Low back pain is one of the most common musculoskeletal conditions, affecting people of all ages. It can range from mild discomfort to severe pain that interferes with daily activities such as sitting, standing, walking, or lifting. In most cases, low back pain improves with simple measures, but some individuals may experience persistent or recurrent symptoms.

What Is Low Back Pain?
Low back pain refers to pain, stiffness, or discomfort felt in the lower portion of the spine, between the rib cage and the hips. The pain may develop suddenly or gradually and can vary in intensity. It is commonly related to mechanical factors such as posture, movement, or muscle strain, but it may also be associated with underlying medical or degenerative conditions.
Symptoms of Low Back Pain
Common Symptoms
- Dull or aching pain in the lower back
- Stiffness, especially after rest or prolonged sitting
- Reduced flexibility or difficulty bending
- Pain that worsens with movement or prolonged standing
Less Common Symptoms
- Sharp or shooting pain
- Pain radiating to the buttocks or thighs
- Muscle tightness or spasms
Emergency Warning Signs
Seek immediate medical attention if low back pain is associated with:
- Loss of bladder or bowel control
- Progressive weakness in the legs
- Numbness in the groin or saddle area
- Severe pain following trauma or an accident
- Fever, unexplained weight loss, or persistent night pain
Causes of Low Back Pain
Low back pain can occur due to a combination of mechanical, lifestyle-related, and medical factors.
Mechanical Causes
- Muscle or ligament strain
- Poor posture
- Sudden or repetitive movements
- Improper lifting techniques
Lifestyle-Related Causes
- Prolonged sitting
- Physical inactivity
- Weak trunk and core muscles
- Excess body weight
Medical Causes
- Degenerative disc changes
- Disc herniation
- Spinal osteoarthritis
- Spinal stenosis
- Inflammatory spinal disorders (less common)
Risk Factors
Factors that increase the likelihood of developing low back pain include:
- Increasing age
- Sedentary lifestyle
- Occupations involving prolonged sitting or heavy lifting
- Obesity
- Smoking
- Poor physical conditioning
How Low Back Pain Is Diagnosed
Low back pain is usually diagnosed through a combination of medical history and physical examination. In most cases, a clear diagnosis can be made without extensive investigations.
Medical History
The healthcare provider will ask about:
- Onset and duration of pain
- Location and nature of symptoms
- Activities that aggravate or relieve pain
- Previous episodes of back pain
- Associated symptoms such as numbness, weakness, or stiffness
Physical Examination
During examination, the clinician may:
- Assess posture and spinal mobility
- Check range of motion
- Identify areas of tenderness or muscle tightness
- Evaluate strength, reflexes, and sensation in the lower limbs
Imaging Tests
Imaging tests are not routinely required and are recommended only in selected cases.
- X-ray: Useful for identifying fractures or degenerative bone changes
- MRI: Used to assess discs, nerves, and soft tissues
- CT scan: Reserved for complex or specific diagnostic situations
Most people with low back pain do not need imaging tests.
Treatment Options for Low Back Pain
Treatment depends on the underlying cause, severity, and duration of symptoms. Most individuals recover with conservative management.
Conservative Management
- Activity modification rather than prolonged bed rest
- Physiotherapy to improve mobility, strength, and function
- Regular physical activity and exercise
- Application of heat or ice
- Ergonomic and postural correction
Medications
Medications may be prescribed for symptom relief, including:
- Anti-inflammatory medications
- Short-term muscle relaxants
- Pain relievers
All medications should be taken under medical supervision.
Procedures
In selected cases, interventional procedures such as injections may be considered when conservative treatment fails.
Surgery
Surgical intervention is rarely required and is considered only when:
- Symptoms persist despite adequate conservative treatment
- Progressive neurological deficits are present
- Serious structural pathology is identified
Recovery and Prognosis
The overall prognosis for low back pain is favorable.
- Most people recover within 4 to 6 weeks
- Remaining active supports faster recovery
- Recurrence is common but can be reduced with exercise and lifestyle modification
Long-term outcomes are generally good with appropriate management.
Prevention of Low Back Pain
Preventive strategies include:
- Maintaining good posture
- Avoiding prolonged sitting
- Strengthening core and back muscles
- Using proper lifting techniques
- Maintaining a healthy body weight
- Staying physically active
When to See a Doctor
Medical evaluation is recommended if:
- Pain persists beyond six weeks
- Symptoms worsen despite basic care
- Pain interferes with daily activities
- Numbness, weakness, or tingling develops
- Systemic symptoms such as fever or weight loss occur
Frequently Asked Questions
Is low back pain serious?
Most cases are not serious and resolve with conservative care, but warning signs require prompt evaluation.
How long does low back pain take to heal?
Many people improve within a few weeks, though recovery time varies.
Should I rest or stay active?
Staying active within pain limits is generally preferred over prolonged bed rest.
Can physiotherapy help low back pain?
Yes. Physiotherapy is strongly supported by research for managing and preventing low back pain.
Can low back pain return?
Yes. Recurrence is common, particularly without ongoing exercise and lifestyle changes.
