A sudden backache after lifting something heavy can be alarming, especially when the pain travels down the leg. Sometimes, the problem is caused by a herniated or prolapsed disc, commonly known as a “slipped disc”.
While many cases improve with some rest and non-surgical treatment, symptoms such as persistent pain, numbness, or weakness should not be ignored. Knowing what causes the condition and when to get medical care can help you take the right next step.
What is a slipped disc?
The spine is made up of a series of bones called vertebrae. Between these bones are flexible discs that act as cushions and also help the spine move better. Each disc has a soft inner portion surrounded by a tougher outer layer.
A disc herniation occurs when some of the inner material pushes through a weakened or damaged area of the outer layer. If the displaced material irritates or compresses a nearby nerve, it can cause pain travelling along the arm or leg (known as sciatica), numbness or weakness of the muscles supplied by the irritated nerve.
A herniated disc most commonly affects the lower back region, although it can also occur in the neck.
Why does it happen?
A disc can become weaker over time as part of the natural ageing process. Repetitive everyday activities or an injury may then contribute to a tear or displacement.
Common factors associated with disc problems include:
- Age-related wear and changes in the discs
- Lifting heavy objects incorrectly
- Repetitive bending, twisting or physical strain
- Being overweight or obese
- Low levels of physical activity
- Smoking
- Certain physically demanding occupations
Not every episode of back pain is caused by a disc problem. In fact, non-specific low back pain is much more common than pain caused by a specific structural condition.
Slipped disc symptoms to watch for
Symptoms depend on where the affected disc is located and whether it is pressing upon a nerve.
Lower back and leg symptoms
A lumbar disc problem may cause:
- Pain in the lower back
- Pain that travels into the buttock, thigh or leg
- Numbness, tingling or pins and needles sensation along the leg
- Muscle weakness in the lower limb
- Pain that becomes worse with coughing, sneezing or certain movements
Pain travelling from the lower back into the leg is referred to as sciatica or radicular pain . WHO notes that nerve-related leg pain may be accompanied by numbness, tingling or muscle weakness.
Neck symptoms
If the affected disc is in the neck, symptoms can include neck stiffness and pain that spreads into the shoulder, arm or hand. Numbness, tingling or weakness may also occur. Movements of the neck may be painful.
When should you see a doctor?
Mild symptoms may settle with time and appropriate precautions taken by yourself. However, make an appointment with an orthopaedic surgeon if:
- Back or neck pain continues or keeps returning
- Pain interferes with sleep, work or daily activities
- Pain travels into an arm or leg
- You develop persistent numbness or tingling
- You notice weakness in the arm or leg
- Symptoms are getting worse despite self-care
A doctor can assess your symptoms and perform a physical examination before deciding whether further investigation is needed.
When is a slipped disc an emergency?
Certain symptoms require urgent medical attention because they may indicate significant nerve compression.
Seek emergency care if you develop:
- Loss of bladder or bowel control
- Difficulty passing urine
- Numbness around the genitals, buttocks or inner thighs
- Severe or rapidly worsening weakness in the legs
- Significant weakness accompanied by severe back pain
These symptoms can occur with serious nerve compression and should not be managed at home.
How is it diagnosed?
Diagnosis begins with your symptoms and a physical examination. Your doctor may check your muscle strength, sensation, reflexes and movement.
Imaging is not automatically required for every person with back pain. When a disc problem is suspected and imaging is clinically warranted, an MRI scan is commonly used because it provides detailed images of the discs and surrounding soft tissues.
An MRI finding does not always mean that the disc is responsible for a person's pain. The scan needs to be interpreted alongside symptoms and examination findings.
What are the treatment options?
Treatment depends upon the severity of symptoms, the affected area and whether a nerve is being compressed.
Medicines and activity modification: Your doctor may recommend medicines to control pain and inflammation. Short periods of relative rest may be helpful, but prolonged bed rest is generally not encouraged. Once the acute pain settles, gradual return to routine activities can hasten recovery.
Physiotherapy and exercises: WHO recommends rehabilitation and physical activity as important components of managing low back pain.
Physiotherapy may help restore movement, regain strength and improve function. A personalized program will usually include exercises for the back and abdominal muscles.
Injections: In selected patients with persistent nerve-related pain, a doctor may consider an epidural steroid injection. This is not suitable for everyone and should be discussed with a qualified specialist.
Surgery: Most people with a herniated disc do not need surgery. However, surgery may be considered when symptoms persist despite appropriate non-surgical treatment, or when there is significant neurological impairment.
Procedures such as microdiscectomy can remove the portion of the disc that is pressing on the nerves. The decision to operate depends on the individual patient's symptoms, examination findings and imaging.
What can you do at home?
If your symptoms are mild and there are no alarming signs, some simple measures may help:
- Move around slowly or with some help rather than remaining in bed for long periods.
- Avoid bending forwards especially lifting heavy objects until the pain improves.
- Take a walk or change positions to sit upright regularly if sitting for long periods.
- Follow exercises recommended by your doctor or physiotherapist.
- Maintain a healthy weight.
- Avoid smoking.
- Return to exercise gradually rather than suddenly increasing activity.
Good posture and safe lifting techniques may also reduce strain on the back.
Conclusion
A slipped disc does not automatically mean you need surgery. Many people improve with appropriate non-surgical treatment, physical rehabilitation and gradual return to normal activity.
However, persistent pain, numbness or weakness deserves medical assessment. If you develop bladder or bowel problems, numbness around the groin or rapidly worsening weakness, seek urgent medical care. The key is to understand your symptoms rather than relying only on an MRI report or assuming that every backache is caused by a disc problem.
