I had RF ablation of my L3-L4-L5 facet joints back in April of this year and it gave me 100% relief for about 5 months. I just had it redone a week ago. My doctor does one side, waits 3 weeks, then does the other. I felt like a new person when the pain went away.
Prior to the RF ablation procedure, he injected steroids into several places to pinpoint the source of my pain. I got about a week of relief from the steroids once he zeroed in on the source.
Best of luck. If you had it done as scheduled, you should be filling some relief now.
