Thank you Packer 66 and Brian for your quick response. Jack called his doctor's office (doctor just left to go flying-fishing for two weeks in Alaska. His doctor's nurse said that the smelly breath was normal and should go away in a couple of weeks. That's just the news Jack wanted to hear because he doesn't want to believe there's any problem. He's quite the optimist, which has come in handy especially when he's had three different types of cancer. I am still concerned that since the foul oder did not go away once the doctor took out the gauze he had sewn into the floor of his mouth to the bottom of his tongue to hold the newly placed skin graft into place that this clearly could be a sign that the skin graft is dying. Right now, I cannot convince Jack to get another opinion because he heard the answer from the nurse that he wanted to hear. Right now I'm frustrated and concerned. Is there any other signs that the tissue is dying other than a foul oder? Fever? What other problems might a dying skin graft cause? Can an infection develop and travel through one's bloodstream if left unattended? I really appreciate the responses to my questions as I am new to this forum with a newly diagnosed husband.
