Bloated/tight stomach, please help!

[maestrooo]

a year ago a doctor suspected me of peptic ulcer and he gave me pantoprazole 40mg and domperidone for 2 weeks. Then all symptoms were gone after the treatment.  After a few months i started taking this probiotic (with 250 billion cfu) then i started to get bloated, felt like the ulcer symptoms came back. I've been like that for 6 months now. I feel like there's too much gas inside me. I don't have excessive burping/flatulence though. I don't feel any pain aside from occasional burning sensation when i'm hungry. stomach is relatively flat in the morning and gradually bloats. Could this be an ulcer, gallstones etc?

Have you ever discussed irritable bowel syndrome with your doctor?  It sounds more like that to me.
