What are the potential causes of persistent dysphagia, chronic morning cough with yellow sputum, nighttime sore throat, and sleep disruption in a patient whose deep esophageal ulcer has healed but who remains symptomatic despite twice-daily pantoprazole therapy, and which medical specialist should be consulted for further evaluation?
Since twice-daily pantoprazole isn't fully helping, these issues might stem from non-acid reflux, an esophageal muscle movement disorder, or even a localized throat or sinus issue causing the morning cough and sputum. I highly recommend consulting a gastroenterologist to perform specialized tests, such as a pH study or motility test, to see exactly what is happening. An ear, nose, and throat (ENT) specialist would also be very helpful.
