I just had two kidney turmors removed on Friday, April 7th. It was diagnosed as renal cell cancer, my spleen was knicked and sewed up, I had a blood transfusion because I lost a couple liters of blood. I came home on the 10th. I am having problems after eating, my stomach bloats up and hurts (back, abdomen, kidneys) . I get weak and neausous, I am very constipated, I have very little bowel movements, I have used stool softners, laxatives, enemas. I have vomitted twice both times it looks like black liquid. What should I do?
