Conservative management
Physiotherapy, activity modification, pain medication, anti-inflammatory medication, and nerve pain medication are common first-line approaches. Many patients improve without surgical intervention.

Sciatica and Slipped Disc Assessment
Sciatica commonly refers to nerve pain that travels from the lower back or buttock into the leg. One possible cause is a lumbar slipped disc, but other spine conditions can produce similar symptoms.
A proper assessment helps determine whether symptoms match MRI findings and whether treatment should involve observation, medication, physiotherapy, injections, or surgery.

Quick summary
About this page
This page explains sciatica and slipped disc and when neurosurgical assessment may be appropriate.
Who this is for
Patients with back pain, leg pain, numbness, or weakness seeking general information before a non-emergency consultation.
When to request assessment
Request assessment if symptoms persist, affect limb function or walking, or if MRI findings need clinical interpretation.
Emergency symptoms
Sudden weakness, loss of bladder or bowel control, saddle numbness, or rapidly worsening leg weakness — attend the nearest Emergency Department immediately.
Understanding sciatica
What is sciatica?
The term "sciatica" describes pain that radiates along the path of the sciatic nerve — from the lower back through the buttock and down the leg, sometimes reaching the foot. It is a symptom, not a diagnosis in itself.
Common causes
The most common cause is compression of a lumbar nerve root by a herniated disc. Other causes include spinal stenosis (narrowing of the spinal canal), bony spurs pressing on a nerve, or spondylolisthesis (slippage of a vertebra).
What a slipped disc means
A "slipped disc" — medically called a herniated or prolapsed disc — occurs when the inner gel-like material of a spinal disc pushes through its outer layer and presses on a nearby nerve. This can cause pain, numbness, or weakness in the leg.
Symptoms
Common symptoms
Pain in the lower back that radiates into one or both legs
Burning, sharp, or shooting pain down the leg
Numbness, tingling, or pins and needles in the leg or foot
Weakness in the leg or foot
Pain that worsens on sitting, coughing, or sneezing
Difficulty walking or standing for prolonged periods
Investigations
When MRI is useful
MRI is the most useful imaging investigation for suspected disc herniation or spinal stenosis. It can show the disc, the nerves, and the degree of compression. However, MRI findings must always be interpreted alongside clinical symptoms and neurological examination.
MRI findings alone are not enough
An MRI may show a disc herniation that does not match the patient's symptoms, or may not fully explain why symptoms are present. Clinical correlation — matching what is seen on MRI with what the patient feels and what is found on examination — is essential before any treatment decision.
Not all disc herniations need treatment
Many disc herniations seen on MRI are asymptomatic or cause only mild symptoms. Research shows that a significant proportion of disc herniations improve naturally over time with conservative management.
Treatment options
Does a slipped disc always need surgery?
No. Many cases of lumbar disc prolapse improve with conservative treatment. Surgery is considered when symptoms are persistent, severe, or associated with progressive neurological change.
Injections
Epidural steroid injections or nerve root blocks may reduce inflammation and relieve pain in selected cases. These are typically considered when medication and physiotherapy have not achieved sufficient relief.
Surgical options
Surgery may be considered when symptoms are severe, persistent, or associated with neurological deficit. Options include microscopic discectomy, endoscopic discectomy, or spinal decompression depending on the clinical situation.
Understanding the options
What do decompression and discectomy involve?
Decompression aims to relieve pressure on a nerve. Discectomy removes the part of a herniated disc that is compressing the nerve. In selected cases, an endoscopic camera or a microscope may help the surgeon access the affected area. The approach depends on the location of compression, anatomy and clinical findings.
When surgery may be considered
Surgery may be discussed for persistent disabling leg pain despite appropriate non-surgical treatment, progressive weakness, or significant nerve compression that matches the symptoms and examination. An MRI finding alone does not decide whether surgery is needed.
Limitations of surgery
Decompression treats the selected source of nerve pressure; it does not reverse every age-related disc change. Back pain, numbness or weakness may persist, and improvement is not guaranteed. Fusion is considered only when there is a specific structural indication, such as instability or deformity.
Before an operation
Non-surgical care remains part of the discussion
Depending on the diagnosis and neurological findings, options may include education, activity modification, medication, guided physiotherapy, monitoring or targeted injections. Treatment should be reviewed if symptoms persist or worsen. Progressive weakness or bladder and bowel symptoms require urgent assessment rather than waiting for a routine appointment.

Recovery and preparation
Recovery varies from person to person
Recovery depends on the procedure, the duration and severity of nerve compression, general health and work demands. Relief of leg pain and recovery of numbness or weakness may follow different timelines. Hospital stay, rehabilitation, driving and return to work should be discussed individually; this page does not promise a fixed recovery time.
Bring the information needed for a useful assessment
- Actual MRI images and the report, plus previous scans or X-rays if available
- A symptom timeline, including pain distribution, weakness and walking limitations
- Your medication list and records of physiotherapy, injections or previous surgery
- Any referral letter and the questions you want answered before deciding
Safety first
When to seek urgent care
Severe or rapidly worsening weakness, numbness around the groin, or bladder and bowel changes require urgent emergency assessment — not a routine appointment.
Attend Emergency immediately
- Loss of bladder or bowel control
- Numbness around the groin or saddle area
- Rapidly worsening leg weakness
- Both legs suddenly weak or numb
Seek earlier specialist review
- Progressive foot drop or leg weakness
- Symptoms not improving after several weeks
- Significant impact on daily function or walking
Also consider assessment for
- Abnormal MRI needing clinical interpretation
- Second opinion before proceeding with surgery
- Symptoms returning after previous treatment
For emergency symptoms, attend the nearest Emergency Department immediately. This website is not monitored for emergencies.
Next step
Request a spine assessment
Consultation includes symptom history, neurological examination, and MRI review. The clinic team will confirm appointment availability after receiving your request.
