I did have one done and it was not as bad as i thought. I was kept asleep then woken up right after needles were inserted in my disc so I could tell them where the pain was coming from. As soon as I yelled i was back asleep very quickly. I had a ct run right after. I will tell you I was in alot of pain after this procedure for a week and the first 3 days were horrible! My pain has gotten worse since this procedure was done but my condition has worsen as well. I am being recommended for a 2 leve fusion fro l4 to s1. Let me know how it goes for you. good luck
