Spinal Pain Block vs Surgery

If you’re suffering from persistent back or leg pain, especially due to a herniated disc or nerve compression, you’ve likely come across two common options: spinal pain blocks and spine surgery. But how do you decide which one is right for you?

At London Spine Health, we tailor every treatment plan to the individual — and that begins with helping you understand your options. Here’s a breakdown of both spinal injections (pain blocks) and surgical interventions, along with guidance on when each is most appropriate.

What Is a Spinal Pain Block?

A spinal pain block, also known as a nerve root block or epidural steroid injection, is a minimally invasive procedure used to reduce inflammation and relieve pain caused by spinal conditions such as:

  • Herniated or slipped discs

  • Sciatica (nerve compression)

  • Spinal stenosis

  • Degenerative disc disease

  • Facet joint pain

During the procedure, a steroid and local anaesthetic are injected directly near the affected nerve root or spinal joint. The goal is to numb the pain, reduce inflammation, and improve mobility.

Benefits of Pain Blocks:

  • Quick procedure (often 15–30 minutes)

  • No hospital stay required

  • Minimal recovery time

  • Can delay or avoid the need for surgery

  • Used as a diagnostic tool to locate the pain source

However, pain relief is temporary — typically lasting from a few days to several months. It’s often part of a broader treatment plan including physiotherapy and activity modification.

What Is Spine Surgery?

Spine surgery is aimed at correcting the underlying cause of back or leg pain — not just managing the symptoms. Common surgical options include:

  • Microdiscectomy – to remove part of a herniated disc

  • Laminectomy – to relieve pressure from spinal stenosis

  • Spinal fusion – to stabilise the spine in cases of severe degeneration or instability

  • Robotic-assisted or endoscopic surgery – for minimally invasive access and faster recovery

Surgery is typically considered when conservative treatments, including injections, have failed, or when nerve damage or spinal instability is present.

Benefits of Spine Surgery:

  • Targets and resolves the root cause

  • Long-term relief for nerve compression

  • Improved mobility and quality of life

  • Increasingly performed through minimally invasive techniques

  • High success rates for selected conditions

Key Differences: Spinal Pain Block vs Surgery

AspectSpinal Pain BlockSpine Surgery
PurposePain relief (temporary)Corrects the underlying issue
InvasivenessMinimally invasive injectionRanges from minimally to moderately invasive
Recovery Time1–2 days2–12 weeks depending on procedure
Duration of ReliefTemporary (weeks to months)Long-term or permanent
Used ForMild to moderate casesSevere or persistent cases
RisksLow risk, occasional side effectsSlightly higher, but often very safe in skilled hands

When Should You Choose a Spinal Pain Block?

You might benefit from a spinal pain block if:

  • You have acute nerve pain and need fast relief

  • You’re undergoing physiotherapy and need temporary pain control

  • You’re not ready for surgery or want to avoid it

  • Your condition is not yet severe enough to warrant surgery

  • Your doctor wants to diagnose the exact pain source

Pain blocks can provide a window of relief to support recovery, but they are rarely a long-term solution on their own.

When Is Spine Surgery the Better Option?

Spine surgery is often recommended when:

  • Pain has lasted over 6–12 weeks despite all non-surgical treatments

  • You experience progressive numbness, weakness, or mobility loss

  • You have spinal instability, fractures, or deformity

  • There’s a risk of permanent nerve damage (e.g. foot drop, cauda equina)

  • You’ve had repeated pain block injections with only short-term benefit

At London Spine Health, we use the least invasive method possible — often robotic or endoscopic — to maximise safety and minimise recovery time.

Expert Guidance Makes All the Difference

Choosing between a pain block and surgery isn’t a decision you have to make alone. Our team at London Spine Health takes time to evaluate your MRI, history, lifestyle, and goals before recommending a personalised care pathway.
