Having a “gross” feeling in my stomach

[Eleoher]

I’ve had this on and off for awhile.
I’ll get this “gross” feeling in my stomach. I’m not sure how to really explain it.
At the moment I feel the need to burp but can’t. I’ll wake up in the morning having this feeling. But it’s not just in the morning I get this feeling it can happen any time of day. I could say that t happens after eating. I’ve tried peptobismol and alkaselzer.
Going to the bathroom is normal. I do feel sometimes the need to throw up but not always. It almost feels like I need to clean out my stomach.
Does anyone have any idea what this could be? I’m having a hard time explaining what I’m feeling.
