If you have been dealing with lower back pain that just will not go away, you have probably tried more than a few things. You stretched, rested, took medication, maybe even went through physical therapy. And yet the pain keeps coming back. At that point, a doctor may bring up a facet joint injection, and the first question most people ask is a very reasonable one: is this actually right for me?
That is exactly what this article answers. Facet joint injections are one of the most commonly performed spinal procedures, and when used for the right patients, they can provide meaningful relief from chronic lower back pain. But they are not the right solution for everyone. Understanding who benefits, what the signs are, and what the facet joint injections success rate looks like will help you walk into your next appointment with much clearer expectations.
What Is a Facet Joint and Why Does It Hurt?
Facet joints are small paired joints located along the back of the spine between each vertebra. They connect the bones of your spine, allow it to bend, twist, and rotate, and keep movement controlled and stable. Like any joint in the body, they contain cartilage and synovial fluid. And like any joint, they can degenerate over time.
When the cartilage inside a facet joint breaks down, the joint becomes inflamed, the surrounding tissue gets irritated, and pain signals travel through the small medial branch nerves up to the brain. This is known as facet joint syndrome or facet arthropathy, and it is far more common than most people realise.
According to StatPearls (NCBI, 2025), chronic low back pain results from facet joint disease in 15 to 45 percent of cases. Research from HealthCentral puts the range even higher, with some studies estimating facet joint syndrome accounts for up to 59.6 percent of lower back pain cases in men and 66.7 percent in women.
The most common location is the lumbar spine, particularly the L4-L5 and L5-S1 levels, which bear the most mechanical load from daily activity.
What Does Facet Joint Pain Feel Like?
Before deciding whether a facet joint injection is the right path, it helps to understand the typical symptoms of facet joint pain. These overlap with other back conditions, which is one reason facet issues often go undiagnosed for a long time.
Common signs that your pain may be coming from the facet joints include:
- A dull, aching pain in the lower back that is difficult to pinpoint exactly
- Pain that spreads to the buttocks, hips, or upper thighs but generally does not go below the knee (pain below the knee more often points to a disc issue)
- Stiffness and difficulty standing up straight, especially in the morning or after sitting for a long period
- Pain that worsens when leaning backward or twisting sideways toward the affected joint
- Relief when sitting, leaning slightly forward, or changing positions
- Tenderness when pressure is applied over the affected spinal area
- A grinding or grating sensation in the lower back during movement
If you recognise several of these symptoms and they have persisted for more than three months without adequate relief from conservative treatment, facet joint injections for lower back pain may be worth discussing with a specialist.
Who Is a Good Candidate for a Facet Joint Injection?
A facet joint injection works best for a specific type of patient. The Hospital for Special Surgery (HSS) notes that for the right patients with confirmed facet involvement on imaging, success rates can be as high as 80 percent.
You are likely a good candidate if:
- Your pain is primarily axial, meaning it stays in the lower back, neck, or mid-back, rather than radiating sharply down the leg or arm
- Imaging such as an X-ray or MRI shows evidence of facet joint degeneration or arthropathy
- You have not found adequate relief after at least three months of conservative care, including physical therapy, anti-inflammatory medications, or activity modification
- Your pain is worse with spinal extension and rotation, the mechanical pattern typical of facet joint involvement
- A doctor suspects the facet joint as the source of your pain based on your symptoms and physical examination
Facet joint injections are also used in patients who experience pain after spinal fusion surgery, where adjacent segment degeneration can cause new facet-related pain.
Who Is Not the Right Candidate?
Being honest about who does not benefit from facet joint injections is just as important. This procedure is not the right choice for everyone with back pain.
You may not be a suitable candidate if:
- Your main symptom is leg pain or arm pain with little to no back or neck pain. This pattern suggests nerve compression from a herniated disc or spinal stenosis rather than facet joint involvement.
- Imaging shows a structurally normal spine with no evidence of facet degeneration
- You have an active infection, either in the body or at the proposed injection site
- You are on blood thinners and cannot safely pause them before a procedure (discuss this with your doctor, as some cases can be managed)
- You are pregnant
- You have a confirmed allergy to corticosteroids or local anesthetics used in the injection
According to StatPearls (NCBI), there are no absolute contraindications to facet joint injections other than patient refusal. The factors listed above are relative considerations that require proper clinical judgment, which is why an evaluation by a qualified specialist before proceeding is essential.
Facet Joint Injections for Lower Back Pain: What Actually Happens
If you and your doctor decide a facet joint injection is appropriate, understanding the procedure itself helps set clear expectations.
The injection is an outpatient procedure performed under fluoroscopic guidance, meaning real-time X-ray imaging is used to direct the needle precisely into the target joint. This level of accuracy is what makes the procedure both safe and effective.
Here is a simple breakdown of what to expect:
- You lie face down on a procedure table
- The injection area on your back is cleaned and numbed with a local anesthetic
- Using fluoroscopy, the physician guides a fine needle to the exact facet joint
- A mixture of corticosteroid and anesthetic is injected directly into the joint
- The needle is removed and a small dressing is placed over the site
- The entire procedure takes approximately 15 to 30 minutes
You will likely feel relief within a few hours from the anesthetic. The corticosteroid takes three to seven days to reach its full anti-inflammatory effect. Most patients return to normal activities the following day.
Some temporary soreness at the injection site is normal for one to three days. Temporary facial flushing or a brief rise in blood sugar can occur from the steroid component, particularly relevant for diabetic patients.
What Is the Facet Joint Injections Success Rate?
This is the question most patients want answered before committing to any procedure, and the honest answer is that results vary.
Here is what the evidence shows:
- For well-selected patients with confirmed facet joint involvement, HSS reports success rates of up to 80 percent
- A study published in AJR Online found that 74 percent of patients experienced a positive immediate effect from facet joint blocks
- Research reviewed at spinenpain reports approximately 75 percent of patients achieve temporary but meaningful pain relief
- A 2025 systematic review published in ScienceDirect reported clinically significant pain reduction (at least 50 percent improvement) in 13 to 74 percent of patients at one month or beyond, with higher rates in studies that used careful diagnostic selection
The range is wide because patient selection is the single biggest factor in outcomes. When a physician confirms the facet joint as the source of pain through diagnostic testing before proceeding, results are considerably better than when injections are given based on symptoms alone.
Facet joint injections also serve a diagnostic role. A strong positive response to the injection is itself meaningful information, confirming the facet joint as the pain source and opening the door to longer-lasting treatments like radiofrequency ablation if needed.

Conclusion
A facet joint injection is not the right answer for every back pain patient, but for the right candidate it is one of the most effective non-surgical options available. If your lower back pain is axial, persistent, worsened by extension, and has not responded to conservative care, your facet joints may well be the source.
Facet joint injections for lower back pain have a documented success rate of up to 75 to 80 percent in properly selected patients, making proper diagnosis before treatment the most critical step. The facet joint injections success rate improves significantly when the procedure is used as part of a broader, thoughtful pain management plan rather than in isolation.
If you are asking whether this is right for you, the clearest next step is a proper evaluation by a qualified specialist who can assess your symptoms, review your imaging, and give you a direct answer.

FAQ’s
How do I know if my back pain is coming from the facet joints?
Facet joint pain typically presents as a dull ache in the lower back that spreads to the buttocks or upper thighs but does not go below the knee. It is usually worse when leaning backward, twisting, or standing for long periods, and tends to ease when sitting or bending forward slightly. Stiffness in the morning or after inactivity is also common. A doctor can confirm the diagnosis through a physical exam, imaging, and a diagnostic injection.
How long does a facet joint injection take to work?
The local anesthetic in the injection provides relief within a few hours, though this is temporary. The corticosteroid component takes three to seven days to become fully effective. Once it works, pain relief can last anywhere from several weeks to several months depending on the individual and the degree of joint degeneration.
Are facet joint injections for lower back pain covered by insurance?
In many cases, yes. Facet joint injections are considered a standard pain management procedure and are covered by most major insurance providers, though prior authorisation is often required. The team at Cmed Regen accepts most major insurance plans and can help clarify coverage before your appointment.
What happens if a facet joint injection does not work?
If the injection provides no relief, it suggests the facet joint may not be the primary source of your pain, which is itself useful diagnostic information. Further evaluation may explore disc-related causes, nerve compression, or other spinal conditions. If the injection provides short-term but not long-lasting relief, more durable options such as radiofrequency ablation of the medial branch nerves may be considered.
How many facet joint injections can you have per year?
Most providers recommend a maximum of two to three injections per year at the same spinal level. Repeating injections too frequently can reduce their effectiveness over time and increases cumulative steroid exposure. Your specialist will determine the appropriate frequency based on your response to initial treatments and your overall health status.
