Definately go and see a GI dr. Honestly, they are the only ones who can truly diagnose these problems to make sure you don't have something else going on.
I still havent found anything that will put my stomach right again. Like I said, the PPI's have really destroyed it!! You might want to try digestive enzymes. They help me a lot. Get the ones from you health food store if you can. Twin Labs makes a good one and they arent too expensive.
However, I wouldn't try anything new until you get in to see a GI dr cuz you don't want to aggravate anything.
