A facet joint block or injection is a minimally invasive procedure in which a physician injects a small amount of local anesthetic and/or medication to numb a facet joint and provide pain relief. Fluoroscopy, a form of real-time x-ray, or CT is used to guide the placement of the needle into the facet joint. This treatment does not offer permanent pain relief. Patients may have one or two repeat injections over a six-month period. It is not recommended that a patient receive more than three injections in this time frame. During the injection of local anesthesia, you may feel a pinch and some slight burning as it takes effect. However, it should not cause intense pain. The facet joint injection itself should not cause any pain since the area will be numbed. You'll likely feel some pressure around the injection site.
