What Is an Extruded Disc? Meaning, Symptoms and Care in KL

By Yama Zafer, D.C.

An extruded disc is a herniated disc that has progressed one stage further, its soft center expelled from the middle to the disc's outer edge. In a disc extrusion, the expelled center can travel above or below the disc. It can press on a nerve root, the nerve sac or the spinal cord. Pain from an extrusion often travels into a leg or an arm, yet some people I see in Kuala Lumpur notice only numbness or weakness.

Every extruded disc was a degenerated disc first, as my Back Pain to Leg Pain talk explains. Long sitting, bending, twisting and heavy lifting add the strain, over years or within days.

On its own, the MRI finding cannot tell where the pain starts, so after studying the images, I examine the nerves. In my view, an extrusion calls for a prompt assessment, though not automatically surgery; focused conservative care can be part of it. That care brings together physiotherapy, trigger point work, exercise once the spine is stable and chiropractic manipulation that is non-rotatory using the Activator instrument. Next come my short video, where the material travels, the urgent signs, daily loads and surgery.

Extruded Disc: Key Takeaways

QuestionShort answer
Is a disc extrusion serious?Yes. In my view, any disc that pushes past its normal confines becomes serious, and an extrusion is well past them. How serious depends on the tissue it reaches, judged on my scale from 0 to 10.
Does an extruded disc need surgery?Not always. Surgery is my last option, used only when focused conservative care, carried out properly, has not worked. A sequestered disc or an infection, however, can move it earlier. New numbness around the genitals or anus, new difficulty passing urine, or loss of bladder or bowel control needs urgent medical attention at a hospital emergency department straight away, within hours.
How is a protrusion different from an extrusion?A protrusion is still contained: its center has shifted outward, but no outer fiber has given way. An extrusion is three stages further on: the fibers have torn and the center has been forced to the disc's edge.
What do caudal and cephalad mean on a report?They name the direction the extruded material has traveled. Caudal means downward, below the disc; cephalad means upward, above it. My Back Pain to Leg Pain talk describes the caudal case as disc hanging down below.
What should be avoided with an extruded disc?Bending and twisting at the waist are out. Lifting is avoided, and an unavoidable lift stays under 2 kg. Hot packs, side bending, general stretching and yoga stay out. With back pain, a sitting break comes every 15 to 20 minutes.
Can an extruded disc return to normal?Not fully, in my view. A damaged disc draws in blood vessels as the body attempts repair, my Back Pain to Leg Pain talk explains. Yet “we're damaging it faster than our body can keep up.” Some damage always remains.
Is an extruded disc a slipped disc?Yes. My short video Why Extruded Discs Aren't As Bad As You Think calls extrusions large disc herniations, disc ruptures or slipped discs. Slipped disc is what most people say; extrusion is the stage word, and many MRI reports use it.
Extruded Disc Guide: Sections at a Glance

From Herniation to Disc Extrusion: Where This Stage Sits

An extruded disc comes near the end of disc damage, one stage before fragmentation. Bulge, herniation and slipped disc are words many people hear long before anyone explains which stage each one names. My stages run in this order: bulge, protrusion, prolapse, herniation (the same as a rupture), extrusion, then fragmentation. My Back Pain to Leg Pain talk names the step plainly: “After that is extrusion, which is progression.”

StageWhat has happenedStill part of the disc?
HerniationThe last outer fibers have torn: the disc has ruptured, and its center is no longer containedYes
ExtrusionThe center has been expelled from the middle to the disc's outer edge, at times traveling up or downYes, still joined to it
FragmentationPart of the center breaks off: partly at first, then fully, the sequestered discPartly, then not at all

Earlier on the same path come the bulge, the protrusion and the prolapse, each with its own guide. My Back Pain to Leg Pain talk also says “you can have an extrusion with a herniation, which is even more.” Both words can appear in one report, and in my stage order the extrusion is the further of the two.

The spinal column has 24 movable vertebrae resting on the sacrum and coccyx. Seven are in the neck, 12 in the upper and mid back and 5 in the lower back. The discs between them carry load, allow movement and spread body weight.

Each disc's outer rings, the annulus fibrosus, hold its soft center, the nucleus pulposus. I call the annulus “the largest ligament between the segments of the spine” in my Back Pain to Leg Pain talk. It joins one vertebra to the next. Thin cartilage end plates above and below let nutrients diffuse into the disc.

My video Bulging Disc vs Herniated Disc walks through the same order with a disc model. In it, I put this stage in one line: “an extrusion is a progression of a herniation.”

The video also explains why a tear on the side nearest the stomach matters less than one facing the spinal canal, where the nerves lie. The level of the damage, it shows, decides whether symptoms reach an arm or a leg. The video page breaks it into chapters, each with a short summary and an edited transcript.

Where to Arrange an Extruded Disc Assessment in Kuala Lumpur

Both CSC centers in Kuala Lumpur assess disc extrusions in the neck and the lower back. A first visit runs through these steps:

  1. The history form and any reports are read first, and MRI images, on CD or film, are studied before the examination.
  2. The examination checks movement and the nerve root in the material's path: its reflexes, skin feeling and muscle power.
  3. Orthopedic tests are chosen for the level involved. In the lower back they include the straight leg raise and Milgram's test. Patrick's test or pelvic compression lying on the side is added when a hip or sacroiliac joint may share the problem.
  4. When leg pain is severe, I leave out the tests that would provoke it: the straight leg raise, Milgram's test and the Valsalva maneuver. That last one means bearing down while holding the breath. Reflexes, skin feeling, muscle power and the MRI then carry the assessment, kept within what you can comfortably tolerate.
  5. A person with no scan yet is examined first; an MRI is requested only once the findings point to the disc or a joint.

The history carries much of the weight. In a study of 274 people with leg pain, the history alone predicted a compressed nerve root on MRI (Vroomen and colleagues, 2002). Adding the examination made that prediction only slightly better.

Where each center is and when it opens are listed on the CSC locations page. Bookings go through either center's contact page: Bukit Damansara or Bandar Sri Damansara. Either center can also be phoned directly:

Video: My 14-Second Definition of This Stage

My short video Why Extruded Discs Aren't As Bad As You Think defines the extrusion stage in 14 seconds. These are its words:

“An extruded disc is the progression of a ruptured or herniated disc where the nucleus pulposus is expelled from the center to the periphery of the spinal disc. These are large disc herniations, disc ruptures, or slipped discs in need of immediate attention.”

The periphery is the disc's outer edge. By immediate attention I mean a prompt assessment. It does not automatically mean surgery, and it can include focused conservative care.

Caudal, Cephalad or Central: Where Extruded Disc Material Travels

Extruded disc material can stay level with its disc or travel up or down behind the vertebrae. An MRI report names that direction with a few set words:

  • Caudal: downward, below the level of the disc. My Back Pain to Leg Pain talk describes “an extrusion with disc hanging down below.”
  • Cephalad, or cranial: upward, above the level of the disc.
  • Central or paracentral: toward the middle of the spinal canal, or just to one side of it, where a nerve root runs.
  • Foraminal: out to the side, into the bony gap, the foramen, where one nerve root exits between two vertebrae.
Three side views of a lower back disc between two vertebrae: extruded material pushed straight back at the disc level, hanging down below the disc (caudal) and moved up above it (cephalad), each still joined to the disc
Seen from the side: extruded material can stay level with its disc, hang down below it or move up above it.

A scan shows the shape as well as the direction. I read a soft, sagging shape as nucleus material, because the firm outer ring does not sag. My Back Pain to Leg Pain talk likens it to a sagging disc. The location words a report shares with earlier stages, such as subarticular, are explained in the location section of the disc protrusion guide.

Is Extruded Material Still Joined to Its Disc?

Yes, extruded material is still joined to its disc. When a piece breaks away, the disc has reached fragmentation, which takes two forms, both covered in the fragmented disc guide. I count the full form, the sequestered disc, among the severe cases. A partial one may still suit highly focused, precisely delivered care from an experienced clinician, after a thorough assessment finds no urgent sign.

Why Do Some Reports Call This Stage a Bulge?

Some reports call an extruded disc a bulge because a degenerated disc no longer shows the border between its center and outer ring. My Back Pain to Leg Pain talk notes that the radiologist then cannot document the stage and uses the word bulge. When an extruded disc patient asks me whether the disc bulge is serious, my answer is yes. By my definition, a disc that displaces the nerve sac or presses on a nerve is no longer a bulge.

Disc Extrusion Symptoms in the Neck and Lower Back

Pain is the most common complaint with a disc extrusion, felt in the spine, an arm or a leg. Yet the back or neck itself may not hurt at all. Some of the patients I describe in my Back Pain to Leg Pain talk notice nothing but weak legs. Others feel only numbness, tingling or burning in a limb.

Where those symptoms travel depends on which disc has extruded. In the lower back, I see extrusions most often at L4-L5, where most bending at the waist takes place, and next at L5-S1. In the neck, C5-C6 is the level I see extrude most often, with C4-C5 and C6-C7 also frequent. The L4-L5, L5-S1 and C5-C6 guides cover each of these levels.

Neck (Cervical) Extrusion

  • Neck stiffness or pain, sometimes spreading to the shoulders, upper back or shoulder blades.
  • Pain, tingling or numbness into the arm, hand or fingers.
  • Weakness in the shoulder, arm or hand.

Lower Back (Lumbar) Extrusion

  • Sciatica: pain spreading from the lower back or buttock into the hip, thigh and leg, often below the knee.
  • Tingling, burning or numbness in the leg or foot.
  • Weakness in the leg or foot.
  • New numbness around the genitals or anus, or new difficulty passing urine, which needs the urgent assessment described below.

Why Neck and Back Issues Sometimes Return

Even when symptoms improve, spine and joint issues can return. In many cases, the factors that load the spine, such as posture, movement and daily habits, were never fully addressed. I say it plainly in Sciatica vs Slipped Disc: “recurrent neck and back issues are common.” Once someone improves, the preventive work begins.

My video Why Neck & Back Issues Keep Coming Back looks at this question. In it, I share my three-step guide to why spine and joint issues recur and what is often overlooked along the way.

How the Damage Develops and Why It Hurts

A disc extrusion forms only after degeneration has weakened the disc. In my Back Pain to Leg Pain talk, extrusion is one of the stages I name that cannot occur “without having degeneration.” Long sitting, repeated bending, twisting at the waist and lifting load the weakened fibers. A sneeze or a cough can then be the last strain on a disc already damaged.

A damaged disc does prompt a repair attempt, with blood vessels and nerves growing into it. My Back Pain to Leg Pain talk explains why it falls short: “we're damaging it faster than our body can keep up.” In the same talk I add that the new nerves make a torn disc even more sensitive. The pace of the damage varies: “it can go rapidly or it can take years.”

Pain from an extrusion has more than one source. Once out, the material can cause it in three ways:

  • Pressure on a nerve root: the extruded material can press on or irritate a nearby nerve root, causing arm or leg symptoms.
  • Inflammation: disc material outside the disc triggers an inflammatory response that sensitizes the nerve, often more than the pressure alone.
  • Surrounding tissues: the joints, muscles and ligaments of the segment can also contribute.

Which Conditions Can Occur Alongside It?

Degenerative disc changes at the same or nearby levels, ligamentum flavum hypertrophy and facet hypertrophy can all occur alongside an extruded disc. In my experience, ligamentum flavum thickening is exceedingly common with an extruded disc, mild or moderate in nearly every case. The ligamentum flavum lines the back of the spinal canal, and when it thickens, the canal narrows. Facet hypertrophy is the arthritic enlargement of the facet joints, which link each vertebra to the next, and bone spurs can form with it.

I call these co-conditions: other problems that develop in parallel with a damaged disc. An extrusion is a late stage of disc damage, and in my experience it seldom comes without co-conditions.

Spondylolisthesis, where one vertebra slips forward on the one below, can be among them. So can spondylosis, the wear of the spine's joints and discs, and scoliosis, a sideways curve of the spine. The MRI and my examination show which are present, and the plan takes each one into account.

How Serious Is a Disc Extrusion?

A disc extrusion is serious, and how serious depends on what its material reaches. I judge that on a scale from 0 to 10: 0 is not serious at all, and 10 is life-altering and critical. A disc that displaces the nerve sac or touches a nerve already rates 3 to 5. Nerve findings, not the size on the scan, decide how urgent an extrusion is.

An extrusion can exist with no back pain at all, as my Back Pain to Leg Pain talk explains, yet such cases are uncommon. A 1994 MRI study looked at 98 people without back pain. A bulge showed in 52 percent and a protrusion in 27 percent, but an extrusion in only 1 percent (Jensen and colleagues, 1994).

Signs That Need Prompt Assessment

If leg pain from an extruded lumbar disc is accompanied by new or worsening numbness around your genitals, between your genitals and anus, or around your anus, get urgent medical attention: a thorough assessment at a hospital emergency department straight away, within hours. New difficulty passing urine needs the same urgent assessment, even when bladder and bowel control have not changed, and so does any loss of that control. These symptoms can arise for several reasons. Some may call for an invasive procedure, but the purpose of assessment is to identify the cause and appropriate care; it does not mean surgery is automatically required.

Leg weakness that keeps getting worse should not be ignored. It calls for a careful assessment by a competent provider, and conservative care can continue only while the weakness itself is improving. An arm that keeps weakening, unsteady walking or poorer coordination, and nerve symptoms that worsen quickly each call for that same assessment.

In the neck, extruded material can reach as far as the spinal cord. Pressing there, it can bring the signs I list in my Back Pain to Leg Pain talk:

  • Symptoms in the arms and hands.
  • Symptoms reaching down into the legs.
  • Weakness.
  • Not being able to stand or walk.
  • Disturbed digestion.
  • Palpitations of the heart.
  • Trouble breathing.

Any one of these, on its own, needs a prompt medical assessment. They do not have to appear together.

Daily Habits I Ask for With a Damaged Disc

Between visits, what a person does all day shapes how an extruded disc behaves. My Back Pain to Leg Pain talk puts the core of it in three commands: “Do not bend, do not twist. Do not lift and carry in these postures.” Care has a fairer chance when what spares the disc goes up and what loads it comes down:

  • Sitting: with back pain, a break comes every 15 to 20 minutes. Stand up, walk and move for 30 seconds to a minute. My Desk Posture Mistakes video shows the desk set-up between breaks. Anyone without a back problem takes a break every 30 to 40 minutes. When sitting cannot be avoided, a back support goes behind the lower back.
  • Driving: with acute, intense back pain, I advise a stop after about 15 minutes and never more than 20 to 30 minutes at the wheel. Each break, pulled over somewhere safe, is spent walking a little.
  • Bending, twisting and lifting: no bending or twisting at the waist, and lifting only when unavoidable, never over 2 kg. Bending backward is left out too, since it pinches the disc fibers and the nerves leaving the spine.
  • Yoga, stretching and sport: with an extruded disc, yoga must be avoided at every stage. Stretching of every kind waits through the early stage, and even afterward general stretching and side bending stay off the list. Side bending “can increase the herniation there”, as my Back Pain to Leg Pain talk warns. No deadlifts or free weights; walking in water replaces swimming laps.
  • Ice, not hot packs: my Back Pain to Leg Pain talk rules out hot packs on a damaged disc. Ice wrapped in a cloth goes on two or three times a day, 10 to 15 minutes each time, at least two hours apart.
  • Sleep: never under six hours, as I set out in Neck and Back Self-Help Tips. My Back Pain to Leg Pain talk asks for seven to eight unbroken hours. Side-lying comes first, the right side ahead of the left, with the spine forming one line. On the back, a bolster sits beneath the knees.
  • Movement: walking is encouraged, and positions change often through the day. My reason, from Sciatica vs Slipped Disc, fits in three words: “Mobility is good.”

Pain that follows an activity, during it or within the next 72 hours, means that activity stops for now. In my experience, inflammation can take up to 72 hours to show.

Where Surgery Fits and Why It Comes Last

Spine surgery should always be the last option, and that holds for an extruded disc. In Sciatica vs Slipped Disc, I say it this way: “Surgery should be the last option. Exhaust conservative route.” For me, exhausting that route means a fair trial of focused conservative care, done well.

Surgery becomes an option once that care has not worked, or earlier when the case is severe. Severe cases that move surgery up include a sequestered disc, an infection and the urgent signs above. Nerve loss that keeps getting worse also needs a prompt assessment, which can change the plan.

The usual operation for a disc is a microdiscectomy, in which a surgeon removes the extruded material through a small incision. This and the other disc operations, with their risks, are covered in Spine Surgery Risks & Non-Invasive Alternatives. That guide also sets out the options short of surgery.

Steroid injections are another option some people are offered. In Sciatica vs Slipped Disc, I list them among the steps I would not take: “I wouldn't recommend any of those.”

How Disc Damage Reaches the Legs: My Full Talk

Back or neck symptoms that travel into an arm, the buttock, a thigh or a leg often come from changes in a spinal disc. Recorded before a live audience, my Back Pain to Leg Pain talk runs 1 hour 47 minutes and traces that path from start to finish. It explains how discs work, how damage builds over time and why some positions raise the pressure inside them. It also covers spinal anatomy, the disc's structure and how a nerve becomes irritated once disc material moves past its normal borders.

Key Moments for an Extruded Disc

  • 26:21 Repair attempts in a damaged disc, outpaced by the damage
  • 30:24 An extrusion with a herniation, then fragmentation
  • 31:46 No disc damage without degeneration
  • 33:14 The stage order, from the bulge to extrusion
  • 34:41 Damage can move rapidly or take years
  • 36:11 What pressure on the spinal cord can bring
  • 47:12 Weak legs with no back pain
  • 1:01:57 An extrusion with disc material hanging down below
  • 1:08:34 Why side bending is left out

Beyond the disc stages, the talk covers posture, sleep, disc hydration, movement and lifestyle. The talk also shows why symptoms differ from person to person. It explains why careful movement, posture and rehabilitation come before surgery in all but severe cases. Several of the daily habits above come from it.

The chapters of this talk, each with a short summary, are on the Back Pain to Leg Pain video page.

How a Disc Extrusion Is Managed at CSC

Conservative care, as I use the term for a disc extrusion, always means focused care. It starts from the MRI images and my own examination and is aimed at whatever causes they document, across the whole lower back or neck. It must do no harm, and routine treatment does not count. There are many forms of conservative care that I consider useless.

Four conditions guide that care: an accurate diagnosis and a plan that fits the findings. Delivery has the fewest flaws possible, and the person's posture, habits and daily activity change with it.

At CSC, chiropractors and physiotherapists share a single plan. My video Is Chiropractic Safe? 13 Questions Answered puts it plainly: “Don't choose between one or the other. Choose both.” With an extruded disc, the plan can include:

  • Chiropractic manipulation that is non-rotatory using the Activator instrument. Where the case suits them, SOT blocking, which rests the pelvis on angled blocks, or the Thompson technique, on a drop table, is added. None of the three twists the spine.
  • Flexion-distraction, on a table that flexes the lower back while gently separating the vertebrae.
  • Spinal decompression in selected cases, used alongside exercise rather than on its own; the evidence for decompression is limited. Sessions follow NSD Therapy® methods and protocols.
  • Physiotherapy and a graded exercise program, progressed as the nerve settles. Exercise waits until the spine is stable and ready, usually two to six weeks into care. While the disc is acutely inflamed, the wait is at least three weeks. Kegel exercises for the pelvic floor can start at once.
  • Trigger point and myofascial work on the muscles that guard the affected level.
  • High-intensity laser therapy, kept mildly warm and never hot, as my Back Pain to Leg Pain talk insists.
  • Cold therapy on the QMD, a machine with both cold and heat settings. Its heat setting is not used on a spine with a disc or facet joint problem.
  • Advice on sitting, lifting and activity, as in the daily habits above.

In Is Chiropractic Safe? 13 Questions Answered, I warn: when a disc is compressing a nerve, no one should “aggressively rotate and manipulate your spine”. No twisting or cracking is used on an extruded disc at any point.

Possible effects and risks are explained at the first visit, before care begins. Care is kept within what you can comfortably tolerate. Discomfort during care means it is being done too aggressively, so tell the clinician at once.

Progress is judged by the nerve examination, leg or arm symptoms and function. Each review repeats the tests from the first visit and records a pain score and the person's own feedback. My two checkpoints appear in Is Chiropractic Safe? 13 Questions Answered: without improvement by the fifth session, the case is reassessed. If the tenth passes with none, the person and their chiropractor decide whether care goes on.

Active care for an extruded disc continues until what I call MMI, maximum medical improvement. I judge it reached when two or three further weeks of care no longer change the retested findings. Getting there means caring for every damaged part involved: the joints, ligaments and muscles around the disc, not the disc alone. Care then becomes as-needed, with prevention, daily-habit advice and home exercises.

The chiropractic fees in Kuala Lumpur and physiotherapy price in Kuala Lumpur pages give the cost of a single visit. The fee for a plan is explained and agreed before care begins.

Alongside extruded discs, you may also want to read about slipped discs, prolapsed discs, fragmented discs (partial or sequestered), and disc protrusions.

Care and Videos

Common Questions About an Extruded Disc

These eight answers take up surgery, safe care and daily life with an extruded disc. Each one draws on my videos, my written answers or my clinical experience.

Does a disc extrusion always require surgery?

No, a disc extrusion does not always require surgery. My short video Why Extruded Discs Aren't As Bad As You Think calls extrusions large herniations in need of immediate attention. In my view, that means a prompt assessment, and it does not automatically mean surgery.

Surgery comes into it when focused conservative care, done properly, has not worked, though a sequestered disc or an infection can bring it earlier. New numbness around the genitals or anus, new difficulty passing urine, or loss of bladder or bowel control needs urgent medical attention at a hospital emergency department straight away, within hours.

Is an extruded disc worse than a herniation?

Yes, in my stage order an extruded disc is one step past a herniated disc. In a herniation, the last outer fibers have torn and the center is no longer contained. In an extrusion, that center has been expelled all the way to the disc's outer edge. How serious either one is still depends on the tissue it reaches.

What is extruded disc material?

Extruded disc material is the soft center of the disc, the nucleus pulposus, after it has been forced out to the disc's edge or beyond. It is still joined to the disc; a piece that breaks away is a fragment.

My Back Pain to Leg Pain talk describes it on a scan as soft and sagging, unlike the firm outer ring. That contrast is how the two can be told apart on the images.

Can a disc extrusion happen in the neck?

Yes, a disc extrusion can happen in the neck as well as the lower back. In the neck, symptoms tend to reach the shoulder, arm, hand or fingers, with numbness, tingling or weakness.

An extrusion that reaches the spinal cord can affect the arms and hands and carry symptoms down to the legs. The cord signs in my Back Pain to Leg Pain talk also include weakness, trouble standing or walking, upset digestion, palpitations and difficulty breathing. Any single one calls for a prompt medical assessment.

No one should crack or yank a neck with a disc extrusion. In Neck Cracks Are Dangerous, I warn that such force can turn “a mild disc bulge” into “a severe disc herniation”.

Is chiropractic care safe with an extruded disc?

In my view, the only kind to consider is non-rotatory chiropractic care, with no twisting or cracking. In Is Chiropractic Safe? 13 Questions Answered, my examples of care without twisting include the Thompson technique, flexion-distraction, the SOT method and the Activator instrument. For a disc that is pressing on a nerve, I warn there against aggressive rotation and manipulation.

At CSC, that means chiropractic manipulation that is non-rotatory using the Activator instrument. Possible effects and risks are explained before care begins.

Can I sit or drive with a disc extrusion?

Yes, within limits: an extruded disc allows short spells of sitting and driving. With back pain, I ask for a sitting break every 15 to 20 minutes.

With acute, intense back pain, I keep drives to about 15 minutes, with 20 to 30 minutes as the outer limit. Each stop is made where it is safe, with a short walk. Once the acute phase has passed, the interval grows to 45 to 60 minutes, and a calf stretch joins the walk. A long road trip is better postponed, or taken in the front passenger seat, reclined.

When can exercise start with an extruded disc?

Exercise with an extruded disc waits until the spine is stable and ready. My short video calls extrusions large herniations, and for a herniated disc I begin exercise after about two to six weeks of care. With an acutely inflamed disc and acute pain, the wait is at least three weeks. Until then, care is aimed at the tissues around the disc.

The first exercises are simple: squats with the back against a wall and core canister breathing for the deep trunk muscles. Kegel exercises for the pelvic floor need no such wait. In Neck and Back Self-Help Tips, I ask my patients to begin them right away, since anyone with a lower back problem needs them. Buttock contractions and side-lying leg raises can begin early as well. Free weights and deadlifts stay out.

Can a disc extrusion get worse over time?

Yes, a disc extrusion can get worse. In Why Spinal Discs Get Damaged, I call disc damage “a progressive condition”. Beyond extrusion lies fragmentation, and its full form, the sequestered disc, is among the severe cases.

How fast it moves depends largely on the loads of each day. Hours of sitting, and bending, twisting or lifting, drive the damage forward. Breaks from the chair, regular walks and a full night's sleep take some of that load off the disc. Leg symptoms commonly settle sooner than the back, yet in my view the damage itself remains.

How to Read This Guide

Every view on this page is my own. When a view comes from a video or talk of mine, I name it. Other views draw on my written answers and clinical experience; the studies cited did not assess care at CSC. This guide covers extruded discs in general; judging your own disc takes an examination. The three reviews in the list on exercise and manual therapy (Hayden and colleagues, 2005; Bronfort and colleagues, 2010; van Middelkoop and colleagues, 2011) looked at back pain in general, not at extruded discs.
