Thanks for choosing health care magic for posting your query.
I have gone through your question in detail and I can understand what you are going through.
Probably its a gastritis
. Due to the excess of acid in the stomach there is nausea
and headache. You should go for a bland diet and take antacids such as rantac
If this doesnt settle then you may need some antiemetic such as emset which can take care of your nausea.
Hope I am able to answer your concerns.
If you have any further query, I would be glad to help you.
