Back pain is one of the most common health complaints in daily life — particularly lower back pain. Many people accept it as a normal consequence of ageing or physical work. While back pain typically resolves within a few weeks, in some cases it persists beyond 12 weeks. When it does, it is classified as chronic back pain — a signal that the body requires more than basic rest and self-care.
Chronic back pain is not simply a physical problem. Left inadequately treated, it can affect mental health, reduce quality of life, and lead to significantly higher healthcare costs over time.
What Causes Chronic Back Pain?
Chronic back pain can arise from multiple overlapping factors — structural degeneration, disc problems, lifestyle habits, and psychological influences. The main categories are as follows.
- Spinal Degeneration
- Degenerative disc disease the intervertebral discs that cushion the vertebrae lose their height and elasticity over time; as the discs thin, vertebrae may rub against each other, producing persistent pain
- Spinal stenosis narrowing of the spinal canal compresses the spinal cord and nerve roots, causing pain, numbness, and weakness, often radiating into the legs
- Facet joint osteoarthritis inflammation and degeneration of the small joints at the back of each vertebra cause localised pain and restricted movement
- Structural and Disc Abnormalities
- Herniated or bulging disc — disc material protrudes and presses on surrounding nerve roots, causing back pain that often radiates down the leg (sciatica)
- Spondylolisthesis — one vertebra slips forward over the one below it, creating spinal instability and pain
- Scoliosis or spinal deformity — abnormal curvature of the spine alters the distribution of load and pressure across vertebral structures, generating chronic mechanical pain
- Behavioural and Physical Factors
- Poor posture and movement habits prolonged slouching at a desk, forward head posture, or incorrect lifting technique places chronic mechanical stress on spinal structures; a common driver in office workers
- Weak or deconditioned muscles insufficient physical activity weakens the muscles that support the spine, transferring more load onto the bones, discs, and joints
- Excess body weight additional weight increases mechanical pressure on the spine and joints at every level
- Injury and Medical Conditions
- Chronic muscle and ligament strain — repetitive overuse or inadequately rehabilitated injuries leave muscles and ligaments persistently inflamed or weakened
- Osteoporosis — reduced bone density increases the risk of vertebral compression fractures, which can produce severe, long-lasting pain
- Infection or spinal tumour Infection or spinal tumour — uncommon but important causes of persistent back pain that do not respond to standard treatment and require specific investigation
- Psychosocial Factors
Stress, anxiety, and depression are well-established contributors to chronic back pain. Psychological distress causes persistent muscle tension and lowers pain tolerance — both of which can transform episodic back pain into a chronic condition, or significantly worsen pain that is already present.
Common Symptoms
- Persistent pain a constant dull ache, deep aching, or burning sensation in the back lasting for months without a clear period of relief
- Radiating pain pain that travels from the lower back into the hip, buttock, or down the leg; often associated with nerve compression such as sciatica
- Reduced range of motion stiffness and tightness that make bending forward, twisting, or rotating the torso difficult or painful
- Numbness or tingling sensations in the leg or foot that suggest nerve root involvement
- Posture- or activity-dependent pain pain that worsens after prolonged sitting or standing, or with specific activities such as lifting
- Muscle spasms or contractions involuntary tightening or cramping of the muscles surrounding the spine, causing sharp pain and further limiting movement
Treatment Options
The primary approach to chronic back pain isnon-surgical, with the goal of reducing pain, restoring physical function, and returning the patient to a good quality of daily life. Surgery is considered only in specific cases where conservative treatment has failed or where there is a clear surgical indication.
- Physiotherapy and exercise Physiotherapy focuses on strengthening the core stabilising muscles of the trunk — the deep abdominal and back extensors — to provide better mechanical support for the spine. Improving flexibility, movement quality, and body mechanics is equally important for long-term recovery and relapse prevention.
- Medication — Analgesics and non-steroidal anti-inflammatory drugs (NSAIDs) help reduce pain and inflammation. Other adjuvant medications may be prescribed depending on the nature of the pain — including neuropathic agents or muscle relaxants where indicated. All medication should be used under physician supervision.
- Interventional Procedures When initial conservative treatment is insufficient, targeted non-surgical procedures offer effective pain relief:
- Epidural steroid injection anti-inflammatory medication is delivered into the epidural space surrounding the spinal cord, reducing nerve root inflammation and providing meaningful relief from radiating leg pain
- Nerve block injection anaesthetic delivered precisely to the nerve or nerve group responsible for transmitting pain signals, interrupting the pain pathway
- Radiofrequency ablation (thermal neurotomy) a radiofrequency probe uses targeted heat to deactivate the small nerve branches transmitting pain from degenerated facet joints; provides durable, long-lasting relief without surgery
- Complementary Therapies Yoga, acupuncture, and therapeutic massage can contribute meaningfully to pain reduction and improved physical function as adjuncts to medical treatment, when practised under appropriate professional guidance.
- Psychological Support Because chronic pain and psychological distress are closely linked, Cognitive Behavioural Therapy (CBT) and psychological counselling can meaningfully improve a patient's ability to cope with persistent pain — and in some cases, reduce its perceived intensity and its impact on daily life.
Prevention
- Strengthening and flexibility
- Core strengthening — targeting the deep abdominal and back extensor muscles — provides the foundational spinal support that reduces injury risk and pain recurrence
- Regular stretching reduces muscle tension and the pulling forces on the lumbar spine that contribute to chronic pain
- Low-impact aerobic exercise such as walking, swimming, or yoga maintains overall spinal health without placing excessive load on the joints - Behavioural and ergonomic adjustments
- Use correct posture and technique when working, sitting, and lifting
- Set up your workstation ergonomically: chair adjusted to support the natural lumbar curve, monitor at eye level
- Take regular movement breaks — stand up and stretch every 30–45 minutes during prolonged desk work to reduce cumulative muscle tension - General health
- Maintain a healthy body weight to reduce mechanical load on the lumbar spine
- Quit smoking — smoking impairs disc nutrition through reduced blood supply and accelerates spinal degeneration
- Eat a nutritionally balanced diet that supports bone density and muscle health
- Manage stress through regular relaxation practices; where needed, seek professional psychological support
