After severe vomiting, the large amount of stomach acid in the vomitus can damage the oesophageal mucosa, causing it to become congested and oedematous. If there is esophagitis or erosion of the esophageal mucosa, there may also be a burning sensation in the esophagus after vomiting. Patients who experience a burning sensation in the oesophagus after vomiting should seek prompt medical attention for a series of tests and prompt treatment.
