my father recently had a graft put in his arm for dialysis. His arm got extremely swollen and long story short they took it down. It is still in the arm but tied. His arm has stiil been hurting and oozing yellow fluid out of his skin. A surgeon just came in and thinks it is infected and waiting on Vascular to look at it. my question is what type of infection might it be. Waiting on culture results. He recently had a stem cell transplant so I am extremely worried.
