Thanks for your question on Health Care Magic.
I can understand your concern.
By your history and description, possibility of
acute gastritis due to beer ingestion is more.
But better to rule out heart diseases related
chest pain because you are post menopausal woman and heart diseases are common in this age group.
So get done ecg and 2d echo.
If both are normal then no need to worry for heart diseases.
Avoid beer ingestion.
Take
proton pump inhibitors and prokinetic drugs. Avoid hot and spicy food. Avoid junk food.
Don't worry, you will be alright.
But better to first rule out heart diseases.
Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
