Radiofrequency ablation vs. steroid injections for chronic pain
Quick answer: Both radiofrequency ablation and steroid injections are minimally invasive treatments for chronic pain, but they work differently. Steroid injections reduce inflammation for short-term relief (weeks to months), while radiofrequency ablation disrupts pain signals at the nerve level for longer-lasting results (6–24 months). The right choice depends on your diagnosis, pain type, and treatment goals.
Chronic pain doesn't just hurt—it changes the way you live. It limits the activities you love, affects your sleep, and can quietly erode your quality of life over time. When over-the-counter medications stop working and rest doesn't seem to help, minimally invasive procedures like radiofrequency ablation (RFA) and steroid injections are two of the most effective next steps.
At DFW Interventional Pain Institute, we help patients across the DFW metroplex understand their options and choose the right treatment for their specific condition. Both procedures can significantly reduce pain—but they're not interchangeable. Knowing how each one works, and when to use it, can make a real difference in your outcome.
What is chronic pain, and who does it affect?
Chronic pain is defined as pain that persists for six months or longer, often beyond the expected time of healing. It can stem from an injury, a degenerative condition, nerve damage, or inflammation—and it affects an estimated 60 million adults in the United States, according to the CDC.
The conditions we most commonly treat with these procedures include back pain, neck pain, arthritis, sciatica, facet joint syndrome, and shoulder pain. For many patients, the pain is constant. For others, it flares unpredictably. Either way, living with it isn't something you have to accept as the new normal.
How does radiofrequency ablation work to reduce pain signals?
Radiofrequency ablation is a procedure that uses heat generated by radio waves to damage specific nerve fibers that carry pain signals to the brain. By interrupting this transmission, RFA can provide substantial relief—often lasting anywhere from 6 to 24 months.
During the procedure, a thin needle is guided to the target nerve using imaging technology. A small electrode delivers radiofrequency energy to heat the surrounding tissue, effectively "turning off" the nerve's ability to send pain signals. The procedure typically takes less than an hour, and most patients are able to return to light activity within a few days.
RFA tends to work best for facet joint pain, arthritis-related back and neck pain, and other conditions where a specific nerve pathway can be clearly identified as the pain source. It's not a permanent fix—nerves can regenerate over time—but many patients find that they can repeat the procedure when symptoms return.
How do steroid injections work to reduce inflammation?
Steroid injections deliver corticosteroids—powerful anti-inflammatory medications—directly to the site of pain. The goal is to reduce inflammation in and around the affected area, which relieves pressure on surrounding nerves and tissues.
Depending on the location and cause of your pain, steroid injections can be administered into joints, the epidural space of the spine, around nerve roots, or into soft tissue. The procedure is quick and typically performed with imaging guidance for precision.
Relief from steroid injections can begin within a few days and may last anywhere from several weeks to several months. They're particularly effective for conditions driven by acute inflammation—such as herniated discs, bursitis, and inflammatory arthritis. Some patients use steroid injections as a bridge while pursuing other therapies, such as physical therapy or rehabilitation.
Radiofrequency ablation vs. steroid injections: what are the key differences?
Choosing between these two treatments comes down to the nature of your pain, how long you need relief, and how your body has responded to previous treatments. Here's a direct comparison:
How long does pain relief last with each treatment?
Steroid injections typically provide relief for several weeks to a few months. Radiofrequency ablation tends to last significantly longer—often 6 to 24 months—making it a better fit for patients who need sustained, long-term relief.
Which conditions does each treatment work best for?
Steroid injections are most effective when inflammation is the primary driver of pain. RFA is better suited to conditions where a specific nerve pathway is responsible for transmitting chronic pain, particularly in the facet joints of the spine or sacroiliac joints.
What's the recovery time and are there side effects?
Both procedures are minimally invasive with relatively short recovery windows. With steroid injections, you might experience mild soreness at the injection site for a day or two. With RFA, some patients experience temporary numbness or a brief increase in discomfort as the nerve responds to the procedure—but this typically resolves within a week or two.
One important consideration with steroid injections is frequency. Repeated corticosteroid use can have systemic effects, so most physicians limit the number of injections per year.
What about cost and insurance coverage?
Both radiofrequency ablation and steroid injections are widely covered by insurance when medically necessary. However, coverage details vary by plan, and prior authorization is often required. Our team can help you navigate the process and understand your options before moving forward.
When should you see a pain specialist instead of your primary care doctor?
Primary care physicians are a great first stop for pain that's new or mild. But if your pain has lasted more than a few weeks, is getting worse, or is interfering with your daily life, it's time to see a specialist.
Some specific signs you shouldn't ignore:
Pain that radiates down your arm or leg
Numbness, tingling, or weakness in your limbs
Pain that doesn't respond to medication or rest
Worsening symptoms despite conservative treatment
A pain management specialist has the training and tools to accurately diagnose the source of complex pain—and to recommend procedures that a general practitioner may not offer. The earlier you get a proper evaluation, the better your chances of avoiding more invasive interventions down the line.

Frequently asked questions
What's the difference between radiofrequency ablation and steroid injections?
Steroid injections reduce inflammation at a specific site and typically provide relief for several weeks to months. Radiofrequency ablation uses heat to interrupt pain signals carried by specific nerves, often providing relief for 6 to 24 months. Both are minimally invasive—but they treat different aspects of chronic pain.
Is radiofrequency ablation better than steroid injections for long-term pain relief?
For patients with nerve-mediated chronic pain, such as facet joint arthritis or sacroiliac joint dysfunction, radiofrequency ablation generally offers longer-lasting results than steroid injections. However, steroid injections may be the better first-line option when inflammation is the primary cause of pain.
How many steroid injections can you have per year?
Most physicians limit corticosteroid injections to three or four per year in a single area to minimize the risk of systemic side effects such as bone density loss or hormonal changes. Your pain specialist can help determine the appropriate frequency based on your condition.
Does insurance cover radiofrequency ablation or steroid injections?
Both procedures are commonly covered by insurance when deemed medically necessary. Coverage varies by plan, and prior authorization may be required. It's best to confirm your benefits with your insurance provider before scheduling.
How do I know which treatment is right for me?
The right treatment depends on your diagnosis, the source and nature of your pain, and your treatment history. A thorough evaluation by an interventional pain specialist—including a physical exam, imaging review, and discussion of your goals—is the most reliable way to determine the best approach for your specific situation.
