Constant Gurgling In Stomach, Loud And Uncomfortable, Have Tightness, Have Gas. Tried Ginger Tea. What Can Do Done?

I have a constant gurgling in my stomach. It's quite loud and not only uncomfortable but also very embarrassing. This gurgling is typicall accompanied by a tightness in my stomach. I was told it was gas, however it's literally 24 hours a day, and I rarely have the sensation that I need to pass gas. It's sometimes quite painful and other times just uncomfortable. It doesn't matter if I'm hungry or just ate, if I ate a lot or a little, or if I ate super healthy or slightly less healthy. I've tried everything I could think of from ginger tea to gas x to culterelle to antacids. It's beginning to give me anxiety and it seems the more nervous I get about it, the worse it gets. What can I do??
