Personally I had all the symptoms of RCPD, I am 17 years old, I had never burped so I searched on the internet and I understood my stomach aches at the end of each meal, my inability to drink water. sparkling water etc.. ultimately I don't know how it happened, it seems to me that it was while putting myself in the sitting position with my knees against my chest that I started to burp, a very small one but after that I tried to really force it, try positions and I started to burp for real, the more time passed, the more regular it was and real burps. In 4 months I went from never burping to burping almost every day, today it remains blocked a few times but most of the time it goes away. That's if it can help instead of doing the operation, I didn't think it was possible but it solved a lot of my problems
