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.
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.
Temporarily reducing pain signals
Identifying the specific nerve contributing to pain
Improving function and tolerance for activity
Guiding further treatment decisions
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.
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
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:
Patient Positioning
Patients are positioned to allow precise access to the intended nerve pathway
Local Anesthesia
The skin is cleaned and numbed with a local anesthetic.
Image Guidance
Fluoroscopy or ultrasound guidance is used to identify the correct nerve location
Targeted Injection
Medication is carefully delivered adjacent to the nerve
Recovery Monitoring
Patients are monitored briefly before discharge.
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
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.
PHYSICIAN EXPERTISE
All nerve blocks at Motionis Medicine are performed by Dr. Tanuj Palvia, MD, a board-certified interventional pain medicine physician with advanced training in image-guided spine and nerve procedures.
Dr. Palvia personally evaluates each patient and determines whether a nerve block is appropriate as part of a comprehensive, non-surgical care plan.
What Outcomes Can Patients Expect?
Response to nerve blocks varies depending on the condition and individual factors. Patients may experience:
Temporary pain relief lasting hours to weeks
Improved understanding of pain source
Guidance for future treatment options
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.
Schedule a Pain Evaluation
If nerve-related pain is affecting your daily life, a comprehensive evaluation can help determine whether a nerve block is appropriate.
