Heck, Eliza, who wouldn't be feeling a bit anxious where you are at right now.
The biggest part of the anxiety is that feeling of being left hanging in the breeze. I know your rep will come thru and I'm sure s/he is busy and all, but they should realize that we need extra reassurance right after getting this implant. Did they leave you an email address to get in touch? If so, it sure wouldn't hurt to send them a quick note letting them know how you are feeling.
I really believe these guys (inadvertently) become complacent in their work, and it's good that they are reminded once in awhile that we are human and new at this.

Your body is still sifting thru several different types of pain right now, so don't cut yourself short with the meds available to you. I remember feeling a bit anxious about this at first because I couldn't tell for sure if I was getting the right kind of relief. I think I was just expecting too much too soon tho.

I know how you are tho! You're a toughie who just wants to get on the MOVE!
