Hi, I Have A Stomach Problem. My Stomach Hurts Almost

Hi,

I have a stomach problem. My stomach hurts almost every day regardless of what I eat. I was tested for lactose and gluten intolerance and that is not the problem, nor is diabetes. Usually after going to the bathroom in the morning my stomach is fine and I have no issues with farting either. But if I don't eat for a while (and not for many hours but for like 2 or 3) my stomach starts to grumble and hurt, then I start farting. Then if I eat and I do get full, my stomach starts to grumble in like 30 minutes and I feel like I'm hungry again, which just simply can't be true. I eat normal to big portions so I really never starve. I always fart in the evening, all the time in like 5 minute intervalls which is obviously very uncomfortable. And regardless of the food I had that day. My stomach just keeps on hurting. Additionally, if I feel pressure in my stomach and I experience bloating, after a while I feel like little bubbles are moving from the upper part of my stomach to my bottom and the pressure only gets better if I fart. And this goes on for hours. I hope this is something that can be treated because it's makig my life miserable.
