For about a month, I have had a feeling of something stuck in my esophagus. I also have a pain in my chest midline. It hurts more when I eat or lay down. Sometimes when I eat or drink, it feels like it won't go down. I cannot belch unless I drink a carbonated beverage. Three weeks ago, I had a endoscopy. The doctor dialated my esophagus. In the past, this procedure has given relief for years. This time it had no affect. Can you please help?
