runner,
Thanks for your detailed reply. Seven month
is too long. I'm so sorry that you are going through all of this. With your description, it definitely sounds like L5/S1 is implicated in your pain.
(Of course, this is my personal opinion.)
I do hope the discogram reveals, or it least confirms, the culprit of your pain. I wish you the very best and please keep us posted after Thursday of next week.
Keep your head up--we're here for you.
