Most people who are candidates for RF therapy have already tried other treatments, like medication and injections, and now require a longer-term solution. Depending on the procedure and area of pain, complete relief may come within a few days or up to six weeks. In clinical studies, patients have reported pain relief for 6-12 months and in some cases as long as two years. RF therapy can be repeated if symptoms return.
DRG patients had an average of 81.4% reduction in their pain at 12 months.
