question: i had an endoscopy this past tuesday and since then i have had extremely severe coughing occuring only at night. is this normal? what can i do about it? i have tried cough medicine, cough drops, and a breathing technique i read about, and the cough is still so bad that it is not only preventing me from sleeping but actually keeping my husband awake as well.also, one of the findings was severe ulcerative esophagitis III. does this mean i have an ulcer? thank u so very much for your assistance.
