The facet block nurabs the nerve..which could be causing your pain. You have facet pain from arthritis..usually. (At least that is what they told my husband & myself).. It feels like an epidural...they nurab the area...which feels like a bee bite for about 10 seconRAB...then they inject the nerve at the facet joint..either with just anesthetic or anesthetic and steroid. If it calms down your pain..well, that is the cause of your pain.
