Is this heartburn? No burning, but having other symptoms.

LP

The last few days, after I eat, I feel like I can’t do anything for an hour. I burp, and I feel like if I’m not careful I’ll puke, but I don’t feel sick. I just feel like my stomach and throat aren’t closed off from one another. I can’t talk much because if I do I’ll have trouble catching my breath and I sure can’t lay down or bend over. Nothing hurts or burns though, it just feels like my stomach is really high and I might puke by turning or bending wrong. I don’t know what to call what this is? I figure it’s pretty normal because I know heartburn and acid reflux are normal. I’ve never had any of this ever though, so I’m just not sure if that’s what I’m feeling? Anyone know more about it?
