Questions on Gastroenteritis?

I am 17 years old and have been having gastrointestinal problems since I was little. 2 years ago I had to be rushed to the ER and I was diagnosed with it. It was the worst pain I've experienced in my life.
Since then I have had small, yet painful cases of it. I try to take gas prevention pills for inflammation and cramping, and my stools are always messed up, sometimes with blood. My family also has a history with IBS, but that is not diagnosed. I look it up on wikipedia and other sites, but they just don't state plainly what I want to know.
So I'm wondering if anyone has the same problem I do, and what you have done or are doing to make life a little less painful in the stomach. This happens to me every other day. I just want some help, other than a suggestion to see a gastroenterologist.

Thanks for the link, but sadly that's the last site I looked at before I turned to Yahoo Answers.

try this link. i don't have personal experience with it but i looked this up and thought it might help.

One, gastroenteritis is an infection of the gastric system usually bacterial. Can have diarrhea, cramping (severe), vomiting, nausea etc. Treated with antibiotics and fluids.
IBS is a syndrome of symptoms...bloating after eating, gas, rotation between multiple stools a day to constipation..is constant happening, also can cause cramping. Certain foods can aggravate it. I have IBS and am on medications for relaxing the colon, the diarrhea episodes, and have found that cream cheese and certain milk products bother me.
Stress doesn't help at all either.
I know you didn't want the advice to see a gastro doc but to get on the right medicines he would prescribe them and you wouldn't have to see him all that often. You would soon learn to live with it and which medicine helps to control it as well what foods to avoid.
