blown up stomach

saturday my stomach totally blew up....I looked like i was 5 months pregnant, yesterday, it felt weird in the morning, but I didn't notice if it was blown up...as the morning went on, it totally blew up again, it didnt hurt, but just felt like it was stretched to capacity...it lasted all day long...

I woke up this morning, felt fine, stomach back to normal, then I ate a bowl of cereal, it blew up....for lunch I had 1/2 a meatball, thinking maybe the carbs were bad, but the same thing, with a little added pain

any ideas?

thurs/fri and part of sat I lived on ibuprophin and aleve because of my tooth...could I have damaged my stomach?

Re: blown up stomach

were there breadcrumbs or milk in the meatballs?

I'm thinking a gluten allergy or a lactose intolerance.

Did you have gas?

Re: blown up stomach

what kind of cereal? anything with puffyness like lucky charms for example leads to a ton of gas!
