Radiofrequency Ablation (RFA) for Back Pain
What is it?
A simple, effective treatment for pain coming from the facet joints of the spine.
What are facet joints and why do they hurt?
Your spine is made up of small bones (vertebrae). Between them are facet joints, which help your back bend and twist. Over time, these joints can become irritated due to:
• Arthritis or wear and tear Injury or strain Poor posture or repetitive movements
• This can lead to localized back pain, usually in the lower back (lumbar spine), Mid-back (thoracic spine), and Neck (Cervical spine).
Facet pain is often worse when you lean backward, twist, or stand for long periods.
What is Radiofrequency Ablation (RFA)?
Radiofrequency ablation is a minimally invasive procedure that reduces pain by turning off the small nerves that carry pain signals from the facet joints.
Using a special needle and X-ray guidance, your doctor delivers gentle heat to these nerves, stopping them from sending pain messages to your brain.
Who is a good candidate?
You may benefit from RFA if:
• You have chronic back pain lasting more than 3–6 months
• Your pain is coming from the facet joints
• You experienced good relief from a diagnostic numbing injection (test block)
What happens during the procedure?
• Performed in an outpatient setting (you go home the same day)
• You lie comfortably while the area is numbed
• A small needle is guided to the target nerves using X-ray
• Heat is applied for about a minute to each nerve
Total time: about 30–60 minutes
You may feel some pressure, but most patients tolerate it very well.
What can I expect afterward?
• Mild soreness for a few days is normal
• Pain relief usually starts within 1–3 weeks
• Many patients experience significant pain reduction
Relief typically lasts 6 to 18 months, and the procedure can be repeated if needed.
Benefits of RFA
• Long-lasting pain relief
• No surgery required
• Reduced need for pain medications
• Improved ability to move and stay active
Are there any risks?
RFA is considered very safe, but possible side effects include:
• Temporary soreness or swelling
• Numbness or tingling near the treatment area
• Rarely, infection or bleeding
Your doctor will review all risks with you before the procedure.
When might RFA not help?
RFA works best for facet joint pain. It may not be effective if your pain is caused by:
• A herniated disc (sciatica)
• Severe spinal stenosis
• Widespread pain conditions
Ready to take the next step?
If you’ve been living with persistent back pain, RFA may help you get back to your daily activities with less discomfort. Talk to your doctor to see if this treatment is right for you.
