Slipped (Herniated) Disc:
Symptoms, Causes and Treatments
Have you noticed your back or neck pain lingering longer than it should, or flaring up with simple movements like bending, sitting or turning your head? What may begin as mild stiffness can gradually develop into recurring discomfort, numbness or sharp pain that travels into the arms or legs. When these symptoms persist despite rest and stretching, they may point to an underlying spinal condition that deserves proper evaluation.
At HC Orthopaedic Surgery, we provide evidence-based assessment and slipped disc treatment options tailored to the source of your symptoms. Our focus is on relieving nerve compression, restoring stability and helping you return to daily activities with greater comfort and confidence.
What Are the Common Symptoms of a Slipped Disc?
A slipped disc, also known as a herniated disc, occurs when the inner gel-like material of an intervertebral disc bulges or protrudes through a weakened outer layer. If the herniated disc compresses a nearby nerve, symptoms may develop depending on its location and severity.
Sciatica and Radiating Pain
One of the most common signs of a lumbar slipped disc is sciatica. This presents as sharp, burning pain that radiates from the lower back through the buttock and down one leg along the path of the sciatic nerve. If the herniation occurs in the cervical spine, similar radiating pain may travel from the neck into the shoulder, arm or hand.
Numbness and Tingling
Patients may experience a pins-and-needles sensation or reduced sensation in the area supplied by the affected nerve. These sensory changes may follow a specific nerve distribution.
Unexplained Muscle Weakness
If the compressed nerve controls muscle function, weakness may develop. This can present as difficulty lifting the foot, reduced grip strength or trouble performing routine tasks.
Aggravated Pain During Specific Activities
Pain often worsens with prolonged sitting, bending, coughing or sneezing, as these movements increase pressure within the spine. Some individuals may also notice discomfort at night.
Why It Happens
What Causes a Slipped Disc?
The spine is exposed to constant mechanical stress, particularly in the highly mobile lumbar and cervical regions. Over time, these stresses can contribute to disc degeneration and, in some cases, herniation.
Spinal Wear and Tear
With age, intervertebral discs gradually lose water content and disc height. As they become less flexible, they are more prone to small tears. This natural degenerative process increases the risk of a disc bulge or herniation, especially under repeated strain.
Physical Trauma and Accidents
Sudden impacts from falls, vehicular accidents or sports injuries can sharply increase pressure within a spinal disc and lead to herniation. In physically demanding environments such as military training, falls on uneven ground while carrying heavy equipment may similarly place acute stress on the spine.
Improper Lifting Techniques
Lifting heavy objects with poor technique, especially when bending forward and twisting at the same time, significantly increases pressure within the lumbar discs. Repeated strain or a single awkward lift can cause the outer layer of the disc to tear, allowing the inner material to protrude and irritate nearby nerves.
Know Your Risk Profile
What Are the Risk Factors for a
Slipped Disc?
While anyone can develop a slipped disc, certain lifestyle and biological factors increase the likelihood of the condition.
Occupation and Physical Strain
Jobs that involve repetitive lifting, bending, twisting or heavy manual labour place repeated mechanical stress on the spine. Over time, this may increase the risk of disc degeneration or herniation, particularly in the lower back.
Weight and Sedentary Lifestyle
Excess body weight increases mechanical load on the lumbar discs. At the same time, a lack of regular exercise may weaken the core and back muscles, reducing spinal support and increasing strain on the discs.
Genetics and Gender
Genetic factors may influence an individual’s susceptibility to disc degeneration and herniation. A family history of spinal problems can increase the likelihood of developing similar conditions. Slipped discs are also observed more frequently in men during early and middle adulthood, although the difference tends to narrow with age.
Understanding Your Evaluation
How Is a Slipped Disc Diagnosed?
Diagnosis begins with a detailed medical history and physical examination. Your doctor will assess spinal movement, reflexes, muscle strength and gait to determine whether nerve structures are affected. If further evaluation is needed, imaging or nerve studies may be recommended to confirm the diagnosis.

If further evaluation is needed, imaging or nerve studies may be recommended to confirm the diagnosis.
MRI Scan of the Spine
Magnetic resonance imaging is the gold standard for diagnosing a slipped disc. It provides detailed images of the discs, spinal cord and nerve roots, helping to identify the location and extent of nerve compression.
X-ray Imaging
Although X-rays cannot visualise the disc itself, they may be used to assess spinal alignment and rule out fractures or other structural abnormalities that could contribute to back pain.
Nerve Function Tests
Electromyography (EMG) and nerve conduction studies may be performed to evaluate how well electrical signals travel along the nerves. These tests help confirm nerve irritation and differentiate disc-related nerve compression from other nerve conditions.
Exploring Treatment Options
What Are the Treatments for Slipped Discs in Singapore
Our spine specialists in Singapore adopt a tiered approach to slipped disc treatment, beginning with conservative management before considering interventional or surgical options.
Non-Operative Conservative Management
Most patients improve with a combination of anti-inflammatory medication, short-term muscle relaxants and activity modification. Structured physiotherapy focusing on core strengthening and spinal stabilisation helps reduce strain on the affected disc and supports recovery.
Nerve Root Block
A selective nerve root block involves injecting a local anaesthetic and corticosteroid near the affected nerve under imaging guidance. This may provide temporary pain relief and reduce inflammation, allowing patients to participate more effectively in rehabilitation.
Minimally Invasive Nucleoplasty
In carefully selected cases with contained disc protrusions, nucleoplasty may be considered. This minimally invasive procedure uses controlled radiofrequency energy to reduce disc pressure by removing a small portion of the nucleus material. It is typically reserved for patients who do not respond to conservative treatment but do not require open surgery.
Microdiscectomy and Surgical Treatment
Slipped disc surgery may be recommended if significant pain persists despite adequate conservative therapy, or if there is progressive muscle weakness or severe nerve compression. Microdiscectomy is a commonly performed procedure in which the herniated portion of the disc compressing the nerve is removed. In more complex cases involving spinal canal narrowing, additional decompression procedures may be required.
Get Relief From a Slipped Disc at HC Orthopaedic Surgery
A slipped disc can affect daily comfort and mobility, making routine movements more difficult than they should be. Because each patient’s spinal anatomy and symptoms differ, a thorough clinical assessment is an essential first step. By identifying the exact source and severity of nerve compression, we can move beyond general measures and develop an evidence-based treatment plan tailored to your condition and recovery goals.
