Nerve Block

Nerve Block for Diagnostic and Pain Relief Purposes

A nerve block is an image-guided injection used to temporarily interrupt pain signals from specific nerves. Nerve blocks may be used to diagnose the source of pain, reduce inflammation, or provide short-term pain relief as part of a comprehensive, non-surgical treatment plan.

At Motionis Medicine, nerve blocks are performed using advanced imaging as part of a physician-led, diagnosis-first approach.

Understanding the Procedure

WHAT IS A NERVE BLOCK?

Nerves transmit pain signals from injured or irritated tissues to the brain. A nerve block involves injecting a local anesthetic, sometimes combined with anti-inflammatory medication, near a specific nerve or group of nerves.

The goals of a nerve block may include:

Temporarily reducing pain signals

Identifying the specific nerve contributing to pain

Improving function and tolerance for activity

Guiding further treatment decisions

Nerve blocks are typically outpatient procedures and do not involve surgery.

When Is This Treatment Used?

CONDITIONS EVALUATED OR TREATED WITH NERVE BLOCKS

Nerve blocks are commonly used when pain is suspected to originate from a specific nerve pathway and may be associated with conditions such as:

Radiculopathy

involving nerve root irritation

Sciatica

with radiating leg pain

Neck Pain

related to nerve compression

Herniated Disc

causing nerve inflammation

Spinal Stenosis

narrowing spaces around nerves

Post-Surgical Pain

involving persistent nerve irritation

Nerve blocks are often considered when symptoms persist despite conservative treatments such as physical therapy or medications.

Targeted Based on Pain Location

TYPES OF NERVE BLOCKS

The type of nerve block used depends on the location and suspected source of pain. Examples include:

Selective nerve root blocks

Peripheral nerve blocks

Diagnostic nerve blocks

to isolate pain generators

Your physician will determine the most appropriate type based on clinical evaluation and imaging.

What to Expect

HOW A NERVE BLOCK IS PERFORMED

Nerve blocks are performed using real-time image guidance to ensure accurate placement of medication near the targeted nerve or nerve group responsible for pain transmission. On the day of the procedure:

STEP 01

Patient Positioning

Patients are positioned to allow precise access to the intended nerve pathway

STEP 02

Local Anesthesia

The skin is cleaned and numbed with a local anesthetic.

STEP 03

Image Guidance

Fluoroscopy or ultrasound guidance is used to identify the correct nerve location

STEP 04

Targeted Injection

Medication is carefully delivered adjacent to the nerve

STEP 05

Recovery Monitoring

Patients are monitored briefly before discharge.

The procedure typically takes 15–30 minutes, and most patients return home the same day.

Why This Procedure Is Often a Decision Point

HOW NERVE BLOCKS ARE USED IN PAIN EVALUATION & TREATMENT

Nerve blocks are used when pain is suspected to originate from a specific nerve pathway but the exact source needs clarification or targeted relief. Unlike treatments designed for long-term pain control, nerve blocks are often used to inform treatment direction rather than serve as a standalone solution.

Diagnostic Insight

Help determine whether a particular nerve is contributing to symptoms

Temporary Relief

Temporarily reduce nerve-related pain that limits movement or daily activity

Treatment Guidance

Clarify whether additional, longer-lasting treatments may be appropriate

Because the effects of a nerve block are temporary by design, the patient’s response is closely evaluated. Relief patterns help guide next steps, which may include additional injections, more targeted procedures, or non-surgical treatment strategies focused on the underlying condition.

Precision and Accuracy

IMAGE GUIDANCE & SAFETY

Image guidance allows the physician to:

Accurately target the intended nerve

Avoid surrounding structures

Confirm appropriate medication placement

This approach reflects modern best practices in interventional pain management.

FAQ'S

Frequently Asked Questions

Relief may be temporary and varies based on the type of block and underlying condition.

Most patients tolerate the procedure well. Local anesthetic is used to minimise discomfort.

It can serve either or both roles, depending on how it is used in your care plan.

Your response helps guide next steps, which may include additional injections or other treatments.
