Angela, sorry no one has responded to you yet...I`ve dealt with a lot of fistulas with Frank.What does the doctor say about the cranberry lumps. It sounds to me like granulation tissue, if so, the wound is trying to heal. After one of Frank`s surgerys, he came home with whole side of his face exposed including bones because a graft wasn`t possible.....as far as treatment, all we ever did was wet to dry dressings. I know fistulas are scary as hell........Frank`s usally appear on his neck now.............If you haven`t yet, ask the doc what the cranberry stuff is exactly...............Love, and Prayers, Dee
