Great news about the PICC line getting approved.
I had my PICC inserted in my LLMD's office with no pain killers or muscles relaxers at all. I DO NOT recommend doing it that way. I was so scared I was shaking and it hurt like you wouldn't believe.
However, my nurse is an angel and she had it in very very quickly. Once it was in, I didn't feel a thing. I've had it in 5 months and I've no troubles with it at all.
You'll do fine! We'll be there with you, ok? Let us know what day you're getting it.
Peace and health,
