Hi...based on your history you may might be suffering from GERD!! There are several causes of GERD...most common one is stress..
As u have already got endoscopy done and there is no mechanical obstruction....which is a good thing...
Esophagitis due to GERD is curable...provided u don't lose the hope and continue with the lifestyle changes and use medications as advised!!
Remember "the more u stress...more stress hormone is released...more acid is secreted...more time for recovery"
Next Steps
if possible post the endoscopy report!
Health Tips
