Nerve Block Injections

Selective nerve root block (SNRB) injections are commonly used for pain from a compressed spinal nerve root. Placed precisely next to one nerve, they can confirm which nerve is causing the pain and reduce inflammation to relieve it, often enough to begin physical therapy or avoid surgery.

What Are Nerve Block Injections?

Selective nerve root block injections are used to diagnose and treat neck and back pain. They target specific nerve roots to help identify the source of pain or provide relief, using imaging guidance to deliver the injection accurately.
 
Depending on the condition, injections may be given in the cervical (upper), thoracic (middle), or lumbar (lower) spine. They are often used for radiculopathy, when pain travels along a single nerve into an arm or leg.

Conditions Nerve Blocks Treat

When And Why Nerve Blocks Are Used

Diagnosis: to pinpoint the source of pain, an anesthetic nerve block is placed at a specific nerve. If the pain subsides temporarily, it confirms that nerve as the cause, which can also help predict whether surgery might be effective.
 
Treatment: corticosteroid-based nerve blocks reduce inflammation and pain, which can provide enough relief for patients to begin physical therapy or manage symptoms without surgery.

Understanding The Nerve Block Process

A nerve block is a short outpatient procedure:

  1. 1

    Preparation

    The injection site is cleaned and numbed.

  2. 2

    Imaging guidance

    Fluoroscopy or ultrasound guides the needle to the specific nerve root.

  3. 3

    Injection

    An anesthetic, with or without a corticosteroid, is placed next to the nerve.

  4. 4

    Assessment

    Your pain response is recorded to guide diagnosis and treatment.

Frequently Asked Questions

What is a selective nerve root block?

A selective nerve root block (SNRB) is an injection placed next to a specific spinal nerve root to diagnose or treat pain from that nerve.

How does a nerve block help with diagnosis?

An anesthetic is placed at a specific nerve root. If the pain subsides temporarily, it confirms that nerve is the cause, which can also help predict whether surgery might be effective.

How does a nerve block help with treatment?

Corticosteroid-based nerve blocks reduce inflammation and pain, which may provide enough relief to begin physical therapy or manage symptoms without surgery.

How many injections will I need?

One injection may be enough, while some patients need more than one. Your physician will recommend a plan based on how you respond.

Where can nerve blocks be given?

Depending on the condition, injections may be given in the cervical (neck), thoracic (mid back), or lumbar (lower back) spine.

Is imaging used?

Yes. Imaging guidance is used to deliver the injection accurately to the affected nerve root.

What conditions are treated with nerve blocks?

Pain from a compressed spinal nerve root, such as from a herniated disc, foraminal stenosis, or spinal stenosis, including sciatica and cervical radiculopathy.

How do I find out if a nerve block is right for me?

An evaluation and imaging review will determine whether a nerve block can help pinpoint or treat your pain. Call (321) 499-4646.

Benefits Of Nerve Blocks

Nerve block injections offer:

  • Precise diagnosis of which nerve is causing pain.
  • Targeted relief of inflammation at the nerve root.
  • A window for physical therapy with less pain.
  • A possible alternative to surgery for some patients.
  • An outpatient procedure with a quick return home.
