Over The Last Several Months I Have Had, On Occasion,

Over the last several months I have had, on occasion, the feeling that food, while eating meals, would backup in my throat when I swollowed. After a short pause it would pass on down my esophgus. Also I have developed a dry little cough which can leave my throat slightly irritated. There are no signs of swelling nor asymmetry. Other than the slightly raspy irritation it is asyptomatic. I am 70 years old and in very good health. 5' 10", 175 lb. Non smoker, occational alcohol consuption.
