Herniated Disc

The discs between your vertebrae have a tough outer ring and a soft gel centre. In a herniated (slipped or prolapsed) disc, some of the centre pushes out through a tear in the ring and can press on or chemically irritate a nearby nerve root. In the lower back this causes sciatica, pain that travels down the leg; in the neck it causes arm pain. Most lumbar herniations occur at L4-L5 or L5-S1.

The natural history is favourable. Most people improve substantially within 6 to 12 weeks, and the herniated fragment frequently shrinks as the body absorbs it. Surgery relieves leg pain faster in those who do not settle, but results at 1 to 2 years are similar with or without an operation for many patients. Surgery treats nerve pain in the limb far better than it treats back or neck ache.

Symptoms

• Sharp, shooting or burning pain from the buttock down the leg, often below the knee
• Leg pain that is worse than the back pain
• Pain worse with sitting, bending, coughing or sneezing
• Numbness or pins and needles in part of the leg or foot
• Weakness, such as a foot that slaps or difficulty rising on tiptoe
• With a neck disc: pain radiating into the shoulder blade, arm and particular fingers
• Many disc bulges cause no symptoms and are found incidentally on MRI

Causes and risk factors

Discs lose water and resilience with age, so small tears form in the outer ring. Herniation peaks between 30 and 50. Contributing factors include inherited disc characteristics, heavy or repetitive lifting and twisting, whole-body vibration from long-distance driving, smoking and obesity. Often there is no single incident, although a lift or a sneeze can be the final trigger. Disc bulges are very common on scans of people without pain, so the MRI finding must match your symptoms and examination to be meaningful.

How it is diagnosed

• Neurological examination: Straight leg raise, reflexes, muscle power and sensation identify which nerve root is affected.
• MRI: The test of choice. Usually arranged if symptoms persist beyond about 6 weeks, if surgery or injection is being considered, or immediately with red flags.
• CT or CT myelogram: An alternative when MRI is not possible.
• Nerve conduction studies and EMG: Occasionally used to separate nerve root compression from peripheral nerve problems.
• X-rays: Do not show discs; used to assess alignment, slippage or instability.

Treatment options

• Staying active: Keep moving within the limits of pain. Bed rest beyond a day or two slows recovery.
• Pain relief: Anti-inflammatories and paracetamol, with short courses of stronger drugs if needed. Nerve pain medicines such as gabapentinoids show little benefit for sciatica in trials.
• Physiotherapy: Directional exercises, nerve mobility work and graded strengthening.
• Epidural or nerve root steroid injection: Can reduce leg pain for weeks to months while natural recovery takes place.
• Microdiscectomy: Removal of the fragment pressing on the nerve through a small incision under a microscope, with 1 night or less in hospital.
• Endoscopic discectomy: The same aim through a smaller portal; outcomes are broadly comparable in suitable cases.
• Neck disc surgery: Anterior cervical discectomy with fusion, or artificial disc replacement, for persistent arm pain or spinal cord compression.

When it is urgent

Go to an emergency department locally at once for numbness around the genitals, buttocks or back passage, new difficulty passing urine, loss of bladder or bowel control, weakness in both legs, or rapidly worsening weakness such as foot drop. These suggest cauda equina syndrome or severe nerve compression, where delay of even a day can cause permanent damage.

Travelling to Türkiye for treatment

Since most herniations settle without surgery, there is rarely a reason to travel in the first 6 weeks unless pain is unmanageable. Travel makes sense for a second opinion with a fresh look at your MRI, or for planned microdiscectomy or endoscopic surgery when leg pain has persisted for 6 to 12 weeks and the scan matches. Expect roughly 5 to 7 days on site. Sitting through a long flight with acute sciatica is hard; book an aisle seat and walk regularly. Be wary of offers of laser or ozone disc treatments with big promises, as the evidence for them is weak.
