We’re here to walk you through common causes and evidence-informed treatment options that may help alleviate the ache in your lower back.

7 possible causes of lower back pain

Lower back pain can come from a variety of sources. In many cases, it’s not just one issue but a combination of factors. 

1. Muscle strain or overuse

Strained muscles are one of the most common causes of lower back pain. The injury can happen from:

• Lifting something heavy

• Sudden movements

• Repetitive activities

• Poor posture over time

This type of pain is often described as soreness or tightness and may improve with rest and movement over time.

2. Poor posture and prolonged sitting 

3. 
   

Spending long hours sitting — especially with unsupported posture — can place stress on the lower back. Over time, this may lead to:

• Muscle imbalances

• Reduced mobility

• Increased stiffness

If you work at a desk or drive frequently, this may be a contributing factor to your back pain.

3. Herniated or bulging discs

Spinal discs act as cushions between the bones in your spine. A disc may bulge or herniate when its inner material pushes outward.

This can sometimes irritate nearby nerves and may be associated with:

• Pain that travels down the leg

• Numbness or tingling

• Weakness in certain movements

If symptoms persist or worsen, it may be helpful to seek evaluation from a physical therapist.

4. Joint dysfunction

The joints in your spine, including facet joints and the sacroiliac joint, can become stiff or irritated from causes including gradual wear and tear over time and repetitive stress from physical activities.

This may lead to:

• Localized lower back pain

• Pain with certain movements or positions

• Difficulty bending or twisting

• Degenerative changes 

As we age, natural changes in the spine can occur, such as disc degeneration or arthritis. These changes are common and don’t always cause pain. But in some cases, they may be associated with stiffness or discomfort.

6. Weak core and stability muscles 

Your core muscles help support your spine. If these muscles aren’t working efficiently, your lower back may take on more strain during daily activities.

This may contribute to:

• Ongoing discomfort

• Reduced movement control

• Increased risk of flare-ups

• Stress and tension 

Physical pain and emotional stress can be connected. Some people experience increased muscle tension in the lower back during periods of stress, which may contribute to discomfort. 

Lower back pain treatment options 

If you’re looking for lower back pain treatment, it’s helpful to understand what options are available and how they may support your recovery. 

• Manual therapy

Hands-on techniques may be used to improve joint and soft tissue mobility. This can include:

• Joint mobilization

• Soft tissue work

• Techniques such as the McKenzie Method® 

These approaches are often combined with exercise for a more comprehensive plan.

• Targeted exercise programs

Exercise plays a key role in recovery and long-term management. Programs may include:

• Core strengthening

• Stretching

• Functional movement training

Rather than a one-size-fits-all routine, exercises are typically tailored to your specific condition and goals.

• Education and activity modification 

Understanding your pain — and how to move safely — can make a meaningful difference.

A physical therapist may guide you on:

• Safe ways to lift and move

• Adjustments to your daily routine

• Strategies to stay active without worsening symptoms
