Persistent neck or low back pain that worsens with bending, twisting, or standing may originate from the facet joints. When conservative treatments are no longer effective, radiofrequency ablation (RFA) of the medial branch nerves can offer longer-lasting relief without open surgery.
At Regional Brain & Spine, interventional pain specialists and physical medicine teams work together to confirm the diagnosis, perform precise procedures, and guide recovery.
How Medial Branch Radiofrequency Ablation Works
Facet joints are small stabilizing joints along the spine. Medial branch nerves transmit pain signals from these joints to the brain. RFA uses controlled heat delivered through a thin needle to interrupt those signals.
Importantly:
- The joint itself is not altered
- The spinal cord is not involved
- Only the targeted pain pathway is addressed
Before RFA is considered, patients undergo two diagnostic medial branch blocks. If temporary numbing of the nerve produces clear pain relief, it confirms the facet joint as the likely pain source.

Who May Be a Good Candidate
RFA is typically considered when pain patterns and testing align clearly with facet-mediated pain.
Common indicators include:
- Predominantly neck or low back pain without significant arm or leg symptoms
- Pain worsened by extension or rotation
- Imaging and physical exam findings consistent with facet involvement
- Two positive diagnostic medial branch blocks
Your overall health, daily demands, and response to conservative care are also factored into decision-making.
What to Expect on Procedure Day
RFA is performed as an outpatient procedure using live X-ray guidance.
The process generally includes:
- Review of imaging, medications, and consent
- Local anesthesia with optional light sedation
- Precise needle placement confirmed by test stimulation
- Controlled heating of the targeted nerve for a short duration
Most patients go home the same day and resume light activity within 24 hours.

Recovery and Rehabilitation After RFA
Temporary soreness is common for several days following the procedure. Ice, gentle movement, and over-the-counter medications (when appropriate) usually provide relief.
Pain improvement often becomes noticeable within 1–3 weeks, and outcomes are best when patients use this period to rebuild strength and mobility.
Rehabilitation typically focuses on:
- Gradual walking and daily movement
- Core stabilization and posture training
- Hip and thoracic mobility
- Ergonomic adjustments at work and home

How Long Relief Lasts and Repeat Treatment
Relief from RFA commonly lasts 6–12 months, and some patients experience benefit for up to two years. Over time, the treated nerves may regenerate, allowing pain to return.
RFA can be repeated when:
- Pain recurs
- Diagnostic criteria are again met
- Insurance timing requirements are satisfied
Your physician will tailor timing based on your response and goals.
Risks and Considerations
RFA is generally well tolerated, but potential downsides include temporary soreness, localized numbness, or incomplete relief. Rare complications include infection, bleeding, or nerve irritation.
Because nerves can regenerate, results are not permanent. Ongoing rehabilitation plays an important role in maintaining benefit.
Insurance Coverage
Medicare and many commercial plans cover RFA when medical necessity is documented. This typically includes failure of conservative care and positive diagnostic nerve blocks. Coverage and out-of-pocket costs are verified before scheduling.
Coordinated Care at Regional Brain & Spine
Interventional pain physicians perform image-guided procedures, while PM&R specialists guide rehabilitation and long-term movement strategies. If symptoms suggest another pain generator, treatment plans are adjusted conservatively and thoughtfully.
Next Steps
If chronic neck or back pain is limiting your daily life, a focused evaluation can help determine whether facet joints are contributing. Regional Brain & Spine offers diagnostic testing, minimally invasive treatment options, and structured follow-up designed to support lasting improvement.
Frequently Asked Questions
Is radiofrequency ablation considered surgery?
No. RFA is a minimally invasive, needle-based outpatient procedure without open incisions.
How long does it take to recover from RFA?
Most patients return to light activity within a day and experience improvement over one to three weeks.
How successful is RFA for facet pain?
When patients are carefully selected using diagnostic blocks, many experience meaningful pain reduction and improved function.
Can RFA be repeated?
Yes. The procedure can be safely repeated if pain returns and criteria are met.
Is RFA covered by insurance?
Most plans cover RFA when medical necessity and diagnostic requirements are documented.
