Hello KEI!
Just wanted to pop in and say that I have had a discogram done, and I received sedation for the procedure, and it was not that bad at all, However they will not put you clear out as they need feed back from the patient. If your Tech performing the Discogram does not use sedation, then it could be painful like an epidural, if you have ever had one done. The procedure is used to detect which disk is causing your pain, and needs further treatment such as a fusion, like in my case. I had a double lumbar fusion at the L4-L5, L5-S1
location.
Good luck,
SE
