Has anyone here ever had a Medial Branch Block? It's apparently a diagnostic tool that rules out facet joint pain. They temporarily numb the nerves of the back and if you get somewhere from 2-6 hours of relief (no pain) then it's successful and they will do a more long term form of that procedure. This supposed long term procedure involves literally "burning" the nerves. I've interpreted this to mean that they merely block the receptors that perceive pain. I've been recommended this by the PM. Per my MRI results, I have a herniated L4/L5 disk. I have had terrible back pain and more ongoing bouts of sciatica primarily on my left leg but since the one ESI that I had, my right calf area is becoming affected. I'm too young for this, I'm only 20 but I'm going through the processes that some of you I believe have gone through. So, the way I see it, how beneficial can numbing nerves be? I mean, if it's successful and I don't feel pain, well....it appears as though I'm not going to feel much of anything else either. How can that be a good thing? What does anybody think out here about this??? I have no choice but to go through with this but I was wondering if anyone else out here has had a medial branch block. Any input is greatly appreciated. -Anita
