Back pain is one of the leading causes of disability worldwide, affecting millions of people every year. While occasional soreness after a long day or an intense workout is common, pain that lingers for months is different. Chronic back pain can interfere with work, sleep, exercise, and even simple daily activities like walking, driving, or picking up groceries.

The challenge is that chronic back pain isn't a diagnosis—it's a symptom. Finding the underlying cause is the first step toward effective treatment.

At Anchor Spine & Joint, our orthopedic specialists, interventional pain physicians, and physical therapists work together to identify the source of pain and create treatment plans tailored to each patient. Understanding what's causing your discomfort can help you make informed decisions about your health and avoid unnecessary suffering.

What Is Chronic Back Pain?

Back pain is generally considered chronic when it lasts 12 weeks or longer, even after the original injury has healed.

Some people experience constant pain, while others notice symptoms that come and go. The pain may feel:

• Dull or aching
• Sharp or stabbing
• Burning
• Tight or stiff
• Radiating into the hips or legs
• Worse after sitting or standing
• Worse first thing in the morning

Many patients assume chronic pain is simply part of getting older. While age-related changes can contribute, persistent back pain is not something you should simply "live with."

1. Degenerative Disc Disease

One of the most common causes of chronic back pain is degenerative disc disease.

Despite the name, this isn't actually a disease. It's a natural process that occurs as the spinal discs lose water content over time.

These discs act as cushions between the vertebrae. As they wear down, they become less effective at absorbing shock.

Common symptoms include:

• Lower back pain
• Pain that worsens when sitting
• Morning stiffness
• Pain after bending or lifting
• Episodes of severe flare-ups followed by improvement

Many adults develop some degree of disc degeneration, but not everyone experiences pain. Imaging studies often reveal disc changes in people with no symptoms at all, which is why a thorough physical examination is just as important as MRI findings.

2. Herniated Disc

A herniated disc occurs when the soft center of a spinal disc pushes through its outer layer.

If the disc presses against a nearby nerve, symptoms can include:

• Sharp lower back pain
• Pain traveling down one leg
• Numbness
• Tingling
• Muscle weakness
• Difficulty standing for long periods

Many people refer to this as a "slipped disc," although the disc doesn't actually slip.

Treatment depends on the severity of symptoms. Many patients improve with conservative care, while others benefit from targeted spinal injections or, in certain cases, surgery.

3. Arthritis of the Spine

Osteoarthritis can affect the joints of the spine just as it affects the knees, hips, and hands.

Over time, the protective cartilage wears away, allowing bones to rub together.

Symptoms often include:

• Morning stiffness
• Difficulty twisting
• Pain after prolonged standing
• Decreased flexibility
• Tenderness around the spine

Spinal arthritis often develops gradually and may become more noticeable after age 50, although it can occur earlier following injuries or years of repetitive stress.

4. Spinal Stenosis

Spinal stenosis occurs when the spaces surrounding the spinal cord or nerves become narrower.

As those spaces shrink, nerves can become compressed.

Patients commonly report:

• Pain while walking
• Leg fatigue
• Numbness
• Tingling
• Weakness
• Relief when leaning forward

Many people notice they can walk farther while pushing a shopping cart because bending forward temporarily opens the spinal canal.

Spinal stenosis is especially common in older adults but can often be managed successfully with nonsurgical treatments before surgery becomes necessary.

5. Muscle and Ligament Injuries

Not all chronic back pain originates from the spine itself.

Repeated lifting, sports injuries, poor body mechanics, or physically demanding jobs can strain the muscles and ligaments supporting the back.

Unlike an acute strain that heals within a few weeks, repeated injury can create ongoing inflammation and muscle imbalance.

Signs include:

• Muscle tightness
• Pain during movement
• Tenderness
• Muscle spasms
• Pain that improves with rest but returns during activity

Physical therapy often plays a critical role in restoring strength, flexibility, and proper movement patterns.

6. Sciatica

Sciatica isn't a diagnosis by itself—it's a symptom caused by irritation of the sciatic nerve.

The pain usually begins in the lower back or buttock before traveling down the leg.

Patients often describe it as:

• Burning pain
• Electric shock sensations
• Tingling
• Numbness
• Pain that worsens while sitting
• Weakness in the leg or foot

Sciatica can result from a herniated disc, spinal stenosis, bone spurs, or other conditions that compress the nerve.

Because the underlying causes vary, an accurate diagnosis is essential before beginning treatment.

7. Poor Posture and Sedentary Lifestyle

Modern lifestyles contribute significantly to chronic back pain.

Hours spent sitting at a desk, looking down at a phone, or driving can place continuous stress on the spine.

Poor posture can lead to:

• Muscle fatigue
• Tight hip flexors
• Weak core muscles
• Increased pressure on spinal discs
• Neck and lower back pain

Simple ergonomic improvements, regular movement breaks, strengthening exercises, and physical therapy can often make a meaningful difference.

Risk Factors for Chronic Back Pain

While anyone can develop back pain, certain factors increase the risk.

These include:

• Age
• Obesity
• Smoking
• Physically demanding occupations
• Sedentary lifestyle
• Poor posture
• Previous back injuries
• Osteoporosis
• Repetitive lifting
• Lack of exercise
• Stress and poor sleep

Many patients have several contributing factors rather than one single cause, making a comprehensive evaluation especially important.

When Should You See a Specialist?

Occasional soreness after activity is normal.

However, you should consider scheduling an evaluation if your pain:

• Lasts longer than a few weeks
• Keeps returning
• Radiates into your arms or legs
• Causes numbness or weakness
• Prevents you from working
• Wakes you at night
• Limits daily activities
• Doesn't improve with rest

Early diagnosis often leads to more treatment options and better long-term outcomes.

Frequently Asked Questions

What is the most common cause of chronic back pain?

Degenerative changes in the spine, including arthritis and degenerative disc disease, are among the most common causes. Muscle strain, herniated discs, and spinal stenosis are also frequent contributors.

Can chronic back pain go away without surgery?

Yes. Most patients improve with conservative treatments such as physical therapy, medications, lifestyle changes, or minimally invasive pain management procedures.

How long is back pain considered chronic?

Back pain lasting longer than 12 weeks is generally considered chronic.

When should I worry about chronic back pain?

Seek medical evaluation if your pain lasts several weeks, worsens over time, radiates into your arms or legs, causes numbness or weakness, or interferes with normal daily activities.

What doctor should I see for chronic back pain?

Depending on the cause, you may benefit from seeing an orthopedic spine specialist, an interventional pain management physician, or a physical therapist.

Is walking good for chronic back pain?

For many people, walking is an excellent low-impact exercise that helps improve mobility and strengthen supporting muscles. Your provider can recommend the right activity level based on your condition.

Can poor posture cause chronic back pain?

Yes. Poor posture can increase stress on the spine and surrounding muscles, contributing to persistent discomfort over time.

How is chronic back pain diagnosed?

Diagnosis usually includes a physical examination, review of symptoms, medical history, and, when appropriate, imaging studies such as X-rays or MRI.
