Welcome to herniated disc recovery!
Herniated Disc Recovery – Our Mission
Our goal is to provide you with information on herniated disc recovery and information pertaining to herniated disc causes, herniated disc symptoms, specific disc herniation’s, treatment options, and further research is included in our website. We also may list other
so that you will have a easier time ruling out your back injury if you’re still trying to diagnose exactly what injury you are suffering from. Please read our disclaimer at the bottom of the page.
Herniated Disc Recovery – What is a herniated disc?
The bones (vertebrae) that form the spine in your back are cushioned by small, spongy discs. When these discs are healthy, they act as shock absorbers for the spine and keep the spine flexible. But when a disc is damaged, it may bulge or break open. This is called a herniated disc.
The backbone is grouped into five areas. The cervical or neck make up C1-C7 discs. The thoracic or middle back make up T1-T12 discs. The lumbar or lower back make up the L1-L5 discs. The last 2 areas are the Sacral and Coccyx. The most common herniated disc is the T5-S1 disc. Because this is the last disc and bears the most you can see how it is the most injury prone and herniated disc recovery will take a bit longer.

What Causes Herniated Disc Symptoms?
When the material of a herniated disc pushes upon a nerve, such as the sciatic nerve, it causes radicular pain that can be felt wherever the nerve travels. For instance, in a
the sciatic nerve is pinched by the material of a herniated disc. Because the sciatic nerve runs from the lower back and into the legs, a patient will feel radicular pain such as tingling and numbness down into the legs. The pain may vary from very little to severe. And this is what causes herniated disc symptoms. This same rule will apply to herniations anywhere along the spinal column.
Herniated Disc Recovery Time
About half of those diagnosed with a herniated disc will recover around a months time. This, however, is only because over a period of time inflammation will settle. The majority of us are looking towards a long herniated disc recovery of six months. The good news is that only about ten percent will need surgery and studies have shown that in a 5-10 period time frame there is very little difference in those that opted for surgery and those who didn’t.

Spinal disc herniation, also known as a slipped disc, is a
condition affecting the
in which a tear in the outer, fibrous ring of an
allows the soft, central portion to bulge out beyond the damaged outer rings. Disc
is usually due to age-related degeneration of the anulus fibrosus, although , lifting , or straining have been implicated. Tears are almost always postero-lateral in nature owing to the presence of the
in the spinal canal. This tear in the disc ring may result in the release of inflammatory chemical mediators, which may directly cause severe pain, even in the absence of nerve root compression.
Disc herniations are normally a further development of a previously existing disc "protrusion", a condition in which the outermost layers of the fibrous ring are still intact, but can bulge when the disc is under pressure. In contrast to a herniation, none of the central portion escapes beyond the outer layers. Most minor herniations heal within several weeks. Anti-inflammatory treatments for pain associated with disc herniation, protrusion, bulge, or disc tear are generally effective. Severe herniations may not heal of their own accord and may require surgery. The condition is widely referred to as a slipped disc, but this term is not medically accurate as the spinal discs are firmly attached between the vertebrae and cannot "slip".

Some of the terms commonly used to describe the condition include herniated disc, prolapsed disc, ruptured disc and slipped disc. Other phenomena that are closely related include disc protrusion, pinched nerves, , disc disease, disc degeneration, , and black disc. The popular term slipped disc is a misnomer, as the intervertebral discs are tightly sandwiched between two
to which they are attached, and cannot actually "slip", or even get out of place. The disc is actually grown together with the adjacent vertebrae and can be squeezed, stretched and twisted, all in small degrees. It can also be torn, ripped, herniated, and degenerated, but it cannot "slip". Some authors consider that the term "slipped disc" is harmful, as it leads to an incorrect idea of what has occurred and thus of the likely outcome. However, during growth, one vertebral body can slip relative to an adjacent vertebral body. This congenital deformity is called .
Symptoms of a herniated disc can vary depending on the location of the herniation and the types of soft tissue that become involved. They can range from little or no pain if the disc is the only tissue injured, to severe and unrelenting neck or
that will radiate into the regions served by affected nerve roots that are irritated or impinged by the herniated material. Often, herniated discs are not diagnosed immediately, as the patients come with undefined pains in the thighs, knees, or feet. Other symptoms may include sensory changes such as numbness, tingling, muscular weakness, paralysis, , and affection of reflexes. If the herniated disc is in the lumbar region the patient may also experience
due to irritation of one of the nerve roots of the . Unlike a pulsating pain or pain that comes and goes, which can be caused by muscle spasm, pain from a herniated disc is usually continuous or at least is continuous in a specific position of the body. It is possible to have a herniated disc without any pain or noticeable symptoms, depending on its location. If the extruded nucleus pulposus material doesn't press on soft tissues or nerves, it may not cause any symptoms. A small-sample study examining the cervical spine in symptom-free volunteers has found focal disc protrusions in 50% of participants, which suggests that a considerable part of the population can have focal herniated discs in their cervical region that do not cause noticeable symptoms.
A prolapsed disc in the lumbar spine can cause radiating nerve pain. This type of pain is usually felt in the lower extremities or groin area. Radiating nerve pain caused by a prolapsed disc can also cause bowel and bladder incontinence.
Typically, symptoms are experienced only on one side of the body. If the prolapse is very large and presses on the nerves within the spinal column or the , both sides of the body may be affected, often with serious consequences. Compression of the cauda equina can cause permanent nerve damage or paralysis. The nerve damage can result in loss of bowel and bladder control as well as sexual dysfunction. This disorder is called .
Other complications include .
Most authors favor degeneration of the intervertebral disc as the major cause of spinal disc herniation and cite trauma as a low cause. Disc degeneration occurs both with
and aging. With degeneration the contents of the disc, the
and , are exposed to altered loads. Specifically, the nucleus becomes fibrous and stiff and less able to bear load. The load is transferred to the anulus which, if it fails to bear the increased load, can lead to the development of fissures. If the fissures reach the periphery of the anulus, the nuclear material can pass through as a disc herniation.
Disc herniations can result from general , such as when performing jobs that require constant sitting and
or driving (). However, herniations often result from jobs that require lifting.[] Professional athletes, especially those playing , are prone to disc herniations. Minor back pain and chronic back tiredness are indicators of general wear and tear that make one susceptible to herniation on the occurrence of a traumatic event, such as bending to pick up a pencil or falling.[] When the spine is straight, such as in standing or lying down, internal pressure is equalized on all parts of the discs. While sitting or bending to lift, internal pressure on a disc can move from 17
(lying down) to over 300 psi (lifting with a rounded back).[]. Herniation of the contents of the disc into the spinal canal often occurs when the anterior side (stomach side) of the disc is compressed while sitting or bending forward, and the contents (nucleus pulposus) get pressed against the tightly stretched and thinned membrane (anulus fibrosus) on the posterior side (back side) of the disc. The combination of membrane thinning from stretching and increased internal pressure (200 to 300 psi) results in the rupture of the confining membrane. The jelly-like contents of the disc then move into the spinal canal, pressing against the spinal nerves, which may produce intense and potentially disabling pain and other symptoms.[] There is also a strong genetic component. Mutation in genes coding for proteins involved in the regulation of the extracellular matrix, such as
and , has been demonstrated to contribute to lumbar disc herniation.
There is now recognition of the importance of “chemical radiculitis” in the generation of . A primary focus of surgery is to remove “pressure” or reduce mechanical compression on a neural element: either the , or a . But it is increasingly recognized that back pain, rather than being solely due to compression, may also be due to chemical inflammation. There is evidence that points to a specific inflammatory mediator of this pain. This inflammatory molecule, called
(TNF), is released not only by the herniated disc, but also in cases of disc tear (annular tear), by facet joints, and in . In addition to causing pain and inflammation,
may also contribute to disc degeneration.
The majority of spinal disc herniation cases occur in
(95% in L4-L5 or L5-S1). The second most common site is the
(C5-C6, C6-C7). The
accounts for only 0.15% to 4.0% of cases. Herniations usually occur posterolaterally, where the anulus fibrosus is relatively thin and is not reinforced by the posterior or anterior longitudinal ligament. In the cervical spinal cord, a symptomatic posterolateral herniation between two vertebrae will impinge on the nerve which exits the spinal canal between those two vertebrae on that side. So for example, a right posterolateral herniation of the disc between vertebrae C5 and C6 will impinge on the right C6 spinal nerve. The rest of the spinal cord, however, is oriented differently, so a symptomatic posterolateral herniation between two vertebrae will actually impinge on the nerve exiting at the next intervertebral foramen down. So for example, a herniation of the disc between the L5 and S1 vertebrae will impinge on the S1 spinal nerve, which exits between the S1 and S2 vertebrae.
Cervical disc herniations occur in the neck, most often between the fifth & sixth (C5/6) and the sixth and seventh (C6/7) cervical vertebral bodies. Symptoms
can affect the back of the skull, the neck, shoulder girdle, scapula, arm, and hand. The nerves of the
can be affected.
Herniated lumbar disc.
disc herniations occur in the lower back, most often between the fourth and fifth lumbar vertebral bodies or between the fifth and the . Symptoms can affect the lower back, , ,
(via the ), and may radiate into the foot and/or . The
is the most commonly affected nerve, causing symptoms of . The
can also be affected and cause the patient to experience a numb, tingling feeling throughout one or both legs and even feet or even a burning feeling in the hips and legs.
Intradural disc herniation is a rare form of disc herniation with an incidence of 0.2-2.2%. Preoperative imaging can be helpful, but intraoperative findings are required to confirm.
Diagnosis is made by a practitioner based on the history, symptoms, and . At some point in the evaluation, tests may be performed to confirm or rule out other causes of symptoms such as , degeneration, ,
and space-occupying , as well as to evaluate the efficacy of potential treatment options.
Main article:
may be positive, as t however, it has high sensitivity. Thus the finding of a negative SLR sign is important in helping to "rule out" the possibility of a lower lumbar disc herniation. A variation is to lift the leg while the patient is sitting. However, this reduces the sensitivity of the test.
: Although traditional plain X-rays are limited in their ability to image soft tissues such as discs, muscles, and nerves, they are still used to confirm or exclude other possibilities such as tumors, infections, fractures, etc. In spite of these limitations, X-ray can still play a relatively inexpensive role in confirming the suspicion of the presence of a herniated disc. If a suspicion is thus strengthened, other methods may be used to provide final confirmation.
scan (CT or CAT scan): A diagnostic image created after a computer reads x-rays. It can show the shape and size of the spinal canal, its contents, and the structures around it, including soft tissues. However, visual confirmation of a disc herniation can be difficult with a CT.
(MRI): A diagnostic test that produces three-dimensional images of body structures using powerful magnets and computer technology. It can show the spinal cord, nerve roots, and surrounding areas, as well as enlargement, degeneration, and tumors. It shows soft tissues even better than CAT scans. An MRI performed with a high magnetic field strength usually provides the most conclusive evidence for diagnosis of a disc herniation. T2-weighted images allow for clear visualization of protruded disc material in the spinal canal.
: An x-ray of the spinal canal following injection of a contrast material into the surrounding cerebrospinal fluid spaces. By revealing displacement of the contrast material, it can show the presence of structures that can cause pressure on the spinal cord or nerves, such as herniated discs, tumors, or . Because it involves the injection of foreign substances, MRI scans are now preferred for most patients. Myelograms still provide excellent outlines of space-occupying lesions, especially when combined with CT scanning (CT myelography).
(EMG/NCS): These tests measure the electrical impulse along nerve roots, peripheral nerves, and muscle tissue. This will indicate whether there is ongoing nerve damage, if the nerves are in a state of healing from a past injury, or whether there is another site of nerve compression. EMG/NCS studies are typically used to pinpoint the sources of nerve dysfunction distal to the spine.
The presence and severity of
can be evaluated by means of
(TMS), a neurophysiological method that allows the measurement of the time required for a neural impulse to cross the pyramidal tracts, starting from the cerebral cortex and ending at the anterior horn cells of the cervical, thoracic or lumbar spinal cord. This measurement is called Central Conduction Time (CCT). TMS can aid physicians to:
determine whether myelopathy exists
identify the level of the spinal cord where myelopathy is located. This is especially useful in cases where more that two lesions may be responsible for the clinical symptoms and signs, such as in patients with two or more cervical disc hernias
follow-up the progression of myelopathy in time, for example before and after cervical spine surgery
TMS can also help in the differential diagnosis of different causes of pyramidal tract damage.

include , poor coordination, muscle burning and loss of the transverse abdominal brace. Individuals who engage in
place their bodies under heavy stress. Swimming is a common tool used in strength training. The usage of lumbarsacral support belts may restrict movement at the spine and support the back during lifting.
In the majority of cases, spinal disc herniation doesn't require surgery, and a study on , which can be caused by spinal disc herniation, found that "after 12 weeks, 73% of people showed reasonable to major improvement without surgery." The study, however, did not determine the number of individuals in the group that had sciatica caused by disc herniation.
Initial treatment usually consists of non-steroidal anti-inflammatory pain medication (), but the long-term use of NSAIDs for people with persistent back pain is complicated by their possible cardiovascular and gastrointestinal toxicity.
corticosteroid injections provide a slight and questionable short-term improvement in those with sciatica but are of no long term benefit. Complications occur in 0 to 17% of cases when performed on the neck and most are minor.
Non-surgical methods of treatment are usually attempted first, leaving surgery as a last resort. Pain medications are often prescribed as the first attempt to alleviate the acute pain and allow the patient to begin exercising and stretching. There are a variety of other non-surgical methods used in attempts to relieve the condition after it has occurred, often in combination with pain killers. They are either considered , , relatively contraindicated, or inconclusive based on the safety profile of their

: Moderate quality evidence suggests that spinal manipulation is more effective than placebo for the treatment of acute (less than 3 months duration) lumbar disc herniation and acute sciatica. The same study also found "low to very low" evidence for its usefulness in treating chronic lumbar symptoms (more than 3 months) and "The quality of evidence for ... cervical spine–related extremity symptoms of any duration is low or very low". A 2006 review of published research stated that spinal manipulation is likely to be safe when used by appropriately trained practitioners," and research currently suggests that spinal manipulation is safe for the treatment of disc-related pain.

A review of

Surgery may be useful in those with a herniated disc that is causing significant pain radiating into the leg, significant leg weakness, bladder problems, or loss of bowel control.

The presence of

concluded that "limited evidence is now available to support some aspects of surgical practice".
Disc herniation can occur in any disc in the spine, but the two most common forms are lumbar disc herniation and cervical disc herniation. The former is the most common, causing lower back pain () and often leg pain as well, in which case it is commonly referred to as . Lumbar disc herniation occurs 15 times more often than cervical (neck) disc herniation, and it is one of the most common causes of lower back pain. The cervical discs are affected 8% of the time and the upper-to-mid-back (thoracic) discs only 1 - 2% of the time.
The following locations have no discs and are therefore exempt from the risk of disc herniation: the upper two cervical intervertebral spaces, the , and the . Most disc herniations occur when a person is in their thirties or forties when the nucleus pulposus is still a gelatin-like substance. With age the nucleus pulposus changes ("dries out") and the risk of herniation is greatly reduced. After age 50 or 60,
