Thanks for writing your query.
After reading your post, it seems that you might be having symptoms due to gastritis.
I would advise that you should get yourself clinically examined and investigated.
Following investigations may be helpful :-
2. Liver Function Test ( LFT ).
I would advise that you should take an antacid like Omeprazole
40mg once a day before meals along with Domperidone
along with digestive enzyme
preparation containing pepsin and fungal diastase after meals will also be helpful in controlling your symptoms.
Eat light meals prepared under hygienic conditions.
Further medical management can be planned after knowing the reports of the investigations.
I hope this is helpful to you.
