Low Back Pain: Why It Happens and How We Approach It

Low back pain can be frustrating-especially if you cannot figure out why it started.

Often patients will say:

“I just woke up with it one morning.”

“I bent over to put on my sock and suddenly felt a sharp pain.”

“I didn't really do anything. Why does my back hurt?”

Those are reasonable questions.

If you have bent over to put your socks on thousands of times without pain, one ordinary movement may not fully explain why your back suddenly became painful. Sometimes that movement is simply the moment when an irritated or sensitive area becomes noticeable.

Low back pain is also more complicated than identifying one damaged structure. About 90% of low back pain is classified as nonspecific, meaning it cannot be confidently attributed to one specific disease or anatomical structure (World Health Organization [WHO], 2023a). Researchers likewise emphasize that, for most people with low back pain, an exact pain-generating tissue cannot be identified with certainty (Hartvigsen et al., 2018). World Health Organization

That does not mean your pain is unexplained, imaginary, or something you simply need to live with.

It means that understanding low back pain usually requires looking at the whole clinical picture rather than assuming that one structure is always responsible.

A note about sciatica: This page focuses primarily on low back pain that remains in the low-back region. If your symptoms travel into the buttock or leg, or include numbness or tingling, our dedicated Sciatica page discusses those presentations in greater detail.

Why Can Low Back Pain Seem to Start Out of Nowhere?

For many people, there is no dramatic injury.

Instead, symptoms may appear during a period when the back has been exposed to different demands than usual.

That might include:

  • Sitting significantly more than normal

  • Repetitive bending or lifting

  • A sudden increase in exercise or physical work

  • Returning to an activity after time away

  • Prolonged positions

  • Reduced activity

  • Changes in sleep or recovery

  • Previous episodes of low back pain

Then one ordinary movement seems to trigger the episode.

You bend over.

You get out of your car.

You stand up from a chair.

You put on a shoe.

The movement may have provoked the symptoms, but that does not necessarily mean that movement caused a major injury.

Low back pain is influenced by a combination of physical, biological, occupational, psychological, social, and lifestyle factors. Previous episodes of pain, work demands, physical activity, general health, sleep, and other individual factors can influence both the development and persistence of symptoms (Hartvigsen et al., 2018). PubMed

That is why our evaluation looks beyond the exact second your pain began.

What Can Contribute to Low Back Pain?

There is no single explanation that applies to everyone.

The lumbar spine contains discs, joints, muscles, ligaments, and other tissues that work together to create movement and tolerate load. Different structures or functional problems may contribute to symptoms in different people.

In many cases, we think in terms of patterns and likely contributors rather than pretending that one examination maneuver can identify the precise tissue responsible for every person's pain.

A 2023 systematic review evaluating clinical tests for disc-, facet-joint-, and sacroiliac-joint-related low back pain found that some examination findings can increase or decrease the likelihood that particular structures are involved, but diagnosis remains imperfect (Han et al., 2023). PubMed

Here are some of the patterns we commonly consider.


1. Disc-Related Low Back Pain

Between each of the vertebrae in your spine is an intervertebral disc.

The disc has a strong outer portion called the annulus fibrosus surrounding a softer central portion called the nucleus pulposus.

Discs help:

  • Distribute forces through the spine

  • Allow movement between vertebrae

  • Absorb and transfer loads during daily activity

Like other tissues in your body, discs respond to movement and loading.

For some people with localized low back pain, examination findings suggest that a disc may be contributing to the symptoms. However, determining that a disc is the pain source is not as simple as identifying a disc bulge on an MRI or finding one painful movement (Han et al., 2023). PubMed

One useful part of the examination is observing how your pain changes when you repeatedly move your spine in different directions.

Some patients demonstrate a directional preference. This means that a particular direction of movement consistently:

  • Decreases pain

  • Improves movement

  • Makes an activity easier

  • Or produces another meaningful improvement in symptoms or function

Directional preference is a recognized clinical phenomenon, although it is not present in every patient and should not be assumed before examination (May et al., 2018). PubMed

For example, one person's back may feel substantially better after repeated extension movements. Another person's symptoms may respond differently.

That is why we test rather than guess.


2. Joint-Related Low Back Pain

The lumbar vertebrae are also connected by small joints called facet joints.

These joints help guide spinal movement and share load as you bend, extend, and rotate.

For some patients, these joints appear to contribute to localized low back pain.

Certain movements or positions may be uncomfortable, and the examination may reveal restricted or painful spinal motion. However, there is no single symptom or routine physical examination test that can prove with certainty that a facet joint is the source of someone's pain (Han et al., 2023). PubMed

Instead, we consider:

  • Where the pain is located

  • Which movements reproduce it

  • Which movements are restricted

  • Whether particular positions improve or worsen symptoms

  • How the spine is moving overall

  • How the patient responds to treatment

This information helps us determine whether improving spinal motion may be useful as part of the treatment plan.


3. Muscle and Soft-Tissue Pain

The muscles surrounding your low back and pelvis work constantly throughout the day.

They help you:

  • Maintain posture

  • Lift

  • Bend

  • Walk

  • Exercise

  • Transfer forces between your upper and lower body

During an episode of low back pain, these muscles may become painful, sensitive, or guarded.

Sometimes patients describe:

  • Tightness

  • Aching

  • Muscle spasms

  • Fatigue

  • Tenderness

  • A sensation that the back is “locked up”

Muscular symptoms do not necessarily mean that the muscle itself is the entire cause of the problem.

Guarding can also be the body's response to another painful or sensitive structure.

That distinction matters because simply trying to “loosen the muscles” may provide temporary relief without addressing the movement or loading problem that contributed to the symptoms.


4. Movement, Strength, and Load Tolerance

Sometimes the most useful finding isn't one specific painful tissue.

It's discovering what your back is having difficulty doing.

For example, one patient may struggle to control their trunk during lifting.

Another may have adequate strength but poor muscular endurance.

Another may have restricted hip mobility that changes how they move through their lumbar spine.

Another may feel fine during normal daily activity but develop pain whenever their workload suddenly increases.

We may evaluate:

  • Trunk strength and endurance

  • Movement coordination

  • Hip mobility

  • Spinal mobility

  • Lifting mechanics

  • Balance and control

  • Tolerance to sustained positions

  • Activities specific to your work, exercise, or sport

This helps us determine what needs to improve, rather than simply telling every person with back pain that they have a “weak core.”

Exercise guidelines for low back pain include several different approaches, including trunk strengthening and endurance, movement-control exercise, specific trunk-muscle activation, aerobic exercise, and other forms of progressive activity (George et al., 2021). PubMed

The right choice depends on the individual.

What About Arthritis and Degenerative Disc Disease?

This is an especially important subject because many patients arrive at our office after having an X-ray or MRI.

They may have been told they have:

  • Degenerative disc disease

  • Disc bulges

  • Facet arthritis

  • Loss of disc height

  • Bone spurs

  • Other “wear-and-tear” changes

Those findings can sometimes be relevant.

But they don't automatically explain why your back hurts.

A large systematic review examined imaging findings in people without back pain and found that degenerative changes become increasingly common with age. Findings such as disc degeneration, disc bulges, and facet degeneration can therefore be present in people who feel perfectly well (Brinjikji et al., 2015). PubMed

At the same time, another systematic review found that several degenerative MRI findings occur more frequently in people with low back pain than in people without pain, meaning imaging findings should not simply be dismissed either (Brinjikji et al., 2015). PubMed

The important concept is context.

An MRI finding may matter.

It may also represent a common age-related finding that is not the primary reason you're currently hurting.

That is why we compare imaging—when imaging is appropriate—with:

  • Your symptoms

  • Your history

  • Your examination

  • Your movement

  • Your function

Your imaging is one piece of the puzzle, not necessarily the entire answer.

How We Evaluate Low Back Pain

At Warner Chiropractic, we don't begin treatment by assuming that everyone with low back pain has the same condition.

We first want to understand your presentation.

Step 1: Listen to Your Story

Your history gives us important information.

We may ask:

  • When did your pain begin?

  • Was there an injury?

  • Have you experienced this before?

  • What movements make it worse?

  • What makes it feel better?

  • Is sitting uncomfortable?

  • What happens when you walk?

  • Does bending bother you?

  • Does standing bother you?

  • Is your sleep affected?

  • Has your activity recently changed?

  • What activities can you no longer do comfortably?

  • Most importantly, what do you want to get back to doing?

Those answers help determine what we examine next.

Step 2: Make Sure the Presentation Is Appropriate for Conservative Care

Most low back pain is musculoskeletal and does not represent a dangerous condition.

But part of evaluating back pain is recognizing when further investigation may be necessary.

Your history and examination help us screen for findings that could suggest conditions such as fracture, infection, cancer, or another problem requiring additional medical evaluation.

Current guidelines generally recommend against routine imaging for uncomplicated low back pain unless the history or examination suggests a serious underlying condition or imaging is otherwise likely to change management (Department of Veterans Affairs & Department of Defense, 2022). Health Quality

That means an X-ray or MRI is not automatically necessary simply because your back hurts.

Step 3: See How Your Back Moves

Next, we examine how your spine and surrounding regions function.

Depending on your presentation, this may include:

  • Lumbar range of motion

  • Repeated-movement testing

  • Hip mobility

  • Trunk strength

  • Muscular endurance

  • Movement coordination

  • Palpation

  • Orthopedic testing

  • Functional movements

  • Neurological testing when appropriate

We're not simply asking:

“Which test hurts?”

We're asking:

“What information does this give us about how your back is functioning?”

If a movement consistently makes you feel better, that's useful.

If another position consistently provokes your pain, that's useful too.

If we identify a mobility, strength, endurance, or movement-control deficit, that can help determine what we should address.

How We Treat Low Back Pain

After the examination, we explain what we found and develop a plan with you.

There isn't one Warner Chiropractic “low-back-pain protocol.”

Two people can walk into our office with pain in almost the exact same location and leave with different exercises and treatment recommendations.

That's intentional.


Exercise Based on Your Examination

Exercise is an important component of managing many presentations of low back pain.

But simply saying “exercise is good for back pain” isn't specific enough.

The exercise needs to make sense for the person.

Depending on what we find, your program may emphasize:

  • Direction-specific movements

  • Mobility

  • Trunk strength

  • Muscular endurance

  • Movement control

  • Hip strength

  • Progressive resistance

  • Lifting mechanics

  • Gradual return to normal activity

Clinical practice guidelines support several types of exercise for low back pain rather than identifying one universally superior exercise program (George et al., 2021; WHO, 2023b). PubMed

Our goal is not to hand every patient the same sheet of generic “core exercises.”

It's to identify what you need to work on.


Chiropractic Manipulation and Mobilization

When appropriate, chiropractic manipulation or mobilization may be incorporated into your treatment.

Manual treatment may help reduce symptoms and improve function or make movement more comfortable for some people with low back pain.

Spinal manipulation is included among nonpharmacologic treatment options in major low-back-pain clinical practice guidelines (George et al., 2021; Qaseem et al., 2017). PubMed

But we don't view an adjustment as the entire solution.

If treatment allows you to move more comfortably, the next question is:

What can we do with that improved movement?

That might mean reinforcing it with:

  • Exercise

  • Strengthening

  • Movement practice

  • Gradual return to activity

The hands-on care and active care should support one another.


Soft-Tissue Treatment

Muscles around a painful area commonly become sensitive or guarded.

When appropriate, soft-tissue techniques may be incorporated to:

  • Reduce discomfort

  • Improve tolerance to movement

  • Address areas of muscular tenderness

  • Help a patient participate more comfortably in active rehabilitation

These treatments are typically used as part of a broader treatment strategy, rather than as the entire solution to low back pain.


Other Treatment Options

Depending on your examination and individual needs, we may also incorporate other services available in our office as an adjunct to the primary treatment plan.

The important word is adjunct.

Passive treatment can sometimes help someone feel and move better, but our long-term goal is to help you restore function and develop strategies you can use independently.

Why Education Is Part of Treatment

We want you to leave our office understanding your back better than when you walked in.

That means understanding:

  • What we found during your examination

  • What appears to aggravate your symptoms

  • What seems to improve them

  • Which exercises you should perform

  • Which activities you can continue

  • Whether anything needs to be temporarily modified

  • How we plan to progress your activity

  • What you can do if symptoms begin returning

Modern low-back-pain recommendations emphasize education, remaining active, exercise, and self-management as important parts of care (WHO, 2023b). World Health Organization

We don't want to make you afraid of your back.

We want to help you understand it.

Our Goal: Get You Back to Doing What You Love

Improvement means different things to different people.

Maybe you want to:

  • Sleep through the night

  • Pick up your child or grandchild

  • Work without constantly thinking about your back

  • Sit comfortably during a long car ride

  • Get back to the gym

  • Golf

  • Run

  • Garden

  • Travel

  • Work around the house

Those goals matter.

They give treatment a purpose.

Our job is to identify what appears to be limiting you, help reduce the barriers that are preventing comfortable movement, and progressively improve your ability to tolerate the activities that matter to you.

Sometimes that involves hands-on care.

Sometimes it involves changing how you move.

Sometimes it involves improving strength or endurance.

Sometimes the most important first step is simply helping someone understand that their back is capable of recovering.

Most often, it involves a combination.

Struggling With Low Back Pain?

If localized low back pain is keeping you from working, exercising, sleeping comfortably, or doing the things you enjoy, we'd be happy to evaluate what's going on and develop a plan based on your individual presentation and goals.
