I'm so sorry you're hurt and I can't even imagine the pain. I will be praying for you that you won't need surgery - I understand your fear of IVs. I hope it all works out for you. Best of luck.
EDIT:
Just saw your update!!! YAY!! I'm SO glad to hear that you aren't going to need surgery and that the damage isn't as severe as first believed. I'm praying that you heal as quickly as possible.
