Do I Need an X-Ray or MRI for Back Pain?
Short Answer
Not necessarily.
Most people with low back pain do not need an X-ray or MRI right away. In many cases, imaging does not change treatment recommendations or improve outcomes.
Dr. Ethan Marler, Chiropractor, follows an evidence-informed approach to assessment. For many common episodes of back pain, a thorough history and physical examination provide more useful information than immediate imaging. However, there are situations where X-rays, MRI scans, or referral for additional medical evaluation may be appropriate. The goal is to determine whether imaging is likely to provide information that will meaningfully influence decision-making and care.
Why This Question Matters
Many people assume that if their back hurts, imaging will reveal the exact cause.
Unfortunately, it is often not that simple.
Research has shown that many people without back pain have findings on imaging such as:
Disc bulges
Disc degeneration
Arthritis
Joint changes
Disc protrusions
These findings often become more common as people age and may not be responsible for symptoms.
For example, an MRI may show age-related changes that sound concerning but are not actually causing pain.
This is one reason healthcare providers are often cautious about ordering imaging unless there is a clear reason to do so.
The goal is not to ignore symptoms. The goal is to use imaging when it is likely to help answer an important clinical question.
What May Help
If your back pain is relatively recent and not accompanied by concerning symptoms, many people benefit from:
Remaining active as symptoms allow
Continuing normal daily activities when possible
Avoiding prolonged bed rest
Gradually returning to movement and exercise
Monitoring whether symptoms are improving over time
Many episodes of back pain improve without requiring imaging.
If symptoms persist, worsen, significantly limit function, or are accompanied by other concerning findings, an assessment may help determine whether additional investigation is appropriate.
Dr. Marler’s Approach
Dr. Marler does not routinely assume that imaging is required simply because someone has back pain.
Instead, he focuses on understanding:
The patient's symptoms
Functional limitations
Activity goals
Medical history
Injury history
Neurological findings
Movement tolerance
During an assessment, he looks for signs that may indicate whether imaging could be helpful or whether a conservative approach is more appropriate.
If there are concerns that warrant further investigation, Dr. Marler may recommend referral to the appropriate healthcare provider for additional assessment or imaging.
His goal is to help patients understand what is happening, avoid unnecessary fear about imaging findings, and make decisions based on the individual's presentation rather than assumptions.
When to get Assessed
It may be worth booking an assessment if:
Back pain is affecting work or daily activities
Symptoms are not improving
Pain repeatedly returns
You are unsure whether imaging may be appropriate
You want guidance on returning to activity safely
When to Seek Urgent Medical Care
Seek prompt medical assessment if back pain is accompanied by:
Loss of bowel or bladder control
Numbness in the groin or saddle area
Significant or worsening leg weakness
Major trauma
Unexplained weight loss
Fever or signs of infection
History of cancer with new unexplained back pain
Other serious neurological symptoms
These situations may require urgent medical evaluation and potentially imaging.
Frequently asked questions
-
Low back pain is one of the most common reasons people seek healthcare, and it can develop for many different reasons.
In many cases, low back pain is not caused by a single structure, injury, or event. Symptoms are often influenced by a combination of factors such as activity levels, work demands, training volume, recovery, sleep, stress, previous injuries, and overall physical capacity.
Sometimes symptoms begin after lifting, bending, exercising, or spending long periods sitting. Other times there is no obvious trigger.
Dr. Marler often explains that pain does not always tell us exactly what structure is responsible. Instead of focusing solely on finding a single cause, he focuses on understanding how symptoms are affecting function and what factors may be contributing to the problem.
For most people, the goal is not simply identifying a diagnosis but helping them return to meaningful activities with greater confidence and capacity.
-
Many people notice their back feels worse after sitting for long periods, especially during work, commuting, or leisure activities.
Often, the issue is not sitting itself but the amount of time spent in one position. The body generally tolerates movement and position changes better than prolonged stillness.
Sitting may become uncomfortable because of:
Reduced movement
Increased sensitivity of irritated tissues
Reduced tolerance to certain positions
Recent increases in workload or stress
Existing back pain
Interestingly, there is no single "perfect" sitting posture that works for everyone. People often feel better when they change positions regularly rather than trying to maintain one ideal posture all day.
Dr. Marler frequently encourages patients to think less about finding the perfect sitting position and more about creating opportunities to move throughout the day.
-
For many people, yes.
Walking is often a well-tolerated form of movement that can help people stay active while experiencing low back pain. It promotes circulation, encourages movement, and can help reduce the tendency to avoid activity altogether.
That said, not every person responds the same way. Some people feel better while walking, while others may notice symptoms increase depending on the nature of their condition.
Dr. Marler typically encourages people to focus on what movements they can do rather than only focusing on what they cannot. Walking is often a useful starting point because it is accessible, scalable, and easy to modify based on symptoms.
The goal is usually not to find one magic exercise. The goal is to gradually rebuild confidence and capacity so the body can tolerate everyday activities more comfortably.
-
Most episodes of back pain are not caused by serious medical conditions and improve over time.
However, some situations warrant prompt medical attention.
Examples include:
Significant trauma
Progressive weakness
Loss of sensation
Difficulty controlling bowel or bladder function
Unexplained weight loss
Fever accompanied by back pain
Severe or rapidly worsening symptoms
For non-emergency situations, it may be worth seeking assessment if back pain is interfering with work, exercise, sleep, or daily activities, or if symptoms are not improving as expected.
Dr. Marler's approach is to help patients understand what is common, what may require further investigation, and what steps can help them safely return to meaningful activities. Often, reassurance and education can be just as important as treatment itself.
