Why Radiofrequency Ablation for Back Pain Could Be a Game-Changer
If you’re dealing with chronic back pain and have tried everything from physical therapy to medications with no long-term success, you’re not alone. I’ve been there too—multiple times. One day it’s a dull ache, the next it’s a sharp jab just trying to get out of the car. After months of trial and error, I discovered something that actually made a difference: radiofrequency ablation for back pain. It’s not magic, but it can feel pretty close when done right.
What Is Radiofrequency Ablation for Back Pain?
Radiofrequency ablation (RFA), also known as radiofrequency neurotomy, is a minimally invasive procedure that uses heat generated by radio waves to disrupt pain signals. It targets the medial branch nerves that carry pain from the facet joints in your spine. These joints, especially in the lower back, are common culprits in chronic pain, especially if you’ve been told you have arthritis or degenerative disc disease.
I first heard about RFA from a pain specialist after multiple steroid injections stopped working. I was skeptical—burning nerves to relieve pain sounded intense. But I did my research (probably too much), and found it’s a legit option backed by clinical studies and years of success stories. It’s even endorsed by spine organizations like Spine-health and Cleveland Clinic.
How the Procedure Works
Pre-Procedure: Diagnostic Nerve Block
Before you even qualify for RFA, your doctor will likely perform a diagnostic nerve block. They’ll inject a small amount of anesthetic near the medial branch nerves. If your pain drops by more than 50%, you’re a good candidate. Mine dropped by 80%—and let me tell you, that temporary relief felt like a miracle.
During the Procedure
You lie face down while your doctor uses fluoroscopy (a type of X-ray) to guide a thin needle to the targeted nerve. Then a small electrode sends radio waves that heat the tissue, effectively “shutting off” the nerve’s ability to send pain signals. The whole thing takes 30 to 90 minutes depending on how many nerves are treated.
Post-Procedure and Recovery
It’s an outpatient procedure, so you go home the same day. I had some soreness for about a week—like a deep bruise—but within a few weeks, my pain was significantly reduced. I went from barely walking more than 10 minutes to doing full grocery runs again.
Who’s a Good Candidate for RFA?
- People with chronic lower or upper back pain, especially from arthritis or facet joint issues
- Patients who’ve had short-term relief from medial branch blocks
- Individuals looking to avoid spinal surgery
- Those with conditions like degenerative disc disease or bulging discs
RFA isn’t for everyone. If your pain comes from muscular issues or herniated discs pressing directly on nerve roots, other treatments may be more effective. Check out this guide on symptoms and diagnosis to understand where your pain might be coming from.
Benefits of Radiofrequency Ablation
- Long-lasting pain relief: Results can last 6 months to over a year. Some get relief for even longer.
- Minimally invasive: No general anesthesia, no large incisions.
- Quick recovery: Most people return to light activities within a few days.
- Repeatable: If pain returns, the procedure can be safely repeated.
From my own experience, the biggest benefit was getting my life back. I could travel, sit through meetings, and even get back into light workouts. I wasn’t just managing pain—I was finally living again.
Risks and Side Effects
While RFA is generally safe, like any procedure, there are potential risks. These include:
- Soreness at the injection site
- Temporary numbness or tingling
- Rare nerve damage or infection
For me, the recovery was straightforward. A bit of stiffness and soreness, but nothing close to the original pain I had lived with for over two years. My specialist told me to expect minor discomfort and that was accurate. It’s nothing compared to the flare-ups I used to get from poor posture or long drives (like this article explains).
Complementary Treatments After RFA
To get the most from RFA, consider combining it with:
- Stretching and strengthening exercises
- Pilates or yoga for spinal mobility
- Physical therapy to improve body mechanics
- Anti-inflammatory diet (cut back on sugar and processed foods)
Here’s where I started seeing major gains. Once the pain was reduced, I could actually engage in the therapy I’d been avoiding. I highly recommend working with a PT who understands spine-specific rehab.

How Long Does Radiofrequency Ablation Last?
One of the first questions I had was: “How long will the relief actually last?” The answer is: it depends. Most people experience pain relief anywhere from 6 to 12 months, though I’ve read (and spoken to) folks who went 18 months or more before needing a repeat procedure. Personally, I was good for about 11 months. When the pain started creeping back, I booked a follow-up—my doctor said it’s totally safe to repeat as needed.
The reason it’s not permanent is because nerves regenerate over time. The goal is to give you a long enough window to work on lifestyle changes that address the root cause of your back pain—like posture, core strength, or fixing poor sitting habits.
What It Feels Like After RFA
I get this question all the time from friends: “Does it feel weird to have nerves burned off?” Honestly? Not at all. The sensation you lose is mostly pain—not mobility or touch. For the first week or two, I felt a dull soreness, and there was a bit of stiffness. But within three weeks, the sharp, stabbing pain I used to get just standing from a chair was gone.
Some people feel numbness around the treated area; others, like me, don’t notice much beyond pain relief. I kept waiting for something dramatic, but instead, it was more like, “Huh… I just walked up the stairs without flinching.” Quiet, subtle, and life-changing.
Does Insurance Cover Radiofrequency Ablation?
Yes, most insurance plans—including Medicare—cover RFA if you’ve gone through the diagnostic block process and conservative treatments first. I had to jump through some hoops: documentation, PT records, etc., but it was worth it. Out-of-pocket, the cost can range from $1,000 to $3,500 per session, depending on how many levels are treated. With insurance, my co-pay was around $250. Always check your plan and get pre-approval if needed.
Is It Better Than Other Treatments?
Radiofrequency ablation isn’t a silver bullet, but compared to other options, it checks a lot of boxes. Here’s how it stacks up:
- Steroid Injections: Quick relief, but wears off fast (1–3 months for me).
- Physical Therapy: Essential, but slow-going when you’re in severe pain.
- Medications: Helpful for managing symptoms, but come with side effects.
- Surgery: High risk, longer recovery, not always better outcomes.
If you’re not ready for surgery but exhausted from pills and needles, RFA is that sweet spot in the middle. It bridges the gap between conservative care and surgical intervention. That said, combining it with rehabilitation and ergonomics improves your odds of long-term success.
Things I Wish I Knew Before RFA
- The relief isn’t instant: It took me 2–3 weeks to feel the full effects.
- It’s not “numbing” the area: It’s disrupting pain signals at the source.
- You may need more than one level treated: Ask your provider about this during your consult.
- It’s worth prepping your body before: I did light PT leading up to the procedure, and my recovery was smoother.
It’s also not something you do casually. You’ll need a skilled pain specialist—ideally someone experienced in spine procedures. Mine used fluoroscopy and talked me through every step. If your doctor isn’t using imaging guidance, find another one.
When RFA Might Not Work
While RFA helps many, it’s not for everyone. Here’s when it may fall short:
- Your back pain isn’t facet-related (e.g. it stems from muscular imbalances or disc pressure)
- Your diagnostic block didn’t relieve your pain
- You have widespread, non-localized pain (think fibromyalgia)
That’s why the screening process is crucial. Your doctor may send you for MRI or X-rays to identify the source, or try multiple diagnostic injections. Don’t skip steps. I almost did—and would’ve wasted time and money.
What Comes After Radiofrequency Ablation?
For me, RFA was the turning point—but what came after mattered just as much. Once I had relief, I finally had the freedom to build a stronger foundation. I worked on:
- Improving my posture during long work sessions
- Using lumbar support while driving
- Practicing yoga for spinal mobility
- Strengthening my glutes and core
- Switching to an anti-inflammatory diet (less processed, more omega-3s)
Don’t underestimate the importance of lifestyle. I followed some of the tips from this lifestyle and natural remedies guide—and honestly, every small change added up.
Radiofrequency ablation gave me a fresh start. But it was the follow-through—exercise, posture, and consistency—that turned relief into long-term recovery.
