Slipped Disc: Causes, Symptoms, Diagnosis and Treatment

Back pain can develop after lifting, bending, exercising, or sometimes without an obvious trigger. In some cases, the problem involves one of the discs that sit between the bones of the spine.

A slipped disc, also called a herniated disc, prolapsed disc, or disc herniation, occurs when part of the soft inner material of a spinal disc pushes through a weakened or damaged outer layer. Although the term “slipped disc” is commonly used, the disc does not actually slip out of position.

Many slipped discs cause no symptoms. However, when the disc irritates or compresses a nearby nerve, it can cause back pain, leg pain, numbness, tingling, or weakness.

Fortunately, most people improve with appropriate non-surgical treatment. However, significant or worsening neurological symptoms require prompt medical evaluation.

At Jyoti Hospital, Gurugram, our orthopaedic team evaluates the underlying cause of back and nerve-related symptoms before recommending treatment.

What Is a Slipped Disc?

Your spine consists of a series of vertebrae separated by flexible discs. These discs act as cushions and allow the spine to move.

Each disc has:

• A tough outer layer
• A softer inner portion

With ageing, repeated stress, or injury, the outer layer can weaken or tear. As a result, the inner material can push outward and irritate nearby nerves.

A slipped disc can occur anywhere along the spine, although the lower back is one of the most common locations.

What Causes a Slipped Disc?

Several factors can contribute to disc herniation.

• Age-related changes: As you age, spinal discs gradually lose flexibility and water content. Consequently, they may become more vulnerable to tearing or herniation.
• Heavy lifting: Lifting heavy objects, particularly with poor technique, can place considerable stress on the spine.
• Repetitive movements: Repeated bending, twisting, or physically demanding activities can increase stress on spinal discs.
• Prolonged sitting: Long periods of sitting or driving can contribute to back strain, particularly when combined with inactivity.
• Excess body weight: Extra weight can increase the mechanical load on the spine.
• Smoking: Smoking can weaken disc tissue and negatively affect spinal health.
• Previous injury: A previous back injury may also increase the risk of disc problems.

Symptoms of a Slipped Disc

Not every slipped disc causes symptoms.

When symptoms occur, they may include:

• Lower back pain
• Pain spreading into the buttock or leg
• Numbness
• Tingling or pins and needles
• Muscle weakness
• Difficulty bending or straightening the back
• Neck pain when a cervical disc is affected

The exact symptoms depend on the location of the affected disc and whether it irritates a nerve.

Slipped Disc in the Lower Back

A lumbar slipped disc can cause pain in the lower back and, if it affects a nerve, pain that travels into the buttock and leg.

You may also experience:

• Tingling in the leg or foot
• Numbness
• Weakness in the leg or foot
• Difficulty walking comfortably

When nerve irritation produces pain along the sciatic nerve distribution, doctors may describe the symptoms as sciatica.

Slipped Disc in the Neck

A slipped disc in the cervical spine can irritate nerves supplying the arm.

Depending on the affected nerve, symptoms may include:

• Neck pain
• Shoulder pain
• Arm pain
• Tingling in the hand or fingers
• Numbness
• Arm or hand weakness

Therefore, the location of your symptoms can provide important clues about the affected part of the spine.

How Is a Slipped Disc Diagnosed?

Our doctors usually begin with your medical history and physical examination.

Our orthopaedic doctor assess:

• Location of pain
• Muscle strength
• Sensation
• Reflexes
• Walking pattern
• Spinal movement
• Nerve-related symptoms

In many cases, doctors can initially assess a suspected slipped disc from the symptoms and examination.

Do You Need an MRI?

Not necessarily.

Our doctors do not routinely recommend imaging for every person with uncomplicated back pain.

An MRI may become appropriate when:

• Symptoms persist despite treatment
• Significant neurological symptoms develop
• The diagnosis remains uncertain
• Surgery is being considered
• The examination suggests substantial nerve compression

MRI can show the discs, spinal canal, nerves, and surrounding soft tissues.

However, an abnormal MRI does not automatically mean that you need surgery. Doctors need to match the scan findings with your symptoms and examination.

Treatment for a Slipped Disc

Most people do not require surgery.

Treatment generally begins with conservative measures and depends on the severity of symptoms.

1. Stay Active: Although severe pain may temporarily limit activity, prolonged bed rest is generally not recommended. Instead, gradually return to gentle activities such as walking as your symptoms allow.
2. Pain Management: Doctors may recommend appropriate pain-relieving medicines depending on your symptoms and medical history.
   • Anti-inflammatory medicines may help some patients, but they are not suitable for everyone.
   • Therefore, consult a doctor or pharmacist before using them, particularly if you have kidney, stomach, heart, or other medical problems.
3. Physiotherapy: Our physiotherapist can develop an exercise programme based on your symptoms and recovery stage. It can help restore:
   • Mobility
   • Strength
   • Flexibility
   • Core control
   • Functional movement
4. Activity Modification: During an acute episode, temporarily reduce activities that significantly worsen your symptoms. As your symptoms improve, gradually return to normal activity rather than remaining inactive for prolonged periods. These may include:
   • Heavy lifting
   • Repeated bending
   • Forceful twisting
   • High-impact activities
5. Injections: In selected patients with severe nerve-related symptoms, doctors may consider an epidural injection containing local anaesthetic and steroid. NICE recommends considering epidural injections for acute and severe sciatica, rather than routine injections for uncomplicated low back pain.

When Is Surgery Required?

Most slipped discs improve without surgery.

However, a specialist may consider surgery when:

• Symptoms remain disabling despite appropriate non-surgical treatment
• Significant or progressive weakness develops
• Severe neurological compression occurs
• Imaging confirms nerve compression that matches the symptoms

For suitable patients with persistent sciatica, NICE recommends considering spinal decompression when non-surgical treatment has not improved pain or function and imaging findings correspond with the symptoms.

What Is Discectomy?

A discectomy removes the portion of disc material that is compressing a spinal nerve.

The surgeon aims to:

1. Identify the affected nerve
2. Access the compressed area
3. Remove the problematic disc fragment
4. Relieve pressure on the nerve

The rest of the disc is generally left in place.

The purpose of surgery is to relieve nerve compression, not simply to remove an abnormality seen on an MRI.

Can a Slipped Disc Heal Without Surgery?

Yes.

Many people improve gradually with appropriate conservative treatment. The body can reduce inflammation around the affected nerve, and some disc herniations can decrease in size over time.

Therefore, finding a slipped disc on an MRI does not automatically mean that surgery is necessary.

How Long Does Recovery Take?

Recovery varies from person to person.

It depends on:

• Size and location of the disc herniation
• Degree of nerve irritation
• Duration of symptoms
• Overall health
• Activity level
• Response to treatment

Many people improve over several weeks, although some symptoms may take longer to settle.

Can You Exercise With a Slipped Disc?

In most cases, appropriate movement forms an important part of recovery.

Depending on your symptoms, your rehabilitation programme may include:

• Walking
• Gentle mobility exercises
• Core strengthening
• Hip strengthening
• Flexibility exercises
• Gradual return to normal activities

However, avoid exercises that significantly increase pain or cause new numbness or weakness.

What Should You Avoid?

During an acute flare-up, avoid activities that clearly worsen your symptoms.

These may include:

• Heavy lifting
• Repeated bending
• Forceful twisting
• Sudden high-impact exercise
• Prolonged bed rest
• Returning to heavy gym training too quickly

Instead, gradually rebuild your activity under appropriate guidance.

How Can You Prevent a Slipped Disc?

You cannot prevent every disc problem. Nevertheless, several habits can support spinal health.

• Stay physically active: Regular activity helps maintain muscle strength and mobility.
• Maintain a healthy weight: A healthy weight can reduce mechanical stress on the spine.
• Use safe lifting techniques: Avoid lifting heavy objects with poor posture or twisting movements.
• Avoid smoking: Smoking can negatively affect disc tissue.
• Strengthen your core: A suitable strengthening programme can improve spinal support and overall physical function.

When Should You See an Orthopaedic Doctor?

Arrange an evaluation if:

• Back pain persists for several weeks
• Pain is getting worse
• Pain interferes with daily activities
• You develop persistent numbness or tingling
• You notice muscle weakness
• Symptoms repeatedly return
• Treatment does not provide adequate improvement

Prompt evaluation becomes particularly important when neurological symptoms develop.

Emergency Warning Signs

Seek urgent medical attention if back pain occurs with:

• Numbness around the genitals or anus
• Difficulty starting urination
• Inability to urinate
• Loss of bladder control
• Loss of bowel control
• Severe or worsening weakness in both legs
• Numbness affecting both legs

These symptoms can indicate cauda equina syndrome, which requires urgent assessment.
