Karin, sorry about the latest nail-biter chapters (and also the part that the emoticon so wonderfully expresses!). Regarding the pre-certification, are they certifying the procedure and your appropriate condition for certain procedures? It sounds tricky.
And from what I've heard and read, arthritic or compromised facet joints could be a huge risk factor for ADR. So that sound logical to me.
Good luck tomorrow! Don't punch too many people!
And let us know what you hear from the doctor's office.
