Lower Back Pain: Common Causes, Self-Care, and When to See a Physiotherapist
Most lower back pain is not caused by serious damage, and most of it settles. Here is what tends to cause it, what helps early on, and the signs worth taking seriously.
Lower back pain is one of the most common reasons people see a physiotherapist, and one of the most misunderstood. The reassuring part, which often gets lost, is that the large majority of back pain is not caused by serious structural damage, and most episodes settle over a period of weeks.
That does not make it trivial. Back pain can be genuinely disabling while it lasts, and how you handle the first days influences how the following weeks feel. This article explains what usually drives it, what tends to help, and the specific signs that mean you should be assessed rather than waiting.
What usually causes it
In most cases no single dramatic event is responsible. Lower back pain more often builds from an accumulation: long periods of sitting, a sudden increase in physical work, poor sleep, an awkward lift, or a stressful stretch of weeks. The back is then sensitised, and a movement that would normally be unremarkable becomes painful.
The most common contributors seen in clinic include:
- Muscular strain, often after lifting, twisting or an unusual amount of activity
- Stiffness and deconditioning from prolonged sitting, particularly desk work and driving
- Disc-related irritation, which can refer pain into the buttock or leg
- Joint irritation in the lower spine or sacroiliac region
- Load that increased faster than the body adapted, common in DIY, gardening and gym returns
What the scans do and do not tell you
Imaging findings such as disc bulges and degenerative changes are extremely common in people with no pain at all, and they become more common with age in the same way grey hair does. A scan finding is therefore not automatically the explanation for the pain.
This matters practically. People who believe their spine is damaged tend to move less and guard more, and reduced movement often prolongs the problem. A physiotherapist assesses how you actually move and what provokes and eases your symptoms, and reads any imaging in that context rather than in isolation.
What generally helps in the first days
Current evidence has moved firmly away from bed rest. Staying gently active is usually better tolerated than resting completely, even when movement is uncomfortable at first.
Approaches that commonly help early on:
- Keep moving within comfort. Short, frequent walks are usually better than one long effort
- Change position often rather than holding any one position for long stretches
- Use heat for muscular tightness and stiffness; some people prefer cold in the first day or two
- Continue normal activity where you reasonably can, reducing intensity rather than stopping
- Sleep matters. Pain often feels worse after a poor night, which is physiological, not imagination
Where physiotherapy fits
A physiotherapy assessment aims to work out which movements and structures are involved, whether anything needs onward referral, and what will help you move more comfortably. Treatment is typically a combination of hands-on work, guided exercise, and advice about load and activity.
Exercise is usually the part that carries the lasting change. Passive treatments can ease symptoms and make movement more tolerable, but restoring strength, mobility and confidence in the back is what tends to reduce recurrence.
A realistic timeline
Acute episodes of simple lower back pain often improve substantially within two to six weeks, with the sharpest change usually in the first week or two. Recovery is rarely a straight line, and a flare-up during that period does not mean you are back at the start.
Where pain has been present for more than three months, timelines are longer and the emphasis shifts toward graded strengthening, activity pacing and confidence in movement. Progress in that situation is measured over months rather than days, and it is normal for it to be uneven.
Timelines are general ranges and vary between individuals.
When to see a physiotherapist, and when to seek urgent care
Most back pain does not need imaging or specialist referral. Some presentations do need prompt attention.
- Pain that is not improving at all after two to three weeks of sensible self-care
- Pain that travels below the knee, or is accompanied by numbness, pins and needles or weakness in the leg
- Repeated episodes that keep returning, which usually indicates an unaddressed contributing factor
- Back pain following a significant fall or accident
- Seek urgent medical care, not physiotherapy, for loss of bladder or bowel control, numbness around the groin or inner thighs, or progressive weakness in both legs
- Also seek medical assessment for back pain with unexplained weight loss, fever, or a history of cancer
