I am hoping someone with experience can help. My dad was diagnosed almost 5 years ago. He did chemo and radiation. As a result of the radiation damage, he will never be able to take anything by mouth. He struggles with pleghm (sp). He has a hard time coughing things up. He would take a plastic spoon, and scrape the back of his mouth to aleve the problem. He says this no longer works. Has anyone experienced this before, and did a suction machine help? Thanks to all of you for your help and guidance through this difficult time.
