does anyone know how to heal an ulcer around the peg tube site?. My father has a sore from the peg tube bumper, I loosened it and told him we need to keep it clean and dry. He also has been stating he has abdominal discomfort comes and goes I wonder if he has an ulcer inside where the tube is! He has been taking alot of motrin in the last month and I did get him on some prevaicid he has been taking the last 5 days. Does the chemo create this discomfort that lasts? any answers?
