How Can Swelling In The Right Arm Be Treated?

I had a kidney transplant Dec. 11 and it did not kick in, it was on ice for 18 hrs. I think they are infiltrating it when they keep sticking me in the same place, as I get black and blue also it is swelled at least 3 times the side of my right arm, my hand is swollen too and I keep sleeping with warm heating pad on it at night propped up on a pillow. Have had two ultra sounds of the arm, and in the neck and under my arm, they say there is fluid in there but not sure what kind, have had a graft-o-gram in Oct now they are saying I need another one and am trying to get one as soon as possible. I do have black and blue marks on my arm and have asked them to stick me some place different , now it doesn t bleed as much at the end? Help?
