I have this unproductive cough which worries my husband. He said something to the Dr. who replyed something about side effects of chemo and also said if it was anything to be concerned about, it would show up on my ct scan which I have every two months. I got to thinking and I had this type of cough the last time I was on navelbine. It seems to be worse when I am eating. I was wondering does any one else have a cough with chemo? Patty H
