I recently posted that I had "failed" my discogram - i.e. I have an mri showing mild disc herniation/loss of height at L4-L5, but when they tried to provoke pain (the discogram) in the herniated disc and the adjacent healthy discs I felt no pain whatsoever in ANY of the discs.
I did the discogram to see if I qualified for surgery - I am seeking surgery AS A LAST RESORT - NOTHING ELSE HAS WORKED (over the past 3 years I have tried EVERYTHING). I have some of the pain from facet joints, but this does not account for all of the pain (I had a series of facet joint injections).
The surgeon said I might have been too sedated during the discogram and that's why I didn't feel anything. So he wants be to get another discogram with less sedation. I'm a bit dubious, because if they hit the sweet spot for the pain - it would have been like sticking a drill straight into the nerve of a tooth - I know I would have felt it - even if they gave me heroin!
I don't really want a discogram AGAIN because it's really kind of a big deal procedure, and I knocked my front tooth out last time - I fainted after the procedure. My tooth got jammed in again, but it was a pretty powerful experience.
Anyway - just read on this site about Nerve Blocks as a diagnostic tool. I have had epidural steroid injections and facet joint injections - but no-one ever told me to keep a diary of what I can and can't do, etc. for the few hours after the procedure. The epidural steroid injection (ESI) I had was the only thing that ever made me feel better - but only lasted a week. I'm wondering if a nerve block would help determine the source of my pain. Are nerve blocks and ESI's the same?
Thanks for any input any of you can give me.
