Sick/weird feeling when stomach is empty????

For the past 8 months I have been experiencing a weird sensation when my stomach is empty or I haven't eaten in a good period of time.

I don't know how to explain the feeling. It is not hunger and is not really pain.
It is rather uncomfortable tho.

I guess the best way to explain it is a slight pressure sensation right where my stomach meets the esophagus. It can kind of feel very slightly nauseating as well.

The second I eat anything it will instantly go away...

Does anyone have any clue what this could be and what causes this?

It sounds like you might have high stomach acid. If you feel really weak it could be an issue with blood sugar also. A lot of the herbs/antibiotics can increase your stomach acid. Not sure what the best solution might be. Are you dairy free?
