Facet Joint Pain: How It's Diagnosed and Treated in Napa

Quick Insights:
Facet joint pain is a common, often underdiagnosed cause of chronic low back pain that originates from the small paired joints connecting each vertebra in the spine. Research suggests that accurate diagnosis depends on a combination of clinical evaluation and image-guided diagnostic medial branch blocks, because imaging alone cannot confirm that arthritic-looking joints are the actual pain generator. When facet-mediated pain is confirmed, evidence indicates that radiofrequency ablation can offer durable relief for carefully selected patients.
Key Takeaways
- Facet joints are small stabilizing joints in the spine that can become painful from arthritis, repetitive strain, or age-related wear.
- Studies indicate that diagnostic medial branch blocks are the most reliable way to confirm whether your facet joints are the true source of back pain.
- Research suggests that radiofrequency ablation can provide many months of meaningful pain relief by interrupting pain signals from confirmed facet joints.
- Treatment decisions depend on accurate diagnosis, your symptom pattern, and how you respond to diagnostic procedures, not on imaging findings alone.
Why It Matters:
Chronic low back pain has a way of shrinking your world. The hike you used to look forward to, the harvest-season shift you used to power through, the simple act of standing through a long dinner with family, all of it gets harder when your back is the loudest thing in the room. When that pain comes from your facet joints, the answer is rarely "live with it." Pinpointing the source through diagnostic medial branch blocks opens the door to targeted, minimally invasive treatment that can give you back the activities that matter most to you.
Understanding Facet Joint Pain: Diagnosis and Treatment Options
I'm Jackie Weisbein, DO, a fellowship-trained interventional pain specialist, and a big part of what I do, every single week here in Napa, is help patients figure out where their back pain is actually coming from. So many people arrive in my office having been told, "It's just arthritis, learn to live with it." That answer never sits right with me, and it shouldn't sit right with you either. Facet joint pain is one of the most common, and most overlooked, contributors to chronic low back pain. The good news: when we can confirm the facet joints are the culprit, modern research supports evidence-based, minimally invasive options that can offer meaningful relief.
In this article, I'll walk you through what facet joints are, how I diagnose facet-mediated pain in my practice, and what the research says about modern treatment options, including radiofrequency ablation.
Important Safety Information
Interventional facet procedures are generally safe when performed by a fellowship-trained interventional pain physician under image guidance. That said, every procedure carries some risk. Before any diagnostic block or radiofrequency procedure, I review all medications (especially blood thinners), allergies, and underlying medical conditions. Small risks include bleeding at the needle site, infection, and rare nerve irritation. Patients with active infections, uncontrolled bleeding disorders, pregnancy, or implanted electrical devices such as pacemakers should let me know in advance so we can plan accordingly. We'll talk through every step before anything is scheduled.
What Are Facet Joints and Why Do They Cause Pain?
Your spine has a pair of small facet joints at every level, one on each side, connecting one vertebra to the next. They are about the size of a fingernail. Think of them like the hinges on a door, they guide and limit how your spine bends and twists while keeping everything stable. Like every other joint in your body, they have cartilage, a lubricated capsule, and a dense supply of pain-sensing nerves.
When those joints wear down, get inflamed, or are injured, those nerves light up. Common drivers include osteoarthritis, repetitive bending and twisting (think years of vineyard work, gardening, or heavy lifting), prior injuries, and the slow accumulation of age-related changes. Patients often ask me, "Why now?" The honest answer is that facet joints can be quietly degenerating for years before they decide to make themselves heard.
Facet pain usually feels like a deep, aching pressure along the midline of your lower back. It tends to get worse when you arch backward, twist, or stand for long periods. It can refer into the buttocks or the back of the thighs, but rarely below the knee, which helps us distinguish it from nerve-root pain like sciatica.
Here's a critical point that surprises a lot of patients: arthritic-looking facet joints on your MRI do not automatically mean your facet joints are the pain source. In a scoping review across 37 studies, imaging findings alone were not reliable predictors of who would benefit from facet interventions, while clinical pattern, pain duration, and confirmatory diagnostic work were. That's why I take history, exam, and diagnostic blocks just as seriously as imaging.
How Facet Joint Pain Is Diagnosed
Clinical Evaluation and Physical Examination
It always starts with a thorough conversation. I want to know where your pain lives, what makes it better, what makes it worse, and how it's reshaping your day-to-day life. On exam, I'll look at your posture, your range of motion, and how you move. I'll use targeted maneuvers, especially extension combined with rotation, that load the facet joints specifically. If those movements reproduce your pain pattern, my suspicion for facet involvement goes up. But clinical exam is a clue, not a verdict.
Diagnostic Medial Branch Blocks
This is where we move from "suspicion" to "confirmation." Diagnostic medial branch blocks are widely considered the most reliable way to identify facet-mediated pain. Here's how I think about them, and this is one of my favorite analogies to share with patients: a diagnostic block is like a detective looking for the source of a fire alarm, not just silencing the alarm itself. By temporarily numbing the small nerves (medial branches) that carry signals from a specific facet joint, we get a clear answer: if your pain quiets down significantly during the anesthetic's window, those joints are speaking.
A landmark randomized double-blind trial of lumbar facet joint nerve blocks followed patients for two years and found that, in those whose pain was confirmed via diagnostic blocks, therapeutic medial branch blocks produced significant pain relief and meaningful functional improvement in the large majority of patients, with about 82 to 84 weeks of significant relief over a 2-year follow-up. That kind of durability is one reason I lean so heavily on confirmatory blocks before recommending longer-acting treatments.
The Role of Imaging
X-rays, CT, and MRI are valuable, but mostly for ruling things out: fracture, tumor, infection, nerve-root compression, anything that needs a different treatment path. They also help me plan needle trajectories during procedures. What imaging cannot do is tell us whether the arthritic-looking joint on your scan is actually the pain generator. The diagnosis of facet-mediated pain is functional, not anatomical. That distinction shapes every recommendation I make.
Evidence-Based Treatment Options for Facet Joint Pain
Most patients with facet pain do not need anything dramatic, at least not at first. I almost always start with conservative care: targeted physical therapy emphasizing core stability and hip mobility, postural retraining, short courses of anti-inflammatories when appropriate, activity modification, and weight management if it's a contributor. For many patients, that's enough.
When conservative care plateaus and diagnostic blocks confirm a facet source, the next step is often radiofrequency ablation (RFA). RFA uses precise, image-guided heat to gently lesion the small medial branch nerves that carry pain signals from the affected facet joints. Think of it like turning the volume way down on a noisy speaker, the joint itself is unchanged, but the signal it can send to your brain is reduced.
A 2021 systematic review and meta-analysis of radiofrequency neurotomy pooled twelve randomized trials and reported Level II evidence supporting RFA's efficacy for pain reduction and functional improvement in patients whose facet pain was confirmed through diagnostic blocks. To present a fair picture, the evidence is not unanimous: an older sham-controlled trial did not separate radiofrequency from sham on its primary combined outcome, although secondary measures favored the active procedure. The modern reading of that and similar trials is that patient selection (specifically, using high-quality diagnostic blocks before committing to RFA) is what separates the trials with strong outcomes from the ones with mixed results. That's exactly why I'm meticulous about diagnostics first.
For some patients, comprehensive back pain treatment also includes therapeutic facet joint steroid injections, which can reduce inflammation in the joint itself, and complementary therapies like physical therapy. RFA is not a cure, and I'm always careful to say so. It's a meaningful, repeatable reduction in pain signals from a confirmed source, often lasting many months, which can buy you the function you need to stay active.
Facet Joint Pain Treatment for Napa Valley Residents
Wine Country is a wonderful place to live an active life, and a tough place to nurse a chronic back. I see patients who manage vineyards, work in hospitality, raise families, hike Skyline Wilderness, ride the Vine Trail, and refuse to slow down quietly. Chronic facet pain affects more than just movement. It affects sleep, mood, work, and the small daily pleasures that make life here special.
The good news: you don't need to drive to San Francisco or Sacramento for advanced interventional pain care. As a fellowship-trained interventional pain specialist who has performed thousands of procedures over a decade and a half, I offer the full continuum of facet-focused care, from diagnostic spinal injection procedures to radiofrequency ablation, right here at Napa Valley Orthopaedic Medical Group. Working alongside community resources like Providence Queen of the Valley Medical Center, we keep your specialty care close to home.
I also know that the patients who travel to my office from across Wine Country are juggling a lot to get here. We respect your time, your goals, and the fact that you'd rather be doing almost anything else than sitting in a doctor's office.
When Should You Consider Facet Joint Evaluation?
I hear this from patients all the time: "I figured it was just my age." Maybe. Maybe not. Consider asking about a facet evaluation if any of the following sound familiar:
Signs Your Pain May Be Facet-Mediated
Lower back pain that has been around for more than three months and hasn't meaningfully improved with physical therapy, medication, or chiropractic care.
Pain that gets worse when you arch backward, twist, or stand for long stretches.
Localized low-back pain with little or no shooting leg pain below the knee.
Pain that is genuinely limiting your work, sleep, exercise, or family life.
You're not weak for asking for help, and you're not exaggerating. Chronic pain is exhausting, physically and emotionally. Together, we'll work through what's actually driving your pain and build a treatment plan that fits your life, not a generic protocol.
What to Expect During Your Visit
Your first visit is mostly a conversation, with a careful exam woven in. I want to understand your pain story, your prior treatments, what's worked and what hasn't, and what you want your life to look like a year from now. We'll review your imaging together; I'll explain what each finding means and, just as importantly, what it doesn't mean.
If facet pain looks likely, I'll explain the diagnostic block plan in plain language and answer every question you have. The block itself is an outpatient procedure performed under fluoroscopic image guidance. It typically takes 15 to 30 minutes. You go home the same day and track how much your usual pain quiets down over the next few hours, which is the data we use to decide on the next step.
If the diagnostic block is positive, we sit down again and talk through whether radiofrequency ablation makes sense for you. The procedure itself is also outpatient, also same-day, with most patients returning to light activity within a few days. I'll never push you. My job is to lay out the options honestly and help you make the decision that's right for your body and your life.
Comparing Treatment Approaches
| Aspect | Interventional Diagnosis + RFA | Conservative Care with Medication and Therapy |
|---|---|---|
| Diagnostic approach | Confirms the specific facet joints generating pain via diagnostic medial branch blocks | Clinical evaluation and imaging; the pain source is inferred from history and exam |
| Mechanism | Reduces pain signals from confirmed facet joints through targeted radiofrequency lesioning of medial branch nerves | Reduces inflammation, builds strength, and improves mechanics with PT, posture work, and medications |
| Typical duration of relief | Often many months; repeatable if pain returns (one trial reported around 82 to 84 weeks of significant relief across a 2-year window with therapeutic blocks) | Variable; often requires ongoing therapy and lifestyle work |
| Invasiveness | Minimally invasive, image-guided outpatient procedure | Non-procedural |
| Best for | Patients with diagnostically confirmed facet pain who haven't responded adequately to conservative care | First-line for most patients with new or moderate back pain |
| Recovery | Same-day procedure; light activity within days | No procedural recovery; ongoing participation in therapy |

When I evaluate a new patient with chronic low back pain, the goal is always the same: get to the actual source, then build a plan around it.
"Dr. Weisbein was able to diagnose what was causing my back pain and spasm and proposed how to alleviate it. It was all in all an extremely positive interaction."

What Jill describes is exactly the goal: a clear diagnosis and an honest, customized plan. That's the experience I work hard to deliver to every patient.
Taking the Next Step Toward Back Pain Relief
Facet joint pain is common, treatable, and frequently misdiagnosed as "just arthritis." The clinical work that separates good outcomes from disappointing ones is the diagnostic work: confirming the pain source through medial branch blocks before committing to longer-term treatment. When the facet joints are confirmed as the driver, evidence supports radiofrequency ablation as a durable, minimally invasive option for the right patient.
If you've been told there's nothing more to try for your low back pain, I'd love to take a fresh look. I schedule a consultation for patients across Napa Valley and the surrounding Wine Country every week, and I welcome you to do the same. Individual outcomes vary, and your plan will be built around your anatomy, your pain pattern, and your goals.
