Stomach discomfort independent what I eat

Hi guys, 

My stomach problems started a year ago. They are always the same symptoms. It doesn't matter what I eat I get nausea and I have a feeling like there's something heavy and large in my stomach, this goes away after a while. Whit this symptoms I get heart burns if I don't eat anything. I too get diarrhea, cramps, bloated, every possible gastric symptom actually. These are not constant, but at least once a month i feel this way for a year now. I doesn't depend on the food I eat because I tried to eliminate some food from my diet. I don't have H. Pylori, or celiacs disease, every test I had was ok. Anyone has the same problems like I do?  I would be grateful if you could help me. 

Thank you in advance 

Does your pain move about? Has IBS been mentioned?

Pain is mostly on left and right part of the abdomen, and pressure and heaviness in stomach.

Nobody said anything about IBS, but I do think it might be that plus anxiety because all of that and fear that i might get sick in public.

I would go back to your doctor and ask about IBS. Your symptoms sound like it. It is important to get a medically confirmed diagnosis.
