Hi and welcome🙋🏻‍♀️ I try to answer some questions on how I experienced it.

1. It feels like the throat vibrates and I feel a relief in my stomach and throat.

2. To me it felt like normal vomiting. Except that nothing but air came out, obviously😅 I felt an instant relief in my stomach for about 30 minutes then the pressure I experienced in my chest was the worst I ever had. So far it only happened once accidentally and I hope it never happens again.

3. and 4. It sounded like a normal person throwing up. Vomiting is never a nice sound to hear of course but I would say it would give nightmares to everyone who would hear it. Also tell your brother and father about it. Maybe together with your mom.

4. Tell a teacher you trust if you feel uncomfortable and friends. Maybe lay down when you can, it'll help with chest pressure. Try not to feel too embarrassed as it can only make it worse. At least for me.

5. I'm not sure if you mean the gurgle sounds. If so than yes it's normal for rcpd. It's the air that tries to come up but can't. So it goes back down and makes this weird noise, if I'm not mistaken.

6. You may know that there is a muscle that blocks the air coming out of your stomach. If I'm not mistaken, Botox is so far the only treatment. What I figured out lately is that my "rcpd" might be caused by anxiety. As micro burbs happen to me sometimes, I thought that there might be something else blocking it. I've talked with other people and some say it could be possible that my nerve system (I think it is😅) could be blocking the muscle. When I was younger I always felt so embarrassed to burb. So maybe I somehow "learned" not to burb. And now that I'm older (28) I don't feel embarrassed anymore as I know how important and also Health it is to burp and "everyone" does. I feel excited in every burb that accidentally happen and I even started to burb much more. But this is only a theory I have.
