The Most Common Causes of Chronic Back Pain

Back pain is one of the most widespread health complaints in the world, and for many people, it’s not just an occasional twinge, it’s a constant, nagging problem that affects everyday life. If you’ve been experiencing discomfort for weeks or even months, you’re not alone. Chronic back pain, typically defined as pain lasting longer than 12 weeks, affects millions of adults and is one of the leading reasons for doctor visits and missed workdays. At Medwell, we believe the first step to healing is understanding.

What Is Chronic Back Pain?

Before diving into causes, it’s important to clarify what we mean by “chronic” back pain. Acute back pain is sudden and often resolves within a few days or weeks, often due to a specific injury or strain. Chronic back pain, however, persists beyond the normal healing time and may continue for months or even years. The pain might be constant or intermittent, dull or sharp, localized or radiating. Because back pain has many potential triggers, identifying the root cause is crucial for finding the right treatment path.

1. Degenerative Disc Disease

As we age, the discs between our vertebrae begin to wear down. These discs act as shock absorbers, and when they lose hydration or start to shrink, the bones of the spine can rub against each other, leading to stiffness, pain, and limited mobility.

Signs You Might Have It:

  • Pain that worsens when sitting or bending
  • Occasional shooting pain down the legs
  • Morning stiffness that improves with movement

2. Herniated or Bulging Discs

Discs can bulge or rupture, pressing on nearby nerves and causing chronic pain—particularly in the lower back. This is one of the most common causes of back pain in both younger and older adults.

Typical Symptoms:

  • Pain radiating into the buttocks, legs, or feet (sciatica)
  • Tingling or numbness
  • Increased pain when lifting, coughing, or sneezing

3. Muscle Imbalances or Strain

Weak or tight muscles especially in the core and hips—can put uneven pressure on the spine. Over time, poor muscle support can cause structural issues and recurring pain.

Risk Factors:

  • Sedentary lifestyle
  • Poor posture while sitting or working
  • Lifting heavy objects improperly

Even if you don’t recall an injury, subtle strain from everyday movements can lead to chronic discomfort if not addressed.

4. Poor Posture and Body Mechanics

One of the most overlooked causes of chronic back pain is habitual poor posture. Slouching while sitting, standing with uneven weight distribution, or hunching over a phone can place long-term stress on your spine.

Signs Posture May Be a Problem:

  • Pain at the end of the workday
  • Soreness between the shoulder blades
  • Forward head position or rounded shoulders

Addressing posture through physical therapy, ergonomic corrections, and strengthening exercises can make a dramatic difference.

5. Spinal Stenosis

Spinal stenosis occurs when the spinal canal narrows, placing pressure on the spinal cord and nerves. It’s most common in people over 50 and tends to progress slowly.

Common Symptoms:

  • Pain while walking or standing
  • Relief when sitting or bending forward
  • Numbness or weakness in the legs

This condition is often degenerative but manageable with the right intervention.

6. Arthritis and Inflammation

Osteoarthritis can affect the joints in the spine just like the knees or hips. It causes inflammation, cartilage breakdown, and eventually bone-on-bone contact, which leads to chronic back pain.

Signs of Spinal Arthritis:

  • Pain and stiffness in the lower back
  • Symptoms worsen in the morning or after inactivity
  • Mild swelling in the affected area

Inflammatory conditions like ankylosing spondylitis can also cause long-term spinal pain, especially in younger adults.

7. Injuries and Accidents

Falls, car accidents, or sports injuries can cause damage that leads to chronic pain if not properly treated. Even small injuries can result in lingering symptoms due to scar tissue, misalignment, or nerve irritation.

Types of Injuries That Cause Long-Term Pain:

  • Whiplash or soft tissue trauma
  • Vertebral fractures
  • Muscle tears or sprains

Sometimes the original injury heals, but biomechanical compensation causes ongoing issues in surrounding tissues.

8. Lifestyle and Environmental Factors

Sometimes the cause of chronic back pain isn’t a single condition, but a combination of habits and risk factors that gradually wear down the spine over time.

Lifestyle Contributors:

  • Sitting for long periods without breaks
  • Inadequate sleep or sleeping positions
  • Being overweight
  • Smoking (which reduces blood flow to spinal tissues)
  • Stress and tension (which cause muscle tightening)

Many people overlook the impact of daily choices, but small adjustments can significantly reduce pain and inflammation.

9. Psychological and Emotional Stress

Chronic pain isn’t just physical, it often has a mental and emotional component. Stress, anxiety, and depression can intensify the perception of pain and increase muscle tension, creating a cycle of discomfort.

Possible Clues:

  • Back pain worsens during stressful events
  • Poor sleep or fatigue
  • History of anxiety or trauma

Mind-body approaches like meditation, cognitive-behavioral therapy, or yoga can play a vital role in managing both the emotional and physical aspects of chronic pain.

10. Underlying Health Conditions

In rare cases, chronic back pain may signal a more serious issue, such as:

  • Kidney stones or infections
  • Endometriosis (pain referred to the back)
  • Spinal tumors or infections
  • Autoimmune conditions

If your back pain is accompanied by unexplained weight loss, fever, or bowel/bladder issues, consult a medical professional immediately.

When to See a Specialist

While occasional back pain is common, chronic pain shouldn’t be ignored. Here are some signs it’s time to consult a pain specialist:

  • Pain that lasts more than 12 weeks
  • Pain interfering with sleep or daily activities
  • Pain accompanied by numbness or weakness
  • No relief from rest, stretching, or over-the-counter medications
