners and athletes returning to sport, across our five London clinics or online.

An honest assessment, a diagnosis in plain terms, and a plan built around your goals is the fastest route back to moving well, and staying that way.
