A slipped disc, also called a herniated or prolapsed disc, happens when the soft cushion between the bones of the spine pushes out of place and presses on nearby nerves. It can cause anything from mild stiffness to severe pain, numbness, or weakness that radiates down an arm or leg.

Read this guide to understand slipped disc causes, symptoms, MRI findings, diagnosis, and treatment options.
The spine is made up of bones called vertebrae, separated by soft, gel-like discs that act as cushions and allow flexibility. Each disc has a tough outer layer and a softer inner core. A slipped disc occurs when the inner core pushes through a weakened or torn part of the outer layer, bulging or herniating outward.
This can happen anywhere along the spine, but it is most common in the lower back (lumbar spine) and, less often, in the neck (cervical spine). Depending on how far the disc material pushes out, the condition may be described as a bulge, protrusion, extrusion, or sequestration.
A slipped disc usually develops gradually, although it can also happen suddenly.
As people age, the discs lose some of their water content and become less flexible, making them more prone to tearing or herniating even with minor strain. This natural degeneration is one of the most common contributing factors.
Repeated bending, twisting, or lifting, especially with poor technique, can gradually weaken the disc's outer layer over time.
A fall, road accident, or lifting a heavy object incorrectly can cause a disc to herniate suddenly.
Prolonged sitting with poor posture can increase pressure on the spinal discs, particularly in the lower back.
Carrying extra weight places additional stress on the discs in the lower spine.
Some people may be more prone to disc problems because of inherited differences in disc structure or strength.
Certain factors can increase the likelihood of developing a slipped disc:
However, a slipped disc can also occur in people without any obvious risk factors.
Symptoms depend on the location of the herniated disc and whether it is pressing on a nearby nerve.
Common symptoms include:
A slipped disc in the lower back often causes sciatica, which is pain that travels from the lower back through the buttock and down the leg. You can read more in our guide on sciatica causes, symptoms, and MRI diagnosis. A slipped disc in the neck may instead cause pain, numbness, or weakness in the shoulder, arm, or hand.
Yes. Some slipped discs are found incidentally on imaging performed for another reason and cause no symptoms at all. A disc herniation only tends to cause noticeable symptoms when it presses on a nearby nerve root or the spinal cord.
Seek urgent medical care immediately if you experience:
These symptoms may indicate a rare but serious condition called cauda equina syndrome, which requires emergency evaluation and treatment.
Diagnosis usually starts with a medical history and physical examination. Your doctor may check:
Imaging is often used to confirm the diagnosis and determine the exact location and severity of the disc herniation.
MRI is the preferred imaging test for evaluating a suspected slipped disc. It provides detailed images of the discs, nerves, spinal cord, and surrounding soft tissues without using radiation.
MRI can help assess:
For persistent or unexplained back pain, our guide on back pain reasons and diagnosis explains when further evaluation may be needed.
MRI findings vary depending on the type and severity of the herniation.
The disc extends slightly beyond its normal space but the outer layer remains largely intact.
A more focal portion of the disc pushes outward while the outer layer is still mostly intact.
Disc material breaks through the outer layer and extends beyond the disc space, but often remains connected to the disc.
A fragment of disc material separates completely and can migrate within the spinal canal.
MRI can also show whether the herniated material is compressing a nerve root or the spinal cord, and whether there is associated swelling or degeneration of the disc.
An X-ray does not usually show a slipped disc directly, since discs and nerves are soft tissues that do not appear clearly on X-ray. However, an X-ray can help rule out other causes of back pain, such as fractures or alignment problems. MRI remains the primary tool for confirming a disc herniation.
Back pain can come from several sources, and it is not always easy to tell them apart without imaging.
| Feature | Slipped Disc | Muscle Strain |
|---|---|---|
| Pain radiating to arm/leg | Common | Uncommon |
| Numbness or tingling | Common | Rare |
| Muscle weakness | Can occur | Uncommon |
| Onset | Gradual or sudden | Usually sudden, after activity |
| Pain with coughing/sneezing | Often worsens | Usually unaffected |
| MRI needed | Often, to confirm | Rarely required |
A doctor's examination, combined with MRI when needed, can help distinguish between these and other causes of back pain.
Treatment depends on the severity of symptoms, the location of the herniation, and whether there is nerve compression.
Most people with a slipped disc improve with non-surgical treatment, including:
Surgery may be considered when:
The type of procedure depends on the location and severity of the herniation and is decided in consultation with a spine specialist.
Yes, in many cases. A significant proportion of slipped discs improve over time as inflammation settles and the body reabsorbs some of the herniated material. Symptoms often improve within a few weeks to a few months with conservative treatment, although recovery time varies between individuals.
Recovery time depends on the severity of the herniation, the treatment approach, and individual factors. Many people notice improvement within several weeks, while others may take a few months to recover fully. Following your physiotherapy program and activity guidance can support a smoother recovery.
Gentle movement and specific exercises are often recommended, since prolonged bed rest can slow recovery. However, high-impact activities, heavy lifting, and certain twisting movements may need to be avoided until your symptoms improve. A physiotherapist can guide you on which exercises are appropriate for your condition.
MRI may be recommended when there is:
If you also experience frequent headaches alongside neck pain, our guide on frequent headaches, causes, symptoms, and diagnosis may be helpful.
Preparation depends on whether contrast is required. Before the scan, tell the MRI team if you:
If contrast is planned, our guide on MRI contrast agent safety explains what to expect. If you have a larger body size, our guide on MRI for obese patients explains what to know before your scan.
You will usually lie on your back on the MRI table while the area of your spine being examined is positioned within the scanner. The scan involves loud knocking or tapping sounds, so hearing protection is generally provided. It is important to remain still, as movement can reduce image quality. A spine MRI is non-invasive and does not use ionizing radiation.
Seek medical assessment if you experience:
Prompt assessment can help identify whether a slipped disc or another condition is responsible.
A slipped disc can cause pain, numbness, and weakness that affect daily activities, but many cases improve with the right treatment. While symptoms can point toward a disc problem, imaging is often needed to confirm the diagnosis and guide treatment.

Book Your Spine MRI MRI Scan ServicesPain that radiates from the back or neck into an arm or leg, often with numbness, tingling, or weakness, is a common feature of a slipped disc.
Yes. MRI provides detailed images of the spinal discs and nerves and can show the location, size, and severity of a disc herniation.
Yes, many slipped discs improve with non-surgical treatment such as physiotherapy, activity modification, and pain management. Surgery is generally considered only when symptoms do not improve or when there are signs of significant nerve compression.
Recovery time varies, but many people see improvement within a few weeks to a few months with conservative treatment.
Gentle walking is often encouraged as part of recovery, as it can help maintain mobility without placing excessive strain on the spine. Your doctor or physiotherapist can advise on the right level of activity for your condition.
No. Most people improve with non-surgical treatment. Surgery is usually considered only when conservative treatment fails or when there are signs of significant nerve involvement.
