A facet joint injection is used both as a diagnostic tool and an effective pain-relief therapy. Physicians are capable of detecting the afflicted area(s) through fluoroscopic (x-ray) technology. A local anesthetic is applied to the corresponding body region before the procedure and a corticosteroid anti-inflammatory medication is applied to afflicted areas as they are identified. The result is relief of pain and inflammation in your joint and verification of the origin of your pain, since facet joint injections are performed using local anesthetic and allow for real-time feedback.
