Back and neck pain can have many causes, and identifying the actual source of pain is an important part of choosing the right treatment. One possible source is the facet joints, small joints located between the bones of the spine that help provide stability and allow the spine to move.
When these joints become inflamed or affected by age-related changes, arthritis, injury, or repeated stress, they can cause persistent back or neck pain. In selected patients, facet joint injections may be recommended to help reduce pain and inflammation and, in some cases, help determine whether a facet joint is contributing to the symptoms.
But when are facet joint injections recommended, and what can patients expect from the procedure?
What Are Facet Joints?
Facet joints are paired joints located at the back of the spine. They connect adjacent vertebrae and help control spinal movement while preventing excessive twisting and bending.
Like other joints in the body, facet joints contain cartilage and are surrounded by a joint capsule. Over time, they may develop wear and tear.
Facet joint pain may occur because of:
- Age-related arthritis or degeneration
- Previous spinal injury
- Repetitive stress on the spine
- Poor posture or abnormal spinal mechanics
- Inflammation within the joint
- Changes associated with degenerative spine conditions
Facet-related pain can occur in both the neck (cervical spine) and lower back (lumbar spine).
What Are Facet Joint Injections?
A facet joint injection is a minimally invasive procedure in which medication is delivered directly into or around a painful facet joint.
Depending on the clinical situation, the injection may contain a local anesthetic and a corticosteroid. The anesthetic can provide temporary pain relief, while the steroid may help reduce inflammation.
The procedure is generally performed using imaging guidance, such as fluoroscopy, to help the doctor accurately position the needle.
When Are Facet Joint Injections Recommended?
Facet joint injections may be considered when a patient’s symptoms and clinical evaluation suggest that the facet joints are contributing to their pain.
They may be recommended when:
1. Pain Persists Despite Conservative Treatment
Many patients with back or neck pain initially benefit from conservative approaches such as physiotherapy, exercise, activity modification, and appropriate medications.
If pain continues despite these measures, an interventional treatment such as a facet joint injection may be considered in appropriately selected patients.
2. Facet Joint Pain Is Suspected
Facet-related pain can sometimes be difficult to distinguish from other causes of spinal pain.
A doctor may suspect facet joint involvement based on the patient’s:
- Pain pattern
- Physical examination
- Movement-related symptoms
- Medical history
- Previous response to treatment
Imaging may help identify degenerative changes, although imaging findings alone do not always prove that a facet joint is the source of pain.
3. Pain Is Affecting Daily Activities
Persistent spinal pain can interfere with walking, sitting, working, exercising, or sleeping.
If facet-related pain is significantly affecting quality of life, an injection may be considered as part of a broader pain-management plan.
4. A Diagnostic Procedure Is Needed
In some cases, an injection or targeted nerve block may be used to help determine whether a particular facet joint or its associated nerves are contributing to the patient’s pain.
This diagnostic information can help the pain specialist decide what treatment may be appropriate next.
What Symptoms May Suggest Facet Joint Pain?
Facet joint pain can vary from person to person. Some commonly reported symptoms include:
- Localized pain in the lower back or neck
- Pain that worsens with certain movements
- Pain with extension or twisting of the spine
- Stiffness, particularly after periods of inactivity
- Pain that may spread into nearby areas
Facet joint pain typically does not follow the same pattern as classic nerve-root pain caused by conditions such as a herniated disc.
However, symptoms can overlap, which is why professional evaluation is important.
How Is a Facet Joint Injection Performed?
Facet joint injections are generally performed as an outpatient procedure.
Step 1: Positioning
The patient is positioned so that the doctor can safely access the targeted facet joint.
Step 2: Cleaning and Local Anesthesia
The skin is cleaned carefully, and a local anesthetic is used to numb the treatment area.
Step 3: Imaging Guidance
The doctor uses imaging guidance to accurately direct a thin needle toward the targeted facet joint.
Step 4: Medication Injection
Once the needle is appropriately positioned, the medication is administered.
Step 5: Observation
After the procedure, the patient is observed for a short period before being discharged, depending on their individual circumstances.
What Are the Benefits of Facet Joint Injections?
For appropriately selected patients, facet joint injections may offer several potential benefits:
- Reduction in localized back or neck pain
- Decreased inflammation around the painful joint
- Improved ability to move and perform daily activities
- Potentially reduced reliance on pain medication
- Assistance in identifying the source of spinal pain
- An opportunity to participate more comfortably in physiotherapy and rehabilitation
The degree and duration of pain relief vary between patients.
How Long Does Pain Relief Last?
There is no single duration of relief that applies to everyone.
Some patients experience short-term relief, while others may experience improvement for a longer period. The response depends on factors such as the underlying condition, severity of joint degeneration, individual pain characteristics, and response to the injection.
A facet joint injection should generally be viewed as one component of a comprehensive pain-management plan, rather than a permanent cure for spinal degeneration.
What Happens After the Injection?
Patients may usually return home after the procedure if there are no complications.
Temporary soreness at the injection site can occur. Depending on the medications used, pain relief may occur quickly from the local anesthetic, while any anti-inflammatory effect from a corticosteroid may take longer.
Your doctor may recommend gradually returning to normal activities and continuing exercises or physiotherapy as part of your recovery plan.
Are Facet Joint Injections Safe?
Facet joint injections are generally considered minimally invasive, but like any medical procedure, they have potential risks.
These can include:
- Temporary soreness or discomfort
- Bruising or bleeding
- Infection
- Temporary numbness
- Medication-related side effects
- Rare complications involving nearby nerves or structures
The risks can vary depending on the location of the injection, medications used, and individual health factors.
Your pain specialist should discuss the potential benefits and risks before the procedure.
Are Facet Joint Injections Suitable for Everyone?
No. Facet joint injections are not appropriate for every patient with back or neck pain.
Other conditions can produce similar symptoms, including:
- Herniated or bulging discs
- Nerve compression
- Spinal stenosis
- Sacroiliac joint pain
- Muscle-related pain
- Vertebral fractures
- Other spinal conditions
A thorough assessment is therefore important before deciding whether a facet joint injection is appropriate.
Facet Joint Injection vs. Radiofrequency Ablation
Facet joint injections and radiofrequency ablation (RFA) are related but different treatments.
A facet joint injection delivers medication into or around the joint and may provide both therapeutic and diagnostic information.
RFA, on the other hand, targets specific nerves that carry pain signals from the facet joints. It uses controlled radiofrequency energy to reduce the nerves’ ability to transmit those signals.
In selected patients who obtain significant temporary relief from diagnostic nerve blocks, RFA may be considered as a longer-lasting pain-management option.
The appropriate treatment depends on the underlying diagnosis and the patient’s response to previous interventions.
When Should You Consult a Pain Specialist?
Consider consulting a pain specialist if your back or neck pain:
- Has persisted for several weeks or longer
- Interferes with work or daily activities
- Does not improve with conservative treatment
- Keeps returning
- Limits movement or exercise
- Requires frequent pain medication
Seek urgent medical attention for back or neck pain accompanied by symptoms such as significant or progressive weakness, new bowel or bladder dysfunction, or numbness in the saddle/groin region.
Frequently Asked Questions
Are facet joint injections painful?
The treatment area is numbed with local anesthetic before the injection. You may experience some pressure or brief discomfort during the procedure, and mild soreness afterward is possible.
How quickly do facet joint injections work?
The local anesthetic may provide relatively rapid temporary relief. If a corticosteroid is used, its anti-inflammatory effect may take longer to develop.
Can facet joint injections cure arthritis?
No. The injection does not reverse arthritis or permanently repair a degenerative facet joint. It is primarily intended to manage pain and inflammation.
How many facet joint injections can I have?
The appropriate number and frequency depend on your diagnosis, response to previous treatment, medications used, and overall health. Your doctor will determine whether another injection is appropriate.
Can physiotherapy be done after a facet joint injection?
In many cases, physiotherapy and exercise form an important part of long-term pain management. Your doctor or physiotherapist can advise you when and how to resume or modify these activities.
Conclusion
Facet joint injections can be a useful treatment option for carefully selected patients with facet-related back or neck pain. They may help reduce pain and inflammation while also providing valuable information about the source of spinal pain.
However, not all back pain comes from the facet joints. An accurate diagnosis is essential before deciding whether an injection, radiofrequency ablation, physiotherapy, medication, or another treatment is appropriate.
If persistent back or neck pain is affecting your quality of life, consulting an experienced pain intervention specialist such as Dr. Ishan Bhatia can help you understand the cause of your pain and explore suitable treatment options.
