Quick answer (60 sec read) Around 90% of low back pain is non-specific — there isn't a single structural cause that explains the pain. Most acute episodes improve within 4–6 weeks with movement, manual therapy, and graded activity. Imaging usually isn't needed unless red flags are present, and bed rest is consistently associated with worse outcomes than gentle movement.

Low back pain — assessment and management

Low back pain is one of the most common reasons people see a musculoskeletal practitioner — and one of the most over-investigated and over-medicalised. Most low back pain is non-specific and improves over weeks with movement, manual therapy, and graded activity (Maher, Underwood & Buchbinder, *Non-specific low back pain*, Lancet 2017). Max's role is to identify what fits the picture, recognise the small proportion that needs onward investigation, and build a plan that gets you confidently moving again.

What's usually behind low back pain

The vast majority — around 90% — of low back pain is non-specific: there isn't a single structural cause that explains the pain. That can feel unsatisfying, but it's actually reassuring — non-specific low back pain generally improves with time, movement, and a sensible plan.

Less commonly, low back pain has an identifiable cause:

Radicular pain — referring down the leg in a nerve-root pattern (often called sciatica — see below)
Stenosis-pattern pain — leg symptoms with walking, easing with sitting or bending forward
Inflammatory back pain — younger patients, morning stiffness over an hour, improves with movement (worth GP or rheumatology input)
Serious causes (rare) — fracture, infection, malignancy, cauda equina syndrome

Part of an initial assessment is sorting which pattern fits.

Sciatica — when back pain refers down the leg

"Sciatica" is the common name for radicular pain — leg pain in a nerve-root distribution, usually from irritation or compression of a lumbar nerve root. It typically runs from the buttock down the back or side of the leg, sometimes below the knee into the calf or foot, and may come with pins and needles or numbness in the same distribution. The leg pain is often worse than the back pain.

Three things worth knowing:

Most sciatica improves without surgery. The natural course over weeks to months is generally favourable; management mirrors non-specific low back pain — staying active in tolerable amounts, graded exercise, and manual therapy as an adjunct, with progress reviewed.
It needs monitoring, not panic. Persistent or progressively worsening leg weakness, numbness, or pins and needles warrant GP review and possibly imaging — Max screens for this at each visit and refers when the pattern calls for it.
One presentation is an emergency: new loss of bladder or bowel control, numbness in the saddle region, or rapidly progressive leg weakness can indicate cauda equina syndrome — call 000 or go straight to an emergency department.

If your leg symptoms fit a sciatica pattern, the assessment and management below still apply — the examination just adds careful neurological screening of the lower limb.

How it typically presents

Pain in the lumbar or lumbosacral region
May be central, one-sided, or refer to the buttock or upper thigh
Onset can be sudden (after a specific movement) or gradual
Behaviour varies — some people are worse with sitting, others with standing or walking
May come with stiffness, particularly first thing in the morning
Mood, sleep, and stress often interact with the pain experience — this isn't psychological in the dismissive sense; it's how human pain works

How Max assesses low back pain

An initial assessment includes:

History — onset, behaviour through the day, sleep, activity tolerance, and any leg symptoms
Examination — range of motion, palpation, neurological screening of the lower limb (sensation, strength, reflexes), and movement assessment (gait, sit-to-stand, hip and pelvic mechanics)
Red-flag screening — checking for the small number of cases that need urgent or onward referral
Differential consideration — mechanical low back pain, radicular pain (sciatica), stenosis pattern, hip-related pain, sacroiliac involvement, inflammatory features

How osteopathy may help — the management approach

Management for non-specific low back pain typically combines:

Education and reassurance — most acute low back pain improves; the pain experience isn't a direct measure of damage; movement is generally safer than rest
Manual osteopathic therapy — manual techniques targeting the lumbar, pelvic, and hip regions; see how Max works
Graded exercise — early gentle movement, progressing to strength, mobility, and load tolerance over weeks
Activity modification (not bed rest) — staying active in a tolerable way is consistently associated with better outcomes than rest
Sleep and contributing factors — these are part of the picture, particularly for persistent presentations
Onward referral or imaging — when red flags, persistent radicular symptoms, or features suggesting a different diagnosis are present

What a course of care typically looks like

Most acute, non-specific low back pain improves within 4–6 weeks. Initial appointments are typically weekly while symptoms are active, then taper.

Persistent low back pain — present for 3 months or more, or recurring frequently — usually takes longer and benefits from a broader plan that includes strength, activity, and sleep factors as well as hands-on care.

When to see your GP or A&E instead

Call 000 or go to an emergency department immediately if you experience any of the following — these are signs of cauda equina syndrome or serious spinal pathology:

Loss of bladder or bowel control (new incontinence, retention, or saddle numbness around the perineum)
Sudden, severe weakness in one or both legs
Significant trauma (major fall, motor vehicle accident) with new back pain

Contact your GP if you have:

Progressive neurological symptoms (worsening leg weakness, numbness, or pins and needles)
Fever, unexplained weight loss, or night pain not related to the day's activity
History of cancer with new back pain
Severe pain that isn't improving after a few weeks despite a sensible plan

These warrant medical assessment before, or alongside, osteopathic care.

Frequently asked

Q. Do I need a scan for my back pain? Usually not. For non-specific low back pain, imaging often doesn't change management and can sometimes increase concern by revealing common, age-related findings that aren't causing the pain (for example, mild disc bulges or osteophytes that most adults have). Imaging is appropriate when there are red flags, persistent neurological symptoms, or when the picture doesn't fit.

Q. Should I rest or move? Move — gently, in tolerable amounts. Prolonged rest is consistently associated with worse outcomes. Even when pain is significant, gentle movement (walking, light mobility) is safer and more effective than bed rest.

Q. Will my back pain become chronic? Most acute low back pain doesn't. Around 80% of episodes improve within a few weeks. The presentations more likely to persist are those with high pain intensity early on, low expectations of recovery, sleep disruption, and ongoing significant activity restriction. Early sensible care and staying active are protective.
