Nerve Blocks for Neck, Back & Head Pain
Targeted testing to uncover the source of pain—and guide you toward long-term relief.
Persistent neck or back pain, as well as occipital headaches, may originate from small joints in the spine known as facet joints. At Silver Pain Centre, we use diagnostic nerve blocks to accurately identify whether these joints are the source of your pain. This involves temporarily “blocking” the nerves with a local anesthetic to see if your pain improves.

What is a Nerve Block?
A nerve block is a minimally invasive procedure that involves injecting a local anesthetic near specific nerves to temporarily “block” pain signals from reaching the brain. At Silver Pain Centre, we use diagnostic nerve blocks to pinpoint the exact source of pain—most commonly from the facet joints in the neck, back, or spine.
These blocks are performed using image-guided precision (fluoroscopy or X-ray) to ensure safety and accuracy. If the nerve block significantly reduces your pain, it confirms that those nerves are the likely cause. This helps your physician decide if a more lasting treatment—like radiofrequency neurotomy—is appropriate.
Nerve Blocks May Help Identify the Source of:
Chronic neck or lower back pain
Occipital headaches (base of skull)
Facet joint pain aggravated by movement
Pain persisting after spinal surgery or injury
Pain unresponsive to physical therapy or medications
How the Procedure Works
At Silver Pain Centre, diagnostic nerve blocks are performed in-office by experienced specialists using sterile, image-guided techniques to ensure safety and precision.
Step-by-Step Process:
Positioning
You’ll lie on your stomach while we prepare the treatment area for injection.
Needle Placement
Using X-ray (fluoroscopic) guidance, small needles are inserted near the tiny nerves that supply your facet joints—typically in the neck or lower back.
Anesthetic Injection
A small amount of local anesthetic is injected through each needle to temporarily block the targeted nerves.
Monitoring Response
You’ll remain awake during the procedure so you can help assess whether your pain improves. This feedback helps confirm if the facet joints are the true source of your pain.
Repeat Test (if needed)
Because this is a diagnostic procedure, it may be repeated once more for accuracy before considering a longer-lasting option like radiofrequency neurotomy.
The procedure typically takes 15–30 minutes, and patients return home the same day.

Frequently Asked Questions
How Long Does Relief Last?
-
Diagnostic nerve blocks provide temporary pain relief, typically lasting several hours up to a day, depending on the local anesthetic used.
-
These injections are designed to confirm whether your pain originates from the facet joints—they are not intended to provide long-term relief.
-
If significant pain relief occurs after the block, it indicates that a longer-lasting treatment like radiofrequency neurotomy may be appropriate.
-
For accuracy, the block may be repeated once to confirm the diagnosis before proceeding to next steps.
Is This Treatment Right for You?
Nerve blocks are most effective for patients with:
-
Chronic neck or back pain that hasn’t responded to medication or physical therapy
-
Occipital headaches starting from the base of the skull
-
Pain that worsens with movement, prolonged sitting, or standing
-
Pain possibly originating from facet joints in the spine
-
A need for diagnostic clarity before considering longer-lasting treatments
If your pain improves significantly after the block, it confirms the affected nerves as the source—helping your physician build a more targeted treatment plan.
