Thanks for writing your query.
After reading your post, it seems that you are having symptoms due to anxiety
or due to increased gas production in the stomach.
Still you should get yourself clinically examined and investigated.
You should get following investigations like :-
3. Chhest X-Ray PA view.
You should get your bloood pressure and pulse rate monitored.
You can take antacid like Omeprazole
20 mg once a day before meals along with Domperidone
10 mg for relief.
Rest medicines can be planned according to your clinical examination and reports of the investigations.
Doing yoga and meditation
will also be beneficial.
I hope this is helpful to you.
