Thank you for the query.
Your symptoms can be caused by acid reflux
disease, peptic ulcer
or even stomach cancer
. That is why, always when such symptoms appear, it is necessary to perform diagnostics before long term treatment. I suggest you to have upper GI endoscopy performed. Abdominal ultrasound and blood work should be also done. During the endoscopy, there will be Helicobacter Pylori
test performed what can be a main source of your symptoms.
In a meantime you should avoid fatty foods, spicy foods, coffee, chocolate, fruit juices. Drink more mineral water.
Hope this will help.
