Shelagh- one of John's tumors opened up the outside of his jaw also.[ you could see from outside to inside his mouth] However, since everything he ate or drank was by peg, we didn't have the same issues youall are having. I hope your sister is well medicated and that everyone who is important to her is getting to spend time with her. From this point on, your family will have to be very strong and "together". My main goal during John's last weeks was to keep him pain free and be with him. Amy in the Ozarks
