Strong Stomach Pains for more than 2 weeks

Hi,

I have been with some pretty strong stomach pains for more than two weeks already and I am concerned that this may be something serious. I took pepto bismol extra strength for a week and it didn't get any better.

I have had diarrhea for at least 7 days (non consecutive, more like having diarrhea 2 days in a row, then it gets better for a few days and then the diarrhea comes back).

I am not sure how to give you a good description of the stomach pains i feel, but i can say that a lot of the time i feel my stomach like "bubbling".

I have not had any "unusual" foods and after eating the pain doesn't get worst.

Thank you very much in advance for your advise.
