Possible Dysphasia

I saw the gastroenterologist today and he set me up for a barium test with a pill to swallow and thinks it may be Dysphasia.  I will have the test next Tuesday morning and the results the following day and after reviewing  the x-rays will determine if an endoscopic test is necessary. My question does anyone have this Dysphasia, trouble swallowing certain foods and clearing their throat. I will keep everyone informed after the test.  Phil A.
