Understanding Facet Related Pain
Facet joint injections may be considered for some people with ongoing neck or back pain, but they are not a treatment for every cause of spine pain. The small joints between vertebrae can contribute to pain, yet symptoms alone cannot confirm that they are responsible.
An injection may help test whether a facet joint is contributing to pain, provide relief, or serve both purposes. A clinician considers the pattern of symptoms alongside imaging, since scan findings by themselves do not establish the pain source.
At Orthopedic Spine Institute of St. Louis, care starts with conservative options, with minimally invasive procedures considered when appropriate. Whether an injection fits, and what benefit to expect, depends on an individual clinical assessment.
What Injections Treat and How They Work
Facet joints are small joints connecting neighboring vertebrae from the neck through the lower back. Arthritis, injury, and disc degeneration can affect these joints and contribute to pain. A facet joint injection places medication in or around a joint, sometimes near the medial branch nerves that carry pain signals from it. For more background on how these injections differ from epidurals, see facet and epidural injections.
The name describes where the medication goes, not what it contains. Local anesthetic is commonly used to numb the area. On its own, it can help assess whether a facet joint is contributing to pain. A corticosteroid may be added when the aim is to reduce inflammation and symptoms, but it is not part of every injection. The choice depends on the purpose of the procedure and the clinician’s assessment.
Pain centered in the neck or back, sometimes worsened by bending, twisting, or arching, may fit a facet-related pattern. Neck discomfort can also spread toward the shoulders or upper back. Symptoms alone do not confirm the source, and imaging findings need to be considered alongside them. Pain that mainly radiates down an arm or leg may have another cause. At Orthopedic Spine Institute of St. Louis, care starts conservatively, with treatment choices based on an individual evaluation.
Relief varies. Temporary improvement while the anesthetic is active may offer diagnostic information; treatment-related relief may last longer, but is not assured. One small study of people with persistent pain after lumbar surgery found modestly lower pain scores and improved spinal mobility at six months, but no significant improvement in disability scores (study). Those findings do not establish the same benefit for everyone. A clinician can discuss whether an injection fits your symptoms and what outcome is realistic.
What to Expect During the Procedure
The exact process can vary by clinic and by the joints being treated. In general, the care team cleans the skin using sterile technique, then injects local anesthetic to numb the area. The clinician guides a thin needle toward or into the target joint, usually with fluoroscopy, a type of real-time X-ray. CT or ultrasound guidance may also be used. This image-guided approach helps the clinician place medication in the intended location.
Most patients do not receive sedation. The numbing medicine may sting or burn briefly, and you may feel pressure as the needle is positioned and medication is injected. Experiences differ, so tell your care team if you feel sharp or increasing pain. The procedure itself may take around 15 to 30 minutes in some settings, but timing and any observation afterward vary.
Before the appointment, share your medications, allergies, and health conditions with the clinician, and follow the instructions provided for your situation. Do not stop a blood thinner or change any medication unless your care team directs you to. If sedation is planned, follow the facility’s preparation instructions and arrange for someone to drive you home.
Afterward, mild soreness at the injection site may last a day or two. Activity and medication guidance can differ, so follow the instructions from your own care team. At Orthopedic Spine Institute of St. Louis, evaluation and treatment planning are tailored to the patient’s symptoms and circumstances, rather than relying on imaging alone.
Recovery, Risks, and Warning Signs
Some soreness or a short-term increase in pain after a facet joint injection is common. Pain may also return when the numbing medicine wears off; if the injection included a steroid, its effect may take several days to appear, and it may not help everyone. Recovery varies, so follow the instructions from your own care team. MyHealth Alberta’s aftercare guidance notes that activity and symptoms can differ from person to person.
Possible short-term effects include tenderness, bruising, minor bleeding, temporary numbness, or swelling near the injection site. If corticosteroid was used, facial flushing, insomnia, or jitteriness can occur temporarily; blood sugar may also rise for a time, which is worth discussing with your clinician if you have diabetes. The Hospital for Special Surgery’s facet injection guidance describes these effects and notes that serious complications are uncommon.
Infection, bleeding, allergic reaction, and, very rarely, nerve injury are possible. Before treatment, tell your clinician about blood thinners, bleeding disorders, allergies, diabetes, and other relevant health conditions. At osistl.com, care for back and neck pain starts with an evaluation and conservative options, with minimally invasive procedures considered when appropriate.
Take it easy after the procedure and follow your clinician’s individualized activity instructions. HSS recommends avoiding heavy lifting, intense cardio, and weight training for at least 48 hours, but instructions may differ by patient and clinic. A cloth-wrapped cold pack used for 10 to 20 minutes at a time may ease tenderness; check with your care team before taking pain medicine.
Contact your care team promptly for worsening pain, new numbness, tingling or weakness, increasing redness, warmth or swelling, or fever. Seek immediate medical care for loss of bladder or bowel control. Call emergency services for trouble breathing or inability to move an arm or leg. If symptoms are not improving as expected, osistl.com’s patient-first approach supports discussing the next step with a clinician rather than assuming the injection has failed.
Planning Care Beyond the Injection
An injection is one part of care, not a complete plan for every source of neck or back pain. Depending on the evaluation, physical therapy, rehabilitation, and changes to daily activities may help support the muscles around the spine and maintain movement. The Hospital for Special Surgery overview of facet joint injections describes exercise and rehabilitation as possible parts of ongoing care.
If a diagnostic block points to a facet joint but relief is brief, a clinician may discuss radiofrequency ablation, which targets nerves supplying the joint. HSS reports that relief may last roughly six months to a year, though results differ among individuals. At osistl.com, care begins conservatively, with minimally invasive procedures considered when appropriate.
Injection timing depends on whether the goal is diagnosis or treatment, how a patient responds, and individual circumstances. HSS describes one or two diagnostic injections as typical and cautions against frequent repeats when relief does not last. If an injection does not help, follow up with your spine specialist to review the suspected pain source and consider options such as rehabilitation or further evaluation.
Facet-joint problems alone are typically not treated with surgery, but other spinal conditions may need separate assessment. Persistent or worsening symptoms warrant an individualized evaluation. Insurance coverage and prior authorization requirements vary, so confirm them with your insurer and care team.
A Personalized Path Forward
An injection may be one part of care, not a guaranteed fix or a substitute for identifying the source of pain.
If symptoms persist, discuss your symptoms, imaging, goals, and risks with a qualified spine clinician.
