Back Pain:
What It Is and How It Is Treated
Back pain is one of the most common reasons people seek medical care. Although it can significantly interfere with work, sleep, mobility, and everyday activities, most episodes improve with appropriate treatment and continued movement.
Back pain affects approximately 619 million people worldwide and is the leading cause of disability globally. About four in ten adults will experience an episode of back pain during their lives. It becomes more common with age and occurs somewhat more frequently in women.
What Causes Back Pain?
In approximately 90% of people who seek care for back pain, no single structure can be identified as the sole source of the symptoms. This is known as nonspecific back pain.
Nonspecific back pain does not mean that the pain is not real or that something has been missed. It often results from a combination of factors, including:
-
Muscle or joint strain
-
Normal age-related changes in the spine
-
Changes in activity level
-
Poor sleep
-
Stress
-
Mood
-
Physical deconditioning
-
Repetitive movement or overuse
A smaller group of patients have back pain caused by a specific condition, such as:
-
A bulging or herniated disc pressing on a nerve, which may cause pain, numbness, tingling, or weakness extending into the leg
-
Sciatica or lumbar radiculopathy
-
Spinal stenosis, which is narrowing of the spinal canal and may cause leg pain with standing or walking that improves with sitting or leaning forward
-
A spinal fracture, particularly in people with osteoporosis
-
Inflammatory arthritis affecting the spine
-
Infection
-
Cancer involving the spine
-
Other less common neurologic or musculoskeletal conditions
It is important to understand that many findings described as “abnormal” on an MRI are also commonly seen in people who do not have back pain. Disc bulges, arthritis, degeneration, and age-related wear are frequently present without causing symptoms.
An imaging report showing these changes does not necessarily mean that the spine is damaged, unstable, or fragile. The findings must be interpreted together with the patient’s symptoms and physical examination.
What Makes Back Pain More Likely?
Factors associated with a greater likelihood of developing back pain include:
-
Previous episodes of back pain
-
Obesity
-
Smoking
-
Heavy lifting or physically demanding work
-
Repetitive bending or twisting
-
A sedentary lifestyle
-
Poor physical conditioning
-
Diabetes
-
Depression or anxiety
-
High levels of stress
-
Sleep disturbance
-
Genetic factors
-
Age-related changes in the spine
Types of Back Pain
Back pain is often categorized according to how long the symptoms have been present:
-
Acute back pain: Less than six weeks
-
Subacute back pain: Six to twelve weeks
-
Chronic back pain: More than twelve weeks
Acute back pain improves relatively quickly for most people. Pain levels often decrease substantially during the first six weeks.
Chronic back pain may improve more gradually and can fluctuate over time. Many people experience periods of improvement followed by temporary flare-ups. A flare-up does not necessarily mean that new damage has occurred.
Warning Signs: When to Seek Care Promptly
Most back pain does not require emergency treatment. However, some symptoms may indicate a more serious condition.
Patients should seek prompt medical evaluation if back pain occurs with:
-
New difficulty urinating
-
Loss of bladder or bowel control
-
Numbness in the groin, inner thighs, or saddle area
-
Progressive or severe weakness in a leg or foot
-
Fever or a recent serious infection
-
Intravenous drug use
-
A weakened immune system
-
A significant fall, accident, or other injury
-
A minor fall in someone with osteoporosis, long-term steroid use, or advanced age
-
A history of cancer
-
Unexplained weight loss
-
Severe pain that repeatedly wakes the patient from sleep
-
Pain that continues to worsen despite appropriate care
New bladder or bowel dysfunction, saddle numbness, or rapidly progressive weakness may be signs of cauda equina syndrome, a spinal emergency requiring immediate evaluation.
Frequently Asked Questions:
Do I Need an X-Ray or MRI?
Most people with uncomplicated back pain do not need imaging right away.
Routine X-rays and MRIs during the first several weeks generally do not improve outcomes when warning signs are absent. Imaging may identify normal age-related findings that are not responsible for the patient’s pain and may lead to unnecessary testing or procedures.
Imaging may be appropriate when:
-
Warning signs are present
-
A fracture is suspected
-
Infection or cancer is a concern
-
There is severe or progressive weakness
-
Sciatica persists despite conservative treatment
-
An injection or surgery is being considered
-
The diagnosis remains unclear after a detailed evaluation
The decision to order imaging should be based on the history, physical examination, symptoms, and treatment plan rather than pain severity alone.
Treatments That May Not Help Acute Back Pain
Certain treatments are not routinely recommended for uncomplicated acute back pain.
These may include:
-
Prolonged bed rest
-
Routine opioid medication
-
Routine oral steroid treatment
-
Unnecessary imaging
-
Passive treatment without a plan to restore movement and function
Treatment should be individualized based on the patient’s diagnosis, medical history, examination, and response to prior care.
Treatment for Chronic Back Pain
For back pain lasting longer than twelve weeks, the most effective treatment plans usually emphasize active rehabilitation rather than relying exclusively on medications or passive procedures.

Medications for Chronic Back Pain
Medications are usually used as one part of a comprehensive plan.
Options may include:
-
NSAIDs
-
Duloxetine
-
Topical medications
-
Selected muscle relaxants
-
Other medications based on the specific diagnosis
Long-term opioid therapy is generally approached cautiously because the potential risks may outweigh the benefits for many patients.
Any medication plan should be individualized and monitored for effectiveness, side effects, safety, and functional improvement.
Psychological & Behavioral Treatment
Cognitive behavioral therapy, mindfulness-based stress reduction, and other pain coping strategies may improve pain and function.
These approaches do not imply that pain is imaginary. They teach practical skills for reducing the effect of pain on sleep, mood, movement, and daily activities.
Epidural Steroid Injections
An epidural steroid injection may provide modest short-term relief for severe or persistent leg pain.
The goal is often to reduce pain enough for the patient to participate more effectively in rehabilitation.
These injections do not reliably provide permanent relief and do not eliminate the underlying age-related changes in the spine.
Physical Therapy
Physical therapy can address weakness, limited mobility, poor body mechanics, reduced endurance, fear of movement, and difficulty performing daily activities.
Multidisciplinary Rehabilitation
Some patients benefit from a coordinated program involving medical care, physical rehabilitation, and behavioral support.
Surgery
Surgery may be considered when:
-
Leg pain remains severe despite conservative treatment
-
Symptoms, examination findings, and MRI results are consistent
-
There is progressive weakness
-
The patient has significant functional impairment
-
Cauda equina syndrome is suspected
Education and Self-Management
Understanding that pain can persist even when there is no ongoing tissue damage can reduce fear and improve confidence with movement.
Education may include pacing, activity modification, home exercises, flare-up management, sleep habits, and techniques for safely returning to work or recreation.
Complementary Treatments
Massage, acupuncture, spinal manipulation, and other hands-on treatments may be used as additional components of a broader treatment plan.

-
Review of medications and prior treatments
-
Determination of whether imaging, electrodiagnostic testing, physical therapy, injections, bracing, or specialty referral may be appropriate
What to Expect in your
First Visit?
During the first visit, the physician will review the history of the back pain, previous treatments, medications, imaging, and the ways in which the symptoms affect daily life.
A detailed musculoskeletal and neurologic examination will be performed. Additional testing will be ordered only when medically appropriate.
The visit will conclude with an individualized treatment plan that may include exercise, physical therapy, medications, bracing, injections, testing, or coordinated specialty care.
Frequently Asked Questions
Is back pain always caused by a damaged disc?
-
No. Most back pain cannot be traced to one damaged structure. Disc changes are common with aging and may be present in people who have no pain.
Should I rest until the pain is completely gone?
-
Usually not. Gentle movement and continued activity are generally more helpful than prolonged bed rest.
Does severe pain mean that something serious is wrong?
-
Not necessarily. Pain intensity alone does not reliably indicate the amount of structural damage. However, severe pain accompanied by weakness, bladder or bowel changes, fever, trauma, cancer history, or unexplained weight loss should be evaluated promptly.
When should I have an MRI?
-
An MRI may be appropriate when warning signs are present, neurologic symptoms are progressing, symptoms persist despite treatment, or an injection or surgery is being considered.
Can chronic back pain improve?
-
Yes. Chronic back pain often improves with consistent exercise, education, rehabilitation, healthy sleep, stress management, and an individualized treatment plan.
Will I need surgery?
-
Most people with back pain do not need surgery. Surgery is generally reserved for selected patients with a clearly identified condition, persistent symptoms, severe functional limitations, or progressive neurologic problems.
