Recognizing Common Causes of Back Pain: A Clinical Overview

Back pain presents across a spectrum from short-lived, activity-related discomfort to persistent symptoms that limit daily function. Clinicians begin with a focused history and physical examination to separate common mechanical causes from inflammatory, infectious, or neoplastic processes. Patterns such as radicular pain, axial low back pain, or pain with systemic features guide further testing and management planning. Early attention to function and symptom trajectory helps determine whether conservative care, targeted imaging, or specialist referral is appropriate.

What causes back pain?

Common contributors include muscle or ligament strain, degenerative disc changes, herniated discs compressing nerve roots, facet joint arthropathy, and spinal stenosis leading to neurogenic claudication. Less frequent but important causes include inflammatory spondyloarthropathies, vertebral infection, or malignancy. Mechanobiology plays a role: altered biomechanics, repetitive loading, and postural factors can predispose to chronicity. Identifying red-flag symptoms such as unexplained weight loss, fever, progressive weakness, or bowel/bladder dysfunction is essential to prioritize urgent evaluation.

How does imaging guide diagnosis?

Imaging complements the clinical exam when symptoms persist, neurological deficits arise, or surgery is being considered. Plain radiographs assess alignment, fractures, and advanced degenerative change. MRI provides detailed evaluation of discs, nerve roots, and soft tissues and is preferred for suspected radiculopathy or infection. CT is useful for bony detail or when MRI is contraindicated. Clinicians interpret imaging alongside clinical findings, as age-related changes frequently exist without clear correlation to pain.

When are conservative approaches used?

Most acute and many chronic cases respond to conservative management. Core components include physiotherapy, supervised rehabilitation programs, patient education about pain mechanisms, graded exercise, and activity modification. Short courses of analgesics or anti-inflammatory medications can support participation in therapy. Behavioral strategies, sleep hygiene, and pacing also help. Rehabilitation aims to restore strength, flexibility, and motor control while reducing fear-avoidance behaviors to improve long-term function and lower recurrence risk.

When is neurosurgery or orthopedics needed?

Referral to neurosurgery or orthopedics is appropriate when there is progressive or severe neurological deficit, structural instability, or when prolonged conservative care fails to restore acceptable function. Surgical options are pathology-specific and range from minimally invasive decompression to instrumented fusion for instability or deformity. Shared decision-making considers symptom severity, imaging correlates, comorbidities, and realistic functional goals. Multidisciplinary evaluation often yields the most consistent alignment of treatment and expected outcomes.

How do ergonomics and biomechanics help?

Ergonomics and biomechanical assessment reduce load-related triggers and support rehabilitation goals. Workplace adjustments, proper lifting techniques, and optimizing sitting and standing postures can lower strain on the lumbar spine. Physiotherapists and occupational therapists assess movement patterns and prescribe corrective exercises to address deficits in core stability, hip mobility, and motor control. Integrating ergonomic improvements with home and work routines helps maintain gains achieved through rehabilitation and decreases the chance of recurrence.

What are orthobiologics and intervention options?

Image-guided interventions can provide diagnostic clarity and symptom relief for selected presentations. Epidural steroid injections, facet joint injections, and selective nerve root blocks are commonly used for radicular or facet-mediated pain to reduce inflammation and facilitate participation in rehabilitation. Orthobiologics—such as platelet-rich plasma or cell-based therapies—are under investigation for degenerative disc disease and other degenerative conditions; evidence remains evolving and should be considered within clinical research or carefully selected clinical contexts. Decisions about interventions should be individualized and made with multidisciplinary input.

Conclusion A systematic clinical approach that integrates history, focused examination, and selective imaging helps identify common causes of back pain and direct appropriate treatment. Most cases benefit from conservative care including physiotherapy and rehabilitation, while targeted interventions or referral to neurosurgery or orthopedics are reserved for specific indications. Emphasizing ergonomics, biomechanics, and individualized care plans supports recovery and reduces the risk of recurrent symptoms.
