FAQ: MRI for Sciatica and Nerve Compression

What is sciatica?

Sciatica refers to pain that travels from the lower back down the buttock and leg, usually following the path of the sciatic nerve. It is commonly caused by nerve compression in the lumbar spine, often from a slipped disc, disc bulge, or spinal narrowing.

Is sciatica always caused by a slipped disc?

No. While slipped discs are common causes, sciatica can also result from:

• Disc bulges without full herniation

• Spinal canal or foraminal narrowing

• Degenerative changes of the spine

• Inflammation around the nerve

MRI helps identify the exact cause and location of nerve compression.

Do all cases of sciatica need an MRI?

Not always.

An MRI is usually considered when:

• Leg pain persists beyond a few weeks

• Symptoms are worsening or recurrent

• There is numbness, tingling, or weakness

• Pain significantly affects walking, work, or sleep

• Initial treatment does not provide sustained relief

Why is MRI important for nerve-related pain?

MRI is the best imaging method to visualise:

• Nerves and nerve roots

• Discs and surrounding soft tissue

• Areas of compression or inflammation

X-rays cannot show nerves or discs clearly and are therefore limited in evaluating sciatica.

When should MRI be done urgently for sciatica?

MRI is more urgently considered when sciatica is associated with:

• Progressive leg weakness

• Increasing numbness

• Difficulty controlling movement

• Severe, unrelenting pain

Early imaging helps guide timely and appropriate care.

How long does it take to get an MRI for sciatica in Singapore?

This depends on the care pathway:

• Public hospitals:
  Non-urgent outpatient MRI scans may involve waiting weeks or more, depending on demand.

• Private or clinic-based options:
  MRI scans are usually arranged much faster.

At The Pain Relief Clinic, MRI scans for sciatica and nerve compression can typically be arranged within one working day, subject to clinical suitability.

How much does an MRI for sciatica cost in Singapore?

Costs vary depending on provider and scan details:

• Public hospitals:
  Lower out-of-pocket costs with subsidies, but longer waiting times.

• Private hospitals / imaging centres:
  Higher and sometimes variable pricing.

• The Pain Relief Clinic:

  • Clear upfront pricing, typically under S$1,000 for common outpatient lumbar spine MRI scans

  • Costs explained before proceeding, allowing patients to plan financially

Do I need to go to another location for the MRI?

In many cases, patients need to:

• Consult a doctor at one clinic

• Travel to a separate imaging centre

• Return again for review

At The Pain Relief Clinic:

• MRI coordination is handled within the same clinic system

• No off-site imaging travel is required

• Faster review and smoother care coordination

Can Medisave be used for MRI scans for sciatica?

Yes. Medisave can be used for outpatient MRI scans, subject to prevailing outpatient diagnostic limits.

Patients can check:

• Eligibility for Medisave use

• Expected out-of-pocket costs
  before proceeding with the scan.

Are insurance claims or instalment options available?

Depending on coverage, patients at The Pain Relief Clinic may access:

• Insurance claim support (corporate and personal plans, subject to insurer rules)

• Cashless arrangements where applicable

• Interest-free instalment plans

• Cash and card payments

This flexibility helps manage unexpected medical expenses.

What happens after the MRI?

After the MRI:

• Imaging findings are reviewed in relation to symptoms

• The location and cause of nerve compression are explained clearly

• Next steps may include targeted conservative care, further evaluation, or referral if needed

Clear imaging helps avoid unnecessary delays or ineffective treatments.
