Radio frequency ablation (RFA) is used to “kill” the sensory nerve that supplies the facet that is causing pain. If the test of that pain generation, the “facet block” give you no temporary relief, then the ablation will not work. If the block did relieve your pain, then a 3rd RFA attempt will not be effective if it is the same level. Please see these pages.
