I had full mobility after the RFA., it really worked well for me. I didnt use a walker or cane before this though, I just had really annoying back-pain from DDD.

I was sedated (asleep) but able to talk during the procedure cos they asked me questions apparently and I also complained about a sore leg during the RFA .,I dont remember any of it though 'cos of the drugs they gave me.

I dont know why they would only do one side, my Doc decided to do 3 levels after initially only going to do 1 level. I hope you get the same drugs I got, ask them to give you more information, I really think you dont want to be awake.
