Chronic lower back pain is one of the most common reasons adults seek medical care. It is also one of the most frustrating conditions to treat. When pain lingers for months or years despite physical therapy, medications, or injections, patients often feel like they’ve run out of options.
Fortunately, there’s a powerful, non-surgical treatment that’s helping many people finally find relief: radiofrequency ablation (RFA). This minimally invasive procedure targets the nerves responsible for sending pain signals from the joints of the lower back to the brain, offering long-lasting results without the need for surgery or long recovery times.
At Pain & Vascular Institute, we specialize in advanced interventional treatments like RFA to help patients in greater Chicagoland get back to the activities and comfort they deserve.
What Causes Chronic Lower Back Pain?
Lower back pain can come from a variety of sources. In many cases, it’s caused by degeneration of the small joints in the spine, called the facet joints. These joints allow the spine to bend and twist but can become inflamed over time due to arthritis, overuse, injury, or age-related wear.
When the facet joints are irritated, they send pain signals through small nerves called the medial branch nerves. These nerves don’t control movement or strength, they exist solely to transmit pain. And that’s exactly what radiofrequency ablation is designed to address.
What Is Radiofrequency Ablation?
Radiofrequency ablation is a procedure that uses heat to interrupt pain signals from specific nerves. By applying a controlled dose of radiofrequency energy to the medial branch nerves, RFA stops those nerves from communicating with the brain. The result is significant, long-lasting pain relief for many patients.
This treatment is especially effective for people with:
- Chronic lower back pain due to arthritis or facet joint degeneration
- Pain that responds temporarily to facet joint injections
- No major disc herniation or instability requiring surgery
- Pain that worsens with twisting, arching the back, or prolonged standing
RFA does not “numb” the back or affect your ability to walk, move, or perform daily activities, it simply reduces the pain caused by irritated nerves.
How Does the Procedure Work?
Radiofrequency ablation is an outpatient procedure that takes about 30 to 60 minutes. It is typically done under light sedation or local anesthesia for comfort. Here’s what you can expect:
- Imaging guidance is used to place a thin needle near the targeted medial branch nerves.
- Once the needle is in place, a small amount of electrical stimulation helps confirm the location.
- Radiofrequency energy is delivered through the needle, generating heat that destroys the nerve.
- The process is repeated for each affected nerve pathway, typically on one or both sides of the spine.
Since the medial branch nerves don’t control movement or strength, destroying them doesn’t impair your physical function, it simply reduces pain transmission.
What Is Recovery Like?
Most patients are able to go home the same day and return to light activity within 24 to 48 hours. You may feel some soreness or muscle tightness for a few days at the procedure site, but this typically improves quickly.
Pain relief usually begins within 1 to 3 weeks after the procedure and can last 6 months to over a year, depending on the individual. Once the nerves grow back (which they eventually do), the procedure can be safely repeated if needed.
RFA offers a unique advantage: it allows patients to reduce or eliminate the use of daily pain medications and re-engage in physical activity, which is essential for long-term spine health.
Benefits of Radiofrequency Ablation
- Minimally invasive: No incisions, stitches, or general anesthesia
- Outpatient procedure: Go home the same day
- Quick recovery: Most patients return to daily routines within days
- Long-lasting relief: Pain relief can last 6–12 months or more
- Non-opioid solution: Reduces reliance on pain medications
- Improved mobility: Many patients can walk, bend, and move with less discomfort
Radiofrequency ablation is often the turning point for patients who have tried other treatments without success and want to avoid major surgery.
Is RFA Right for You?
At Pain & Vascular Institute, we take a careful, step-by-step approach to determine if RFA is appropriate. The process often begins with diagnostic medial branch blocks: a set of numbing injections placed in the same nerves targeted in RFA.
If your pain improves significantly after these blocks (even temporarily), it confirms that the medial branch nerves are involved. This diagnostic step helps ensure that RFA will be both safe and effective for your condition.
Ideal candidates for RFA typically:
- Have had chronic low back pain for 6 months or more
- Have responded well to facet joint injections or medial branch blocks
- Want to avoid spine surgery
- Have normal or mildly abnormal imaging (e.g., mild arthritis, no severe disc collapse)
- Are looking for a treatment with longer-lasting effects than steroid injections
