title: By the way, doctor... I've had a bothersome cough for years, and my doctor hasn't been able to make a diagnosis. Two chest x-rays have been normal. I find that coughing can produce embarrassing interruptions when I'm on the phone or in ordinary conversations. My family is worried about what might be going on. I'm not a smoker, so this isn't a smoker's cough I am talking about. Can you help me?
