No burp causing ton of real issues??

I have never ever burped in my life, lots of gurgles, no burps at all. And I'm 21, parents recall me never burping as a child lol. Now I'm having lots of other issues like frequent heart palpitations, trapped wind, chest pain and more issues. They've come on quite suddenly. I can't help but think it could be something much worse. I'd just like someone with experience to tell me if this has happened to them or give advice. I have a doctors appointment in a few days that I'm going to use to discuss my concerns but due to my health anxiety, I feel like I'd benefit from some quick advice/stories from others. Thanks.
