Pic Line Dilemma...

Hi everyone, I finally had my surgery on September the 27th and everything was fine with the sleeve, except for my BP and my surgeon was concerned that I would get dehydrated because I was unable to consume enough liquids to keep me hydrated. Now I have a pic line in my arm and I'm at home, was discharged yesterday, and the place where the pi line is inserted is still bleeding. I told my surgeon and he told me to take the dressing off and put a new one on there. I told him OK, but now I'm afraid to touch it, because I don't want to infect anything because when the nurse did it she had on blue scrubs and a mask and blue drapes on my arm....and I think the nurse told me to have a pic nurse to change the dressing for me, but in 1 week not the next day, I really am sick of it in my arm, but I understand why it was put there. now I am drinking my liquid diet with no problem, and urinating normally What do I do!? I'm scared to touch it

*edit* OK phew, just spoke to my surgeon and it is gone as of tomorrow, Woot!!
