Thanks for the query to H. C. M. Forum.
All the symptoms which you mentioned in your query are indicators of acute gastritis
Acute gastritis may be due to overeating,
coffee or tea ( excess),
2nd reason may be mild degree food poisoning
3 rd reason may be high blood pressure
if your age is > 40 years. In that situation ,you have to consult a physician.
Antacid with pantoprazole
tablet will give you a quick relief.
Hope I have answered your question.
If further any question I will help.
