What is a herniated disc?
Between the bones of your spine sit the discs - tough rings of cartilage with a soft, gel-like center that cushion the spine and let it bend. A herniated disc (also called a slipped, ruptured, or prolapsed disc) happens when that soft center pushes through a tear in the outer wall. If the displaced material presses on a nearby spinal nerve, it can trigger pain, numbness, or weakness that travels well beyond the back itself.
In the lower back, this often shows up as sciatica - pain radiating through the buttock and down the leg. In the neck, it can send pain, pins-and-needles, or weakness into the shoulder and arm. Many herniated discs, though, cause no symptoms at all and are found only by chance on a scan.
The reassuring part: most herniated discs improve without surgery. Our role is to confirm what is actually driving your symptoms and guide you to the least invasive treatment that gives a durable result.
Symptoms to look for
The pattern depends on which nerve is affected and where the disc sits:
- Radiating pain - sciatica down the leg (lower back) or into the arm (neck), often sharp or electric.
- Numbness or tingling in the area that nerve supplies.
- Muscle weakness - for example a weak foot or ankle, or a weaker grip.
- Back or neck pain that may ease when lying down and worsen with sitting, bending, coughing, or sneezing.
Symptoms range from mild and short-lived to persistent. A careful examination - not the scan alone - is what tells us whether the disc is truly the source.
CAUTION
New loss of bladder or bowel control, numbness around the groin or inner thighs, or rapidly worsening weakness can signal serious nerve compression. Treat these as an emergency and seek immediate medical attention.
What causes a herniated disc?
Most herniations are the result of gradual wear as discs lose water content and flexibility with age - which is why they are most common between 30 and 55. A single bend, lift, or twist can be the final trigger, but the groundwork is usually laid over years. Long hours seated at a desk, heavy or repetitive lifting, carrying extra weight, and smoking all raise the risk.
How we diagnose it
Diagnosis begins with your history and a focused neurological examination to map exactly which nerve is involved. An MRI is the clearest way to see the disc and the nerve, and in some cases nerve conduction studies (EMG) or an X-ray help confirm the picture or rule out other causes.
Just as important, we match the imaging to your symptoms. Scans in healthy, pain-free people often show disc changes, so we treat the person - not the picture. Your assessment is led by a US board-certified neurosurgeon.
Treatment - least invasive first
We follow a measured, surgery-last approach. For most people that means starting with non-surgical care and escalating only if the evidence calls for it.
- Non-surgical care (first line for most). Staying gently active, physiotherapy, and anti-inflammatory medication give the nerve time to settle - most people improve within about six weeks.
- Targeted injections. If radiating pain persists, an image-guided epidural steroid injection can calm nerve inflammation and support recovery without surgery.
- Minimally invasive surgery (when it is warranted). If severe pain lasts beyond six weeks, weakness is progressing, or a red flag is present, removing the fragment pressing on the nerve can relieve the radiating pain, often quickly. Where suitable, we use endoscopic discectomy - a small camera through a tiny, muscle-sparing incision, frequently as a day case. Microdiscectomy remains a reliable, well-established option, and the right choice depends on the size and position of your herniation rather than on the technique itself.
If you have already been told you need surgery, we are glad to give an honest second opinion on whether a less invasive path could work for you.
What to expect
With non-surgical care, expect gradual improvement over several weeks rather than an overnight change. If you do have endoscopic surgery, the incision is small, many patients go home the same day, and a guided return to normal activity follows - your surgeon will explain the timeline and any precautions for your specific case. Either way, the plan is built around you, with clear explanations at every step.
Common questions
How long does a herniated disc take to heal?
Most herniated discs improve within about six weeks, and the majority settle within three months with the right non-surgical care. The timeline depends on the size and position of the herniation and your general health - your specialist can give you a realistic estimate once your symptoms and MRI are reviewed.
Does a herniated disc heal without surgery?
Usually, yes. Most herniated discs improve without an operation as the body gradually reabsorbs the displaced material, helped by physiotherapy, activity changes, and - if needed - a targeted injection to settle nerve inflammation. Surgery is considered only when symptoms are severe, persistent, or a nerve is at risk.
Do I need surgery for a herniated disc?
Rarely. Surgery is usually reserved for pain that hasn't responded to six or more weeks of non-surgical care, muscle weakness that is getting worse, or urgent red-flag symptoms. If an operation has already been recommended to you, an independent second opinion can confirm whether a less invasive path is possible.
What is the difference between a herniated disc and a bulging disc?
A bulging disc has widened beyond its normal edge, but the tough outer wall is still intact. A herniated - or 'slipped' - disc means the soft inner material has pushed through a tear in that wall, so it is more likely to press on a nerve and cause radiating pain, numbness, or weakness.
What is endoscopic discectomy, and how is it different from microdiscectomy?
Both procedures remove the fragment of disc pressing on the nerve. Endoscopic discectomy uses a small camera through a tiny, muscle-sparing incision, so less tissue is disturbed on the way to the disc. Both are established ways of doing the same job, and which one suits you depends on the size and position of the herniation.
What warning signs should I not ignore?
Seek urgent medical care if you develop new loss of bladder or bowel control, numbness around the groin or inner thighs, or rapidly worsening weakness in a leg or arm. These can signal serious nerve compression that needs prompt assessment.
