What low back pain is
Low back pain means pain between the bottom of the ribs and the fold of the buttocks, with or without pain referring into the hip or thigh. It is the single most common reason people book an appointment at the clinic, and the most common cause of years lived with disability worldwide.
The large majority of cases are classed as non-specific low back pain. That label sounds unsatisfying, and it is worth understanding what it means: the pain is coming from the structures of the back working together, rather than from one identifiable injury such as a fracture, an infection or a compressed nerve root. Somewhere between 90 and 95 per cent of presentations fall into this group.
Non-specific does not mean minor. It can be severe enough to stop you standing up straight. It means the useful question is what makes it better and worse, rather than which single tissue to blame.
What causes it
Back pain is usually the result of load meeting capacity at a bad moment. Something asked more of the tissue than it was ready for that day: a heavier lift, an unfamiliar movement, a long drive after a week of sitting, or a poor night of sleep before a busy day on your feet.
That is why the same bend to pick up a sock can trigger an episode when a heavy deadlift the week before did not. The load was small, and the capacity that morning was smaller.
What raises the risk
- A sudden change in activity, in either direction. Ramping training up quickly and stopping entirely both count.
- Long periods in one position, particularly seated, without breaks to move.
- Poor sleep. Two or three short nights measurably lowers pain threshold.
- Stress and high workload, which raise muscle guarding and lower tolerance.
- A previous episode of back pain, which is the strongest single predictor of another.
- Deconditioning of the hips, glutes and trunk, which leaves the back doing work it was not built to do alone.
Imaging findings correlate poorly with symptoms. In studies of people with no back pain at all, disc degeneration appears in roughly 37 per cent of 20-year-olds and over 90 per cent of 60-year-olds, with disc bulges in more than half of asymptomatic 50-year-olds. Terms like "degeneration" and "wear and tear" on a report often describe normal age-related change, in the same way that grey hair is normal age-related change. This matters clinically, because people told their spine is crumbling move less, and moving less is what prolongs the episode.
What the evidence says
International guidelines, including NICE in the UK, have converged on the same first-line advice: stay active, continue normal activity as far as pain allows, and use exercise as the primary treatment. Bed rest performs worse than staying mobile on every outcome measured, including pain.
No single form of exercise wins. Pilates, general strength work, walking programmes, yoga and motor-control training all produce broadly similar improvements. The variable that predicts the result is whether the person keeps doing it, which is a strong argument for choosing something you can tolerate and will repeat.
Manual therapy, including joint mobilisation and soft tissue work, has good short-term evidence for pain relief and improved movement. It works best as a way to open a window in which you can move and load more comfortably, with exercise doing the longer-term work.
Routine imaging for non-specific low back pain is recommended against, because it rarely changes management and is associated with worse outcomes. Scans belong with specific clinical suspicions, which is what the red flag list further down is for.
Recovery timeline
Most acute episodes improve substantially within two to six weeks. Recovery is rarely a straight line, and a flare in week three after a good week two is a normal part of the pattern rather than a sign of new damage.
Recurrence is common, with something like half of people having another episode within a year. Building genuine hip and trunk strength over three to six months is the most reliable way to make the next episode shorter and milder.
| Stage | ✓ Do this | ✗ Avoid this |
|---|---|---|
| Days 1–3 | Keep moving in short, frequent bouts. Walk. Change position often. Use heat for comfort. | Bed rest, or waiting until it stops hurting before moving at all |
| Week 1–2 | Return to normal activity as pain allows. Gentle range-of-motion work. Consider a hands-on session to settle guarding. | Bracing all day, or avoiding every movement that produces any sensation |
| Week 2–6 | Progressive loading: hip hinge patterns, glute and trunk strength, graded return to your sport. | Jumping straight back to your heaviest pre-injury loads |
| Beyond 6 weeks | Keep the strength work as maintenance, two sessions a week. Manage sleep and total training load. | Stopping the exercises the week the pain stops |
How we treat it at Kingsway
A typical first session
The first appointment is about working out which movements provoke it, which relieve it, and whether anything on the red flag list needs ruling out before treatment starts.
- Full history and a movement assessment of the spine, hips and lower limb
- Hands-on work to reduce guarding: deep tissue release through the paraspinals, glutes and hip flexors
- Joint mobilisation of the lumbar spine and, where indicated, the thoracic spine and hips
- Trigger point release or dry needling into the muscles reproducing your pain
- Cupping across the lower back where the tension is broad rather than focal
- Two or three specific exercises to take away, with the dose written down
Most people with an acute episode need somewhere between three and six sessions. Longstanding pain, or pain that has already recurred several times, usually needs a longer run of appointments focused on building capacity, which is what the five and ten session packages are priced for.
When to get it checked
Book an assessment if the pain has lasted more than two weeks without clear improvement, if it keeps returning, or if it is limiting work or sport. Get seen sooner if pain is travelling down the leg past the knee, or if there is numbness, pins and needles or weakness in the leg or foot.
See a doctor or go to A&E if
- Loss of bladder or bowel control, or difficulty passing urine
- Numbness around the groin, genitals or inner thighs, sometimes described as saddle numbness
- Progressive weakness in one or both legs, or a foot that catches when you walk
- Back pain after a significant fall or accident, or in anyone with osteoporosis
- Unexplained weight loss, fever, night sweats, or a history of cancer alongside new back pain
- Severe pain that is markedly worse at night and unrelieved by any position
Common questions
Should I get an MRI scan?
For a first episode of back pain with no red flags, the answer is almost always no. Guidelines advise against routine imaging because the findings rarely change what treatment is recommended, and reports full of normal age-related change often make people more fearful of moving.
Scans become useful when there is a specific clinical suspicion: progressive neurological signs, a red flag from the list above, or a case that has failed a proper course of conservative treatment and surgery is being considered.
Is it safe to exercise while my back still hurts?
In the large majority of cases, yes, and it is the treatment. A useful rule is that pain up to about 4 out of 10 during activity is acceptable if it settles within 24 hours and you are not worse the next morning.
What is worth avoiding is the all-or-nothing pattern: complete rest for a fortnight, then a full return to everything at once.
Is my posture the cause?
Posture is a smaller factor than it is usually given credit for. Studies have repeatedly failed to find a consistent link between any particular sitting or standing posture and who develops back pain.
What does matter is how long you hold any one position. The most useful change for most desk workers is a reminder to move every 30 to 40 minutes, rather than a search for the perfect chair.
Does a slipped disc mean surgery?
Rarely. The great majority of disc-related back and leg pain settles with conservative treatment over six to twelve weeks, and disc herniations frequently reduce in size on their own over that period.
Surgery is generally reserved for progressive neurological deficit, cauda equina syndrome, or leg pain that has not responded to a proper course of treatment.
