My husband has stage 4 renal cell cancer. He is having sever diarrhea, I took him the ED last night they gave him 2 bags of fluids and zofran. We came home with a prescription for phenergan. He is still having diarrhea and doesn t have much of an appetite. I ve been giving him applesauce, gatorade, and pedialyte, I also got some probiotics for him. I really don t know what to do to help him. Any suggestions would be helpful.
