Thanks for your replies. I think it was indigestion. I had horrible stomach ache all day and I think it may have been something bad I ate. I have never really had any big problems with gas, heartburn or indigestion. I ended up taking a pepcid AC and I guess it worked cause it went away shortly after and I felt fine but boy was it scarey. I never thought gas traveled that far up in the body and then just got trapped like that.
