When Is Facet Joint Injection Recommended for Facet Joint Syndrome?

Facet joints are small joints at the back of the spine that help guide movement. Irritation in these joints can cause neck or back pain, stiffness, and pain that worsens with extension, twisting, or prolonged positions. Similar symptoms can come from discs, muscles, nerves, or other spinal conditions, so an injection is not selected from symptoms alone.

A clinician may recommend an injection when the pain pattern and physical examination point toward a facet joint, exercises and other non-invasive measures have been tried appropriately, or pain is limiting rehabilitation. The injection may place local anaesthetic, sometimes with an anti-inflammatory medicine, near the suspected joint. Temporary improvement can provide useful information about the pain source, but it does not replace a broader diagnosis or rehabilitation plan.

Arrange an assessment with a qualified clinician who can review the location and pattern of your pain, movement findings, medicines, allergies, and relevant medical conditions. Bring a list of treatments already tried and describe what made the pain better or worse. Ask whether physiotherapy, activity modification, heat, or other options should continue alongside the procedure.

If an injection is planned, follow the clinic's instructions about medicines and transport. Afterward, follow the advised activity limits and monitor the injection site. A short period of soreness can occur; increasing redness, drainage, fever, new weakness, or worsening pain needs prompt medical advice.

Seek urgent medical care for new loss of bladder or bowel control, numbness around the groin or inner thighs, rapidly worsening leg or arm weakness, or severe pain after a significant injury. These features can indicate a problem that needs prompt assessment rather than an elective injection.

Contact a clinician promptly for fever with back pain, unexplained weight loss, a history of cancer, or pain that is severe at rest or repeatedly wakes you. If you have already had an injection, urgent review is also appropriate for breathing difficulty, facial swelling, widespread rash, or signs of infection at the injection site.

Ask: What findings make you think a facet joint is contributing to my pain? What other causes have been considered? Is the injection intended mainly to confirm the pain source, reduce symptoms, or support physiotherapy? What medicines or conditions could affect the plan? What should I do if it does not help?
