I have no idea what may work for you, but let me share my story.
I always thought I was just born with a sensitive stomach. It seemed to be more intestinal than the stomach though. All my life, on and off, I'd have gas, pain, cramps, irregularity, etc..
I saw M.D.'s, naturopathic doctors, chinese herbalists, colonists, acupuncturists and massage therapists. Nothing really changed.
Then while trying to lose a few pounds, experimenting with diets, I discovered the
Blood Type Diet. I got my blood tested, hoping to be an "O". Results came back "A". Well, I found I'd been eating all kinds of food I should avoid.
So, I thought to myself, "I've tried everything else". And completely changed my eating habits, giving up many foods I loved to eat.
Guess what? For me, it worked. No pain, more energy--I rarely catch colds, flu, or ever get sick.
It's been almost a religion with me, and I rarely stray from the diet. And, for the last seven years I've known what it feels like to be "normal".

Hey, for you, this may not appeal. But, it doesn't cost a cent to change the type of foods you eat, for a week or two, to see if it makes any difference.
