Facet joints are one of the most common causes of spinal pain, both in the neck and the back. The facet joints are the small joints in the spine that allow you to bend and twist. A facet joint block is a minimally invasive procedure where the physician will inject a local anesthetic and anti-inflammatory medication to numb the facet joint and provide pain relief. Fluoroscopy is used to guide the needle for accurate placement into the facet joint.
