Chronic Back Pain: Causes, Symptoms, Diagnosis, and Treatment Options

Chronic back pain can affect nearly every part of daily life, from getting out of bed in the morning to working, exercising, sleeping, and spending time with family. While occasional back pain is common, pain that lasts for weeks or continues to return may signal an underlying condition that requires a closer evaluation.

Understanding what causes chronic back pain, how it is diagnosed, and which treatment options are available can help patients make informed decisions about their care.

What Is Chronic Back Pain?

Chronic back pain is generally defined as back pain that lasts for 12 weeks or longer. The pain may begin after an injury, develop gradually over time, or continue even after an initial injury has healed.

Chronic back pain can affect the lower back, middle back, or, less commonly, the upper back. It may remain localized to the back or extend into the buttocks, hips, legs, or feet when nerves are involved.

Unlike short-term back pain, chronic pain can be more complex because multiple factors may contribute to its persistence.

What Causes Chronic Back Pain?

What causes chronic back pain can vary significantly from one person to another. Common causes include changes to the discs, joints, muscles, bones, and nerves of the spine.

Some of the most common causes include:

• Degenerative disc disease: Spinal discs can lose hydration and flexibility as they age, potentially contributing to pain.
• Herniated or bulging discs: A damaged or displaced disc can irritate nearby spinal nerves.
• Spinal stenosis: Narrowing within the spinal canal or nerve passageways can place pressure on nerves.
• Facet joint arthritis: Wear and inflammation in the small joints located along the back of the spine can cause localized back pain.
• Sacroiliac joint dysfunction: Problems involving the joints connecting the spine and pelvis can produce pain in the lower back, buttocks, or hips.
• Vertebral endplate damage: Changes in the vertebral endplates can cause a specific type of lower back pain known as vertebrogenic pain.
• Muscle or ligament injuries: Repeated strain, poor lifting mechanics, or an acute injury can contribute to persistent pain.
• Spondylolisthesis: One vertebra can shift relative to another, sometimes causing back pain and nerve symptoms.
• Previous spine surgery: Some patients continue to experience pain following spine surgery, sometimes referred to as persistent spinal pain or failed back surgery syndrome.

In some cases, chronic back pain does not have one identifiable cause. A comprehensive evaluation can help determine which structures may be contributing to symptoms.

What Are the Symptoms of Chronic Back Pain?

Chronic back pain can feel different depending on its underlying cause. Some patients experience a constant dull ache, while others describe sharp, burning, or shooting pain.

Common symptoms may include:

• Persistent aching or stiffness in the back
• Sharp or stabbing pain with certain movements
• Pain that worsens after sitting or standing for long periods
• Reduced flexibility or range of motion
• Muscle tightness or spasms
• Pain extending into the buttocks or hips
• Numbness, tingling, or weakness in the legs
• Pain that becomes worse with coughing, sneezing, bending, or lifting

Symptoms involving the legs can sometimes indicate irritation or compression of a spinal nerve.

When Should Someone See a Doctor for Back Pain?

Not every episode of back pain requires immediate medical attention. However, persistent, worsening, or recurring pain should be evaluated, particularly when it interferes with normal activities.

Patients should seek prompt medical attention for back pain accompanied by symptoms such as significant weakness, loss of bladder or bowel control, numbness around the groin or inner thighs, fever, unexplained weight loss, or severe pain following significant trauma.

These symptoms can sometimes indicate a more serious underlying problem requiring urgent evaluation.

How Is Chronic Back Pain Diagnosed?

Diagnosing chronic back pain typically begins with a medical history and physical examination. A provider may ask when the pain started, where it is located, what makes it better or worse, and whether symptoms travel into the legs.

The physical examination may evaluate movement, muscle strength, reflexes, sensation, and other signs that can help identify potential nerve involvement.

Imaging may also be recommended. Depending on the patient’s symptoms and medical history, diagnostic testing can include:

• X-rays to evaluate the bones, alignment, and signs of arthritis or other structural changes.
• MRI scans to provide detailed images of discs, nerves, the spinal cord, and surrounding soft tissues.
• CT scans to provide detailed images of spinal bones and certain structural abnormalities.
• Diagnostic injections that may help determine whether a particular joint or structure is contributing to pain.

Importantly, imaging findings do not always explain a person’s symptoms. Many age-related spinal changes can appear on imaging even in people who do not have significant pain. Diagnosis therefore involves considering imaging findings alongside symptoms and physical examination results.

What Are the Treatment Options for Chronic Back Pain?

Treatment depends on the suspected source of pain, the severity of symptoms, overall health, and previous treatments. In many cases, treatment begins with conservative approaches before more advanced interventions are considered.

Physical Therapy and Exercise

Physical therapy can help improve flexibility, strength, posture, movement patterns, and core stability. A customized exercise program may also help patients return to daily activities while reducing strain on the spine.

Remaining physically active within appropriate limits is often an important part of long-term back pain management.

Lifestyle Changes

Certain lifestyle factors can influence back pain. Maintaining a healthy weight, improving ergonomics at work, avoiding prolonged periods in one position, and using proper lifting techniques may help reduce stress on the spine.

Sleep habits and regular physical activity can also play an important role in managing chronic pain.

Interventional Pain Procedures

When conservative treatment does not provide sufficient relief, interventional pain procedures may be considered. Depending on the suspected pain generator, options can include epidural steroid injections, facet joint injections, sacroiliac joint injections, radiofrequency ablation, or other targeted procedures.

These treatments are designed to address specific sources of pain and may be used as part of a broader treatment plan.

Minimally Invasive Procedures

Some spinal conditions may respond to minimally invasive procedures designed to address specific structural problems without traditional open surgery.

For example, certain patients with vertebrogenic low back pain may be candidates for basivertebral nerve ablation. Patients with spinal stenosis or other structural conditions may have additional minimally invasive treatment options depending on their diagnosis.

Spinal Cord Stimulation

For certain patients with persistent chronic nerve pain who have not achieved adequate relief with other treatments, spinal cord stimulation may be an option.

Spinal cord stimulation uses an implanted device to deliver electrical signals near the spinal cord. A temporary trial is typically performed before permanent implantation to determine whether the therapy provides meaningful pain relief.

Surgery

Surgery is not necessary for most cases of chronic back pain. However, it may be recommended when there is a significant structural problem, progressive neurological impairment, spinal instability, or another condition that is unlikely to improve with nonsurgical treatment.

A spine specialist can help determine whether surgery is appropriate and whether less invasive options should be considered first.

Can Chronic Back Pain Be Prevented?

Not every cause of chronic back pain can be prevented, particularly age-related changes to the spine. However, several habits may help reduce the risk of developing or worsening back problems.

Regular physical activity, maintaining strength and flexibility, practicing proper lifting techniques, avoiding prolonged inactivity, and maintaining a healthy weight can all support spinal health.

Early evaluation of recurring back pain may also help identify problems before symptoms become more difficult to manage.

What Should Someone Do About Chronic Back Pain?

Chronic back pain should not simply be accepted as an unavoidable part of aging. Because back pain can have many different causes, identifying the source is an important first step toward choosing an appropriate treatment.

Patients who experience persistent or recurring back pain should consider discussing their symptoms with a qualified healthcare provider or pain management specialist. A thorough evaluation can help determine whether conservative care, interventional treatment, minimally invasive procedures, or another approach may be appropriate.
