Im a 30 year old male, and for the past few months I have been experiencing some type of gas movement in my stomach. This has been happening everyday, both at home and at work. I work a swing shift so I wake up around 1pm, dont eat anything, start work at 3pm, then have my lunch break around 7pm. Typically around 5pm I will get aches in my stomach, feels like my stomach is moving around, and every now and then belching occures. This goes on until I eat my lunch around 7pm. A couple hours later around 10 or 11pm the issues will return until I eat again after I get off work.

Its a strange feeling, like your stomach being empty so it trys eating itself, only about twice as bad. Once the feeling starts, it will come and go, the issue last about a minute then is gone for about 5 or 10 minutes, this goes on until I eat something. Anybody have any idea on what this may be? Im not taking any medication, and havent had any problems before.
