I am facing pain while swallowing  the right chest for the past 3 years. Its curing completely for some time. But again it's coming. I took endoscopy before 3 years and diagnosed with esophagitis grade 1 Before 3 months I undergone ph manometry test. Report was normal. There is no reflux. But now again am facing the same difficulty while swallowing for 2 months. Please guide me the causes and treatment. Its horrible experience daily am facing. I took ppi also for 1 month.but there was no use Please help me on this. Is reflux only the reason for esophagitis or some other probs?
