I've had an ongoing problem relating to stomach gas for a while. When I get a lot of trapped wind in my intestinal area, I have a feeling of tightness in my lower abdomen and it's difficult to get a full satisfying breath.

I have been to doctors about this, and they have ruled out heart problems and lung problems.

Of course, it is stress and anxiety that usually causes these bouts of stomach gas in the first place...

I have two questions regarding anxiety and excessive gas..

1. Can gas cause shortness of breath?
and
2. Can anxiety cause a bout of gas and digestive irritation that lasts for several days after the initial anxiety trigger of the event? That is to say, is it normal for somebody to go through a very stressful Wednesday and still be feeling digestive symptoms of it on Friday?
