Burps got strucked in throat. Know.

Age 24 male At first I suffered from something struck in my throat. For past few days it will come and cure by itself. And later for past 10 days its not going so doctor suggested it may be GERD. Because I having lot of gastrics problem. Also I have mild congestion in starting of oropharyngeal region. After that doctor gave me NEXPRO RD-40MG and sucrafil suspension. Now it feels like I have countionusly burps after eating food but burps got strucked in throat always my throat feels soo hard and having diarrhea for 4 days so doctor again gave me rifagut-400 still I having diarrhea.(no black colour or with blood). My question is like I'm feeling only having those tablet's I'm getting continues burps before that I don't have those and also diarrhea is that GERD with laryngopharyngeal reflux or what will be the major problem. As because my age is 24 so at this age I can't bear this please help me and do exact diagnosis also I thinking that may be I have thyroid problem I don't know.
