Gas pain!?

I know this isn't the right place to post this, But since my doctor already ruled out IBS, I felt awkward posting it there.. Anyway sometimes (not all the time) I get this intense pressure/gas/bloating feeling in my stomach.. It's kind of hard to describe.. It's like gas but it doesn't really come out, it just sort of moves around a lot.. It doesn't happen a lot.. on and off for the past few months in certain situations.. I've noticed it tends to act up when my diet is REALLY sucky (Like not eating enough, not eating good enough foods, etc) It's a gurgling sensation, Like i constantly have gas in there but it won't come out.. Sometimes it does though.. It usually only lasts a week or so.. It's not painful by itself but the gas pain DOES make my preexisting back pain worse... Does anyone have any experience with something like this? My doctor has no idea what it is and told me it's probably just my diet and stress.. But since I have an anxiety disorder I'm more worried about it than I probably should be... It doesn't limit me from doing anything, it's not incapacitating.. It's just annoying :/

Any help?

Yes, I've had that happen as well. I asked my doctor about it one year and even had a abdominal ultrasound to see if anything showed up. She told me if I was passing gas than it was probably nothing to worry about. If I wasn't passing gas and I had bloating lasting more than a month or two she told me I should go to a gasto doc. This year I finally realized that I have discomfort at around the same time every year because that's when I eat a lot of crap! It's always between halloween and Xmas. After that I never have an issue for more than a day or two. I think there's a strong connection between what you eat and what's going on in your stomach. It's really hard to resist chocolate and other goodies this time of year though.

Do you still have your gall bladder?
