For a year I have had rumbling noises but now it has gotten to the point where I can no longer sit in my classes because I make too many noises. My lower left abdominal area is pretty loud, and also it seems like my butt makes noises too. It is worse when I am sitting. If I press against lower left ab area I can hear squealing and rumbling. This happens with anything I eat, no matter what it is. The more I eat the worse it gets. Someone please help. Thanks
