Rein, thanks for that explanation. I wasn't looking for this topic but just stumbled across it as I'm new here. I had a discogram 2 1/2 weeks ago and it was EXCRUCIATING! However, I felt great for the next 2 weeks. I thought I was crazy and that it was a figment of my imagination! Unfortunately, the last few days my "normal" pain coming back more and more
. Darn.
