Hi, we are new to this site & are seeking more knowledge. Bob finished 35 sessions of radiation 1 week ago for cancer at the base of his tongue. He is recovering ok, but having trouble coughing up large amounts of phlegm. Sometimes it is more like vomitting & seems to be worse at night. He is taking Boost+ and water thru a feeding tube as it is still painful to swallow. Any help/suggestions on addressing the phlegm situation. We appreciate any help. Thanks!
