juice authority, YOU can't sit here and give other people advice and medical help - when all you're concerned about is health insurance.....
oh noes, insurance companies may freak out....so? i'd rather have my leg than a mark on my insurance record.

IF you have to go. tell them you injected b12. nothing more.
