Back Pain

Overview

Back pain is one of the most common reasons people seek orthopedic care.

Many patients arrive after following a familiar sequence: pain medication, a scan and then a discussion about injections or surgery.

At Nucellin Orthopedic Clinic in Hannam-dong, Seoul, we begin in a different place.

Dr. Kim personally evaluates each patient and can conduct the consultation in English.

Diagnosis begins with:

• Your symptoms
• Physical examination
• Neurologic findings
• Daily loading pattern
• Previous treatment and imaging

X-rays and MRI findings are then interpreted in that clinical context.

Pain is real, but the intensity of pain alone does not determine whether surgery is necessary.

Most episodes of back pain do not require an operation.

The first task is to identify what is actually generating the symptoms. The source may be:

• A disc
• Facet joint
• Nerve root
• Muscle
• Ligament
• Sacroiliac-region structure
• Surrounding soft tissue

The source is not always located exactly where the pain is felt.

This page explains how back pain is assessed, which non-surgical treatments may be considered and when urgent or surgical evaluation may be appropriate.

Symptoms

Back pain can appear in many different ways.

The location, timing and behaviour of the symptoms often provide more useful information than pain intensity alone.

• Sudden low back pain after lifting or an awkward movement: may be associated with muscle strain, joint irritation or disc-related pain.
• Difficulty bending forward: may occur with acute disc irritation, muscle guarding or severe pain inhibition.
• A deep ache after prolonged sitting: may be related to sustained spinal loading, reduced movement or disc and muscle sensitivity.
• Pain extending into the buttock or leg: may indicate nerve-root irritation, but it can also be referred from muscles, joints or other soft tissues.
• Tingling, numbness or electric pain in the leg: increases the possibility of nerve involvement and requires a neurologic examination.
• Morning stiffness that improves with movement: may occur with degenerative change, muscle stiffness or inflammatory conditions.
• Pain when standing or walking for an extended period: may be associated with facet joints, spinal stenosis, muscle fatigue or reduced load tolerance.
• Repeated episodes over several years: may indicate that the underlying movement, strength or loading pattern has not been adequately addressed.

Radiating pain does not automatically mean that a nerve is compressed.

True nerve-root symptoms are assessed by considering:

• Pain distribution
• Sensation
• Muscle strength
• Reflexes
• Nerve-tension testing

This distinction affects both treatment and the need for imaging.

Causes

Common causes of back pain include:

• Muscle and soft-tissue strain
• Disc irritation or disc herniation
• Facet-joint pain
• Sacroiliac-region pain
• Nerve-root irritation
• Age-related disc and joint degeneration
• Spinal stenosis
• Previous injury or surgery
• Repeated occupational or athletic loading

In younger patients, lifting injuries, sport, prolonged sitting and sudden changes in training volume are common contributors.

With increasing age, degenerative changes of the discs, facet joints and spinal canal become more common.

However, not every pain felt in the lower back originates from the spine itself.

The gluteal muscles, upper hamstring, hip, quadratus lumborum and other surrounding tissues can refer pain into the lower back, pelvis or leg.

In some patients, pressure on these structures reproduces symptoms that have previously been labelled as sciatica.

This does not mean that the original symptoms were imaginary.

It means that the assumed source of the pain may not have been correct.

The answer is not always a stronger spinal procedure.

Sometimes it is a more accurate treatment target.

Diagnosis

Diagnosis begins with a detailed history and a hands-on examination.

We consider questions such as:

• Where did the pain begin?
• Is it centred in the back, buttock or leg?
• Does it extend below the knee?
• Is there numbness, tingling or weakness?
• Which movements reproduce the pain?
• Is the pain worse with sitting, bending, standing or walking?
• Is there a history of injury, surgery, fever, cancer or osteoporosis?
• What does the back have to tolerate during work, travel, exercise and daily life?

The examination may include:

• Spinal range of motion
• Palpation of the spine and surrounding soft tissues
• Hip and pelvic assessment
• Muscle-strength testing
• Sensory and reflex examination
• Nerve-tension testing
• Walking and balance assessment
• Evaluation of movements that reproduce the symptoms

The aim is not simply to give the pain a familiar label.

It is to determine which structure or system is most likely responsible and whether there are signs of neurologic compromise or another serious condition.

Diagnosis and Imaging

X-ray

X-rays may be useful when there is concern about:

• Fracture
• Alignment
• Instability
• Advanced degeneration
• Previous surgery
• Certain structural conditions

However, an X-ray does not show discs, nerves or many soft-tissue structures in detail.

MRI

MRI is useful when it is likely to change the diagnosis or treatment plan.

It may be recommended when there is:

• Persistent or progressive leg pain
• Significant numbness or weakness
• Suspected disc herniation with neurologic findings
• Suspected spinal stenosis
• Concern about infection, tumour or fracture
• Persistent symptoms despite appropriate non-surgical treatment
• A need to plan surgery or another targeted procedure

MRI is not automatically required for every episode of back pain.

Disc bulges, degeneration and other structural changes are common in adults who have no pain.

The presence of an abnormality does not prove that it is the source of the patient’s symptoms.

The important question is not only:

“What does the MRI show?”

It is also:

“Does this finding explain the patient’s pain pattern, neurologic examination and functional limitations?”

The scan provides structural information.

The examination determines what that information means.

When MRI is medically appropriate, we can arrange imaging at a nearby radiology centre and review the results with you.

Musculoskeletal Ultrasound

Ultrasound does not replace MRI for evaluating discs, the spinal canal or nerve roots inside the spine.

However, it may be useful for assessing selected muscles, tendons, bursae and other soft tissues around the lower back, hip and pelvis.

It can also be used to guide certain injections accurately when the suspected pain source is visible and safely accessible with ultrasound.

What Your Scan Does and Does Not Tell You

A scan can show anatomy and structural change.

It cannot directly measure:

• Pain
• Muscle capacity
• Nervous-system sensitivity
• Daily load tolerance
• Functional adaptation

An abnormal scan can exist without symptoms.

Significant symptoms can also exist without a dramatic abnormality on imaging.

An image is one piece of evidence, not the entire diagnosis.

Understanding Radiating Leg Pain

Pain extending into the leg is commonly called sciatica, but not all radiating pain is true sciatica.

True lumbar radiculopathy usually involves irritation or compression of a spinal nerve root.

Symptoms may include:

• Pain following a recognisable nerve distribution
• Tingling or numbness
• Reduced muscle strength
• Changes in reflexes
• Pain reproduced by nerve-tension testing

Pain can also be referred into the buttock or thigh from:

• Facet joints
• Sacroiliac-region structures
• Gluteal muscles
• Hamstring origin
• Deep hip muscles
• Myofascial trigger points

These conditions may feel similar to nerve pain but require a different treatment approach.

This is why treatment should not be chosen from the MRI report alone.

Treatment Options

Treatment is introduced step by step and adjusted according to the diagnosis, severity of symptoms and response.

We begin with the least invasive option that can reasonably improve function and reduce symptoms.

Treatment response is judged by practical changes such as:

• Can the patient sit for longer?
• Is walking easier?
• Can the patient bend or stand with less difficulty?
• Is leg pain becoming less frequent?
• Is strength or sensation improving?
• Is the back tolerating more daily activity?

Some acute conditions may improve over several days or weeks.

Chronic pain, reduced strength and long-standing movement patterns may require a longer rehabilitation period.

The goal is not simply to suppress pain temporarily.

It is to restore the capacity of the spine and surrounding tissues to tolerate daily load.

Activity Modification and Rehabilitation

For most patients, the foundation of treatment is appropriate movement rather than prolonged rest.

Treatment may include:

• Temporary modification of painful activities
• Gradual return to walking and exercise
• Trunk and hip strengthening
• Improvement of movement control
• Advice regarding sitting and lifting
• Reduction of repeated occupational overload
• A structured home exercise programme

Long bed rest can lead to stiffness, muscle loss and greater sensitivity when activity is resumed.

However, “keep moving” does not mean forcing the body through severe pain.

The appropriate level and direction of movement depend on the diagnosis.

In an acute episode, some exercises or stretches may aggravate the irritated tissue.

Treatment should therefore be based on the individual pain pattern rather than a standard list of back exercises.

Medication and Symptom Control

Medication may be considered when appropriate to reduce pain and allow the patient to remain mobile.

The choice of medication depends on:

• The type and severity of pain
• Other medical conditions
• Current medications
• Allergy history
• Kidney, stomach, cardiovascular and bleeding risks

Medication can help control symptoms, but it does not replace examination, load modification or rehabilitation.

Targeted Image-Guided Treatment

Selected patients may benefit from an accurately targeted procedure when examination and imaging identify a specific pain-generating structure.

Depending on the diagnosis, treatment may be directed toward:

• Facet-joint-related structures
• Medial branch nerves
• Sacroiliac-region structures
• Painful muscles or fascial planes
• Selected peripheral nerves
• Soft tissues around the hip, pelvis or lower back

Ultrasound or fluoroscopic guidance may be used depending on the location and type of procedure.

A treatment should not be performed simply because an MRI shows degeneration.

The target should be supported by the symptoms, examination and imaging together.

The expected benefits, limitations and risks are discussed before treatment.

PDRN-Based Regenerative Injection Treatment

PDRN-based treatment may be considered for selected patients when the suspected pain source involves irritated soft tissue or a targeted periarticular or peripheral neural structure.

The purpose is to support symptom control and tissue recovery without relying on corticosteroid treatment.

It is not a universal treatment for back pain.

It cannot correct:

• Severe nerve compression
• Major instability
• Fracture
• Infection
• Tumour
• Advanced structural disease requiring surgery

Suitability is determined after examination and imaging review.

Activated PRF Treatment

Activated platelet-rich fibrin may be considered in carefully selected patients with chronic spinal or surrounding soft-tissue pain.

Activated PRF is prepared from the patient’s own blood and is intended to provide a sustained biologic environment around the treated area.

Its use may be considered for selected:

• Facet-related problems
• Ligamentous pain
• Tendon or muscle-related pain
• Surrounding soft-tissue problems
• Peripheral neural targets

The evidence for biologic injections in the spine remains less established than for many peripheral tendon and joint conditions.

Activated PRF should therefore not be presented as a routine cure for disc degeneration or nerve compression.

It cannot guarantee:

• Disc regeneration
• Permanent pain relief
• Reversal of nerve compression
• Prevention of future surgery

The decision to use it depends on:

• The suspected pain source
• Neurologic examination
• Imaging findings
• Previous treatment
• General health
• Functional goals
• A realistic discussion of the available evidence

Stem Cell-Based Treatment

Autologous bone marrow- or adipose-derived cell-based treatment may be considered for carefully selected patients with chronic degenerative musculoskeletal pain.

It is generally considered only when:

• The history and physical examination identify a plausible pain generator
• Neurologic assessment does not suggest progressive nerve damage
• Imaging supports the proposed treatment target
• Appropriate conservative treatment has not provided sufficient improvement
• The patient understands the limitations of current evidence

In the spine, stem cell-based treatment is not a routine first-line treatment for:

• Non-specific back pain
• Disc degeneration seen only on imaging
• Lumbar radiculopathy caused by significant nerve compression
• Severe spinal stenosis
• Major instability

It is not appropriate when symptoms are caused by:

• Progressive nerve damage
• Cauda equina syndrome
• Severe nerve-root compression requiring decompression
• Significant mechanical instability
• Fracture
• Infection
• Tumour
• Another condition requiring urgent or surgical treatment

Current clinical evidence for cell-based treatment in degenerative spinal conditions remains limited.

Some studies report improvement in pain and function, but reliable regeneration of a damaged lumbar disc has not been established.

Stem cell-based treatment cannot guarantee:

• Regeneration of a lumbar disc
• Restoration of normal disc height
• Permanent pain relief
• Reversal of nerve compression
• Prevention of future surgery
• Restoration of a young and normal spine

Suitability depends on:

• The suspected pain generator
• Neurologic findings
• Imaging results
• The stage and location of degeneration
• Previous treatment
• General health
• Functional goals
• Realistic expectations regarding the available evidence

The potential benefits, limitations, rehabilitation plan and alternative treatments are discussed before any procedure.

Shockwave Therapy

Shockwave therapy is not used to treat discs, the spinal cord or nerve roots inside the spinal canal.

It may be considered when examination suggests that pain is arising from chronic soft-tissue overload around the:

• Lower back
• Gluteal region
• Pelvis
• Upper hamstring
• Surrounding muscle and fascial chain

Focused shockwave may be directed toward a specific pain-generating soft-tissue area.

Radial shockwave may be applied across a broader overloaded muscle chain.

Shockwave therapy is most appropriate when the identified target is an accessible muscle, tendon, fascial or other soft-tissue structure rather than an internal spinal lesion.

Regenerative Physical Therapy

Regenerative physical therapy may combine:

• Clinical assessment
• Movement retraining
• Manual treatment
• Shockwave therapy
• High-intensity laser therapy
• Soft-tissue treatment
• Advice regarding posture and load
• Gradual functional retraining

The purpose is to improve tissue capacity and movement rather than relying on a procedure alone.

A Realistic View of Regenerative Treatment

Regenerative treatment is not a replacement for an accurate diagnosis.

No injection or cell-based treatment can reliably restore every degenerative disc to a young and normal state.

These treatments cannot reverse significant nerve or spinal-cord compression.

They also cannot guarantee that surgery will never be required.

Realistic goals may include:

• Reducing local irritation
• Improving pain and function
• Supporting rehabilitation
• Increasing tolerance for sitting, standing and walking
• Treating an identified soft-tissue or joint-related pain source
• Delaying more invasive treatment when medically reasonable

The expected benefit depends heavily on choosing the correct target.

A technically successful procedure performed on the wrong structure remains the wrong treatment.

When Surgery May Be Appropriate

Non-surgical treatment is not always the safest or most effective option.

A surgical opinion may be appropriate when there is:

• Progressive muscle weakness
• Foot drop
• Significant neurologic loss
• Cauda equina syndrome
• Severe nerve compression with persistent disabling symptoms
• Major spinal instability
• Fracture
• Infection
• Tumour
• Persistent pain and functional loss that have not responded to appropriate non-surgical treatment

A high pain score alone is not usually enough to determine the need for surgery.

The decision should be based on:

• Diagnosis
• Neurologic findings
• Imaging
• Functional limitations
• Response to previous treatment

When the indication is correct, surgery can be highly valuable.

The goal is not to avoid surgery at all costs.

It is to make sure that the indication is clear and the timing is appropriate.

Managing Back Pain Day to Day

Most backs recover through appropriately dosed movement, not prolonged avoidance.

• Keep walking when possible. Several short walks may be more manageable than one long session.
• Break up prolonged sitting. Change position and move regularly rather than searching for one perfect posture.
• Keep loads close to the body. Avoid twisting while lifting a heavy object.
• Spread demanding tasks across the day. Repeated loading while fatigued can aggravate symptoms.
• Do not repeatedly stretch into sharp pain. A painful direction may need to be temporarily reduced.
• Return to exercise gradually. The back needs time to adapt to increasing load.
• Pay attention to leg symptoms. Increasing numbness or weakness should not be treated as a normal exercise response.
• Avoid prolonged bed rest. Rest may be useful briefly during a severe flare, but extended inactivity can delay recovery.

A temporary flare-up does not always mean that new structural damage has occurred.

It may indicate that the current load exceeded the back’s present capacity.

If the same episode repeatedly returns, the useful question is not only:

“What is wrong with my back?”

It is also:

“What is my back being asked to tolerate every day that it is not yet prepared for?”

When to See a Doctor

Arrange an assessment if back pain:

• Continues for more than a few weeks
• Repeatedly returns
• Extends into the buttock or leg
• Is associated with numbness or tingling
• Limits walking, sitting, work or sleep
• Is progressively worsening
• Has not improved with sensible activity modification
• Occurs after a significant injury
• Is accompanied by unexplained general symptoms

Persistent leg symptoms deserve a neurologic examination rather than repeated pain medication alone.

When to Seek Urgent Medical Care

Go to an emergency department immediately if you develop:

• New loss of bladder or bowel control
• Inability to begin urination
• Loss of awareness of bladder filling
• Numbness around the groin, genitals, buttocks or inner thighs
• Rapidly progressive weakness in one or both legs
• New foot drop
• Severe back pain with fever or chills
• Back pain after major trauma
• Severe back pain with a history of cancer
• Back pain with unexplained weight loss
• Back pain with significant immune suppression
• Sudden severe pain in a patient with osteoporosis or prolonged steroid exposure

Loss of bladder or bowel control, saddle-area numbness and progressive leg weakness may indicate cauda equina syndrome or another serious neurologic condition.

These symptoms should not wait for a routine clinic appointment.

International Patients

International patients can consult directly with Dr. Kim in English.

You may bring or send previous X-rays, MRI images and medical reports.

Imaging is reviewed together with your symptoms, neurologic findings and physical examination rather than interpreted in isolation.

Nucellin Orthopedic Clinic does not have an on-site MRI scanner.

When MRI is medically appropriate, we can arrange imaging at a nearby radiology centre and review the results with you.

Same-day consultation and selected treatments may be possible when medically appropriate.

Bone marrow- or adipose-derived procedures generally require separate planning.

A written estimate is provided before treatment.

Information about insurance and payment is available on the Insurance & Payment page.

If you already have imaging, you may contact the clinic to arrange an evaluation.

Start with an informed medical opinion, not a procedure.
