Generally Good: Radiofrequency procedures work well if a previous facet injection or medial branch block was performed with greater than 75-80% relief that was obtained. As with anything there are failures, but quite low if the block worked well. Risks are the same as with any spine procedure, no different. Rare that you would be worse off afterwards. Generally relief can last 1-2 years.
