If a patient is experiencing lower back, buttock and/or upper leg pain, then it could be indicative of an issue with the lumbar facet joint. The patient might enjoy temporary relief by the injection of a local anesthetic into the lumbar facet joint. The pain relief that patients experience following this procedure can last for several hours. If the procedure is a success, it will allow doctors to predict how effective a future treatment might be, to disrupt the function of the nerve supply to the lumbar facet joint. If this second procedure is viable, then it could offer long-term relief from the pain.
