Thank you for the query.
It is very hard to advice any medicine without knowing the reason of your symptoms. Most probable cause of it is acid reflux
disease, peptic ulcer
or stomach mucosa inflammation. That is why you should have upper GI endoscopy
performed with Helicobacter Pylori
test. Abdominal ultrasound
and full blood work, liver tests and pancreas tests are also advisable.
To ease the symptoms you should avoid coffee, fruit juices, fatty foods and soft drinks. Mineral water intake is advisable. Last meal should be two hours before sleeping. You can try stomach acid neutralizing medicines available without prescription.
Hope this will help.
