Benefits of receiving a lumbar facet block injection include reduced tissue swelling and inflammation in and surrounding the facet joint space, according to OhioHealth MedCentral Hospitals. The injection also lessens pain and other symptoms resulting from irritated areas around the space.
A lumbar facet joint block can be useful in diagnosing the origin of pain and as a pain-relieving treatment, notes the University of Maryland Medical Center. A physician may administer multiple injections, depending on the number of joints that are affected. Many patients experience immediate temporary relief from the local anesthetic. However, it is the injection of steroid medication that produces relief for up to a few months, explains OhioHealth MedCentral Hospitals.
