I went 3 or 4 years of having stomach pain everyday. Every time I ate it hurt, so I just skipped alot of meals. Someone at work suggested I try the natural herb Papaya. Ifgured what have i got to lose. That was about 4 months ago. Although I'm not pain free, I chew 2 or 3 Papaya after every meal and I am much better. Most drug stores and grocery stores have it and all health food stoes have it.
Well I don't know what's wrong in your case. But if you do have IBS, you can try (but this only works in 30 % of cases that I know of, fortunately for my mom it works) taking one zantac a day and see if that helps the severity and attacks. If you have something else, I really don't know what to tell you, but if that's what you have as far as I know of you just have to suffer through it, unless they have come up with something new.
