Hi. I m wondering what specialty would be the best to consult with regarding a very dry and chronic cough? It has been getting worse and actually started in 2001 after a trip to China. (I was there again in 2009). My Family Practitioner has taken periodic X-rays of my lungs but they were clear. Recently I wake up at night coughing and cough throughout the day. My throat becomes dry and drinking water does not have much effect. Thanks vey much for your time and any advise you might give me.
