I had this procedure done on December 3rd. I was terrified prior to having it done after reading something that another poster wrote. She/he said they were in terrible pain afterwards.
I will say that I'm not 100%, but after my procedure was done I was a bit sore in that area. The RFTC was in L3,L4,L5,S1 and my doctor and his assistant said that I would have muscular pain after because the probe to do this procedure is larger than one that they use for an injection.
I saw my PM doc this past Thursday and the only thing I'm having that I would say is pain related is a minor twinge when I first get up after lying down and occasionally during the day if I move in a twisting way. It feels more like a pinch. He prescribed patches that I can use in that area. If this is the worse it will be, I can live with it. I see him again in 6 weeks.
Naturally, I would like to say that I am totally pain free but I doubt that any of us will ever feel like we did prior to having back problems.
The weather here has really been cold, damp and rainy so I'm thinking that may be part of my problem now. I don't know if I mentioned this but I also have arthritis in that area.
