Understanding
Chronic Back Pain

Many cases of chronic back pain are caused by muscle strain, age-related changes in the spine or other mechanical problems. However, persistent back pain can also be a symptom of an underlying rheumatic, autoimmune or inflammatory condition. Understanding how your symptoms present, including when the pain occurs, what makes it better or worse, and whether it is accompanied by other symptoms, can help identify the underlying cause and guide appropriate treatment.

What Defines Chronic Back Pain?

What Defines Chronic
Back Pain?

Chronic back pain is generally defined as back pain that lasts for more than 12 weeks. It may develop gradually or begin after an injury, and the symptoms vary depending on the underlying cause.

 

Chronic back pain may present as:

  • Persistent aching or discomfort in the lower, middle or upper back
  • Stiffness, particularly after resting or first thing in the morning
  • Pain that worsens with prolonged sitting, standing or certain movements
  • Pain that improves or worsens with physical activity, depending on the cause
  • Pain that radiates into the buttocks or legs
  • Reduced flexibility or difficulty bending, twisting or lifting
  • Disrupted sleep due to persistent discomfort

When chronic back pain is caused by an inflammatory rheumatic condition, it often behaves differently from mechanical back pain.
Rather than improving with rest, the pain may be worse after inactivity and gradually ease with movement or exercise.

What Can Cause Chronic Back Pain?

Persistent back pain can arise from problems affecting the muscles, joints, discs, ligaments or bones of the spine. In some cases, it may also result from inflammation caused by an autoimmune or rheumatic condition.

01

Muscle Strain and Mechanical Back Pain

Muscle strains, ligament injuries and poor posture are among the most common causes of chronic back pain. Repetitive lifting, prolonged sitting, physically demanding work or inadequate core muscle support can all contribute to ongoing mechanical back pain. Symptoms often worsen with certain movements or activities and typically improve with rest.

02

Degenerative Spine Conditions

As we age, the structures of the spine naturally undergo wear and tear. Conditions such as degenerative disc disease, facet joint osteoarthritis and spinal stenosis can lead to chronic back pain, stiffness and reduced mobility. These conditions are generally more common in older adults but can also develop earlier following previous injuries or repetitive strain.

03

Spinal Injury or Structural Problems

Previous spinal injuries, vertebral fractures, scoliosis, spondylolisthesis or other structural abnormalities can place additional stress on the spine and surrounding tissues, resulting in persistent back pain. Depending on the underlying problem, symptoms may remain stable or gradually worsen over time.

04

Rheumatic and Autoimmune Conditions

Inflammatory rheumatic diseases can cause chronic back pain when the immune system mistakenly attacks the joints, ligaments or tissues of the spine. Unlike mechanical back pain, inflammatory back pain often develops gradually, begins before the age of 45 and is associated with prolonged morning stiffness. It typically improves with activity rather than rest and may occur alongside symptoms affecting other joints, the eyes, skin or digestive system.

When Could Chronic Back Pain Be a Sign of a Rheumatic Condition?

While most cases of chronic back pain are not caused by autoimmune disease, certain features may suggest an underlying inflammatory condition that requires specialist assessment.

Signs that your chronic back pain may be related to a rheumatic condition include:

Leaf

Pain lasting for more than three months

Leaf

Symptoms beginning before the age of 45 without a clear injury

Leaf

Morning stiffness lasting longer than 30 minutes

Leaf

Pain that improves with movement or exercise rather than rest

Leaf

Pain that wakes you during the second half of the night

Leaf

Alternating pain in the buttocks

Leaf

Swollen joints, heel pain or tendon inflammation

Leaf

Psoriasis, inflammatory bowel disease or recurrent eye inflammation

Leaf

Persistent fatigue or other unexplained inflammatory symptoms

Leaf

A family history of inflammatory arthritis or autoimmune disease

Several rheumatic conditions may cause chronic back pain, including:

Axial Spondyloarthritis

A chronic inflammatory condition that primarily affects the spine and sacroiliac joints, leading to persistent back pain and stiffness that may improve with movement.

Psoriatic Arthritis

An inflammatory condition associated with psoriasis that can affect the spine and sacroiliac joints, leading to persistent back pain and stiffness.

Rheumatoid Arthritis

An autoimmune condition that mainly affects peripheral joints but can sometimes involve the cervical spine, leading to persistent neck pain and stiffness.

Osteoarthritis

A degenerative joint condition that can affect the joints of the spine, leading to persistent back pain, stiffness and reduced mobility.

Lupus

A systemic autoimmune condition that can cause joint and muscle pain, which may contribute to persistent back discomfort even when the spine itself is not affected.

Other autoimmune and inflammatory conditions, including connective tissue diseases, vasculitis and reactive arthritis, may also contribute to back pain. As back pain can have many possible causes, specialist evaluation may help determine whether an underlying rheumatic condition is involved.

How Do Rheumatologists Diagnose the Cause of Chronic
Back Pain?

Chronic back pain has many possible causes, and identifying the underlying problem begins with a thorough assessment of your symptoms, medical history and physical examination.

01

Clinical Assessment

Your rheumatologist will ask about when your pain started, where it is located, what makes it better or worse, how it affects your daily activities and whether you have other symptoms such as joint pain, skin rashes, eye inflammation or bowel problems. A physical examination will assess your posture, spinal movement, flexibility, joint function and areas of tenderness.

02

Blood Tests

Blood tests may help identify signs of inflammation or autoimmune disease. Depending on your symptoms, your doctor may request inflammatory markers such as ESR and CRP, autoimmune antibody tests or HLA-B27 testing, which may support the diagnosis of certain inflammatory spinal conditions.

03

Imaging Studies

Imaging plays an important role in determining the cause of chronic back pain. X-rays can identify degenerative changes or structural abnormalities, while MRI scans are particularly useful for detecting early inflammation of the spine and sacroiliac joints before permanent damage develops.

04

Additional Investigations

Depending on your symptoms and examination findings, additional tests may sometimes be required to evaluate your nerves, bone health or other underlying conditions contributing to your back pain. These investigations help build a more complete picture before treatment is recommended.

Depending on the findings from your consultation and investigations, your rheumatologist will combine this information to determine the most likely cause of your chronic back pain, and identify whether your symptoms are mechanical, degenerative or inflammatory.

Comprehensive Assessment for Chronic Back Pain with
Dr Anindita Santosa

Chronic back pain can arise from mechanical problems, age-related changes or underlying inflammatory rheumatic conditions. When pain persists for months, particularly when accompanied by prolonged morning stiffness or other inflammatory symptoms, identifying the underlying cause can help ensure you receive appropriate treatment and prevent symptoms from unnecessarily limiting your daily activities.

 

At Aaria Rheumatology, patients receive personalised assessment and care for chronic back pain that may be related to rheumatic conditions. As a rheumatologist, Dr Anindita Santosa evaluates your symptoms and investigation findings to determine whether inflammation or an underlying rheumatic condition may be contributing to your pain.
