Low back pain, lumbago and chronic pain: what do they mean?
Low back pain is pain between the lowest ribs and the buttocks. It tells you where the pain is, rather than exactly which tissue causes it. Lumbago is commonly used for a recent episode, sometimes with severe pain and a feeling that the back has locked. That sensation does not prove that a vertebra has moved out of place.
The term non-specific low back pain is used when assessment does not identify a particular disease or structural cause that needs specific treatment. Your pain is real even when no single muscle or disc can explain every sensation. Pain lasting more than three months is described as chronic. This describes its duration, not an inability to improve.
Understand the picture
The lower back works as a whole
Vertebrae
These bones form the spine and help protect nerve structures.
Discs
Between the vertebral bodies, discs help distribute load and allow movement.
Muscles
Muscles around the spine produce and control movement. A painful spot does not identify a damaged tissue on its own.
What might it feel like?
You may notice an ache, tightness, pain on one side or a sharp pain when standing up. Muscles can tighten around the painful area and some movements become difficult. Symptoms can change during the day. Pain intensity alone does not tell you how much tissue damage, if any, is present.
Pain in the back or buttock does not by itself establish sciatica. Pain travelling down the leg, especially with tingling, altered sensation or weakness, needs a different assessment. Describe these changes clearly. The location and development of symptoms are more useful to a clinician than a diagnosis chosen from an online picture.
Why can the back become painful?
The vertebrae, discs, joints, muscles and nerves work together. An unfamiliar task or an increase in physical demands can precede an episode, but often there is no clear trigger. It is not always possible to identify a single responsible structure.
Sleep, stress, general health, work demands and previous experiences also influence pain and recovery. This does not make the pain imaginary. For example, poor sleep combined with demanding days can make an ordinary task harder to tolerate. Assessment looks for factors you can change, rather than assuming you have one posture fault that must constantly be corrected.
What happens in an assessment, and do you need an MRI?
The doctor asks when symptoms began, where they spread, what changes them and how they affect daily life. They also check for injury, illness, fever and possible nerve symptoms. Depending on the situation, examination may include movement, strength, sensation and reflexes.
An X-ray or MRI is not usually needed at the start of a recent episode without warning signs. Disc changes also occur in people without pain, so a scan does not always provide the explanation you expect. Imaging can help when a particular cause is suspected or its result could change care. Persistent or changing symptoms call for reassessment, rather than the same scan for everyone.
When should you seek advice before exercising?
New difficulty passing urine, loss of bladder or bowel control, loss of feeling around the genitals or severe, worsening weakness in both legs requires immediate help. Call 112 in Luxembourg. You do not need to wait for all these symptoms to occur.
Fever, feeling generally unwell, rapidly worsening pain or new weakness in one leg needs prompt medical advice. Mention a history of cancer, unexplained weight loss, trauma or osteoporosis. A single warning feature does not prove serious disease, but it can change the assessment needed. Also seek help if pain prevents ordinary activities or is not starting to improve.
How can physiotherapy help?
Following assessment and within your prescription, care may combine explanations, suitable movement and a gradual return to useful activities. A goal might be standing up more easily, walking to the shops or resuming a work task. These goals make progress visible beyond a pain score.
Your physiotherapist helps you find a manageable starting level and adjust it. Hands-on treatment may support exercise when helpful; it does not replace active participation. Fear of movement, sleep problems and work pressures also deserve discussion when they prevent progress. Coordination with your doctor or other professionals may be useful.
Medicines and other treatments: what is their role?
Pain relief may help you sleep or move through a difficult period. It does not mechanically put the back into place. The choice depends on other health conditions, medicines and possible side effects. Ask your doctor or pharmacist what is suitable and how long to use it.
Anti-inflammatory medicines are unsuitable for some people, including those with certain stomach, kidney or cardiovascular problems. Do not increase doses or combine products without advice. Surgery is not a usual step for non-specific low back pain. If difficulties continue despite appropriate care, the treatment plan should be reviewed with you.

What can you do day to day?
Keep ordinary activities that remain manageable. Brief rest in a comfortable position may help, but spending days in bed can make returning to activity harder. Alternate walking, sitting and small tasks rather than trying to hold a perfect posture all day.
Break difficult tasks into smaller parts. If standing to prepare a whole meal is too much, alternate seated and standing preparation or pause before symptoms become much worse. At work, discuss temporary changes to load, task duration and available support. The aim is progress that fits your response, rather than completing everything despite a lasting increase in symptoms.
In everyday life
Measure progress in your own day
Choose
Identify an activity you would like to regain.
Adjust
Temporarily reduce its duration or load to find a manageable starting point.
Review
Observe your response, then build gradually. Seek reassessment if your condition worsens.
Exercises: find an appropriate starting point
There is no essential exercise for every person with low back pain. A programme may combine mobility, strength and endurance activity such as walking, according to your abilities. Each movement should have an understandable purpose and an amount you can repeat without a major flare.
Our exercise page explains three simple movements, their starting positions, initial amounts and stopping signs. They are examples to discuss, not a universal programme. Ask first about suitability after recent surgery, with a known spinal condition or with leg symptoms. Stop and seek advice for significant new pain, weakness, loss of sensation or spreading symptoms.
How long does recovery take?
Many recent episodes improve over several weeks. Progress is not always smooth: a more painful day does not automatically mean new damage. Notice activities you can do again, sleep and how easily you resume activity after a break.
Arrange a review if improvement is not emerging; French guidance suggests reassessment two to four weeks after a flare. Do not wait for that interval if a warning sign appears. Beyond three months, a broader approach may help: progressive activity, sleep support, pain management and social or work adjustments. Persistent pain deserves care without concluding that your back is permanently fragile.
Your questions
Does severe pain mean serious damage?
Not necessarily. Non-specific low back pain can be very painful. However, sudden unusual pain, rapid deterioration or warning signs needs assessment. Intensity alone can neither confirm nor rule out a serious cause.
Must I be pain-free before returning to work?
Not always. An adapted return may be possible before pain disappears. It depends on your tasks, health and available adjustments. Discuss this with your doctor and, when relevant, occupational health.
Can stress really affect my back?
Yes. It can influence sleep, muscle tension, pain sensitivity and how you manage activity. That does not make pain imaginary. Emotional circumstances are considered alongside physical and medical factors.
