Hi
You look very distressed judging from your question.
it is a very common issue.
you may be suffering from gastric acid reflux, or a gastric ulcer.
You may benefit from a course of antacid medications.
Avoid inflammatory foods such as spicy/oily/tea/coffee etc.
have plain food for at least a month.
i highly doubt you will have relief from just avoiding food, so get a consultation and take prescribed medications for that time period.
apart from this you may need an endoscopy if your condition remains the same.
Health Tips
avoid lying down for extended periods and incorporate healthy routine in your lifestyle.
