Michelle,
I've read about a few other women that have delivered and had ADR (not sure if Prodisc or Charite) tho as I recall there were no untoward events re delivery and disc prob. And I believe upon questioning Dr.Bertagnoli he thought they'd be Ok (so must have been prodisc patients)..
I'd have to go back and see when you had your first baby and if that was recent and/or vaginal delivery tho if in the last several years, your delivery unless otherwise problematic would likely be easier on you, than more difficult.
I have a friend whose daughter had 2 children after her 2 level lumbar fusion at L4 and L5S1 and believe it or not (I found it difficult to believe) she's fine. No further back probs. Vaginal deliveries both.
Glad to hear the pain med weaning/cessation went well and hope soon you'll be able to sleep. Sounds like you're doing good so far! Keep us posted
