Medial Branch Blocks: A Diagnostic Step for Facet Joint Pain
Sometimes the test is part of the answer
Medial branch blocks are used to help determine whether small spinal joints called facet joints are contributing to back or neck pain. They are diagnostic tools, not magic wands — although a clear answer can feel pretty magical when pain has been confusing.
Patients across New Hampshire, Southern Maine, and Massachusetts may hear about these blocks when pain is localized, movement-related, and persistent.
Why this matters
Facet joints are supplied by medial branch nerves. Temporarily numbing those nerves can help clarify whether the facet joints are a likely pain source.
Symptoms worth tracking
- Back or neck pain worse with extension or twisting
- Localized aching near the spine
- Pain with standing or walking
- Stiffness after rest
- Temporary relief after diagnostic injection
How a pain specialist thinks through it
A specialist reviews history, exam findings, imaging, and symptom behavior before deciding whether diagnostic blocks are appropriate.
Treatment options are individualized
If blocks provide meaningful temporary relief, radiofrequency ablation may be discussed for selected patients. If not, the search for the pain source continues.
The value is in using the response to guide decisions, not in treating every imaging finding.
PSG perspective
PSG uses diagnostic reasoning to avoid one-size-fits-all spine care.
