Michele, thanks for your reply. My husband is in the hospital and had some tests taken. Hopefully, we will find out what is wrong. It did seem that everytime he swallowed the secretions he felt nauseous. However, I am not sure if his secretions will ever clear up. They did a little once his radiation was finished. Chemo brought them back with a vengeance and his last treatment was in May and they are still going strong. All the doctors keep telling him to do is swallow his secretions instead of coughing them up. Thanks again, Eileeen
