Indigestion &fud comig bk. Shld i do?

Since 1year, I hvsymptoms of fud coming back to my mouth after eating. Nw most of the foods are coming back. I did not take any medication so far. Bt 2weeks back, I had sever throat pain & ear pain. No fever or cold.ENT diagnosed pharyngitis due to acidity in stomach. He gave 5 azithral-500, wikoryl fr 1week, gaviscon liquid & rabilife tablet. In-between, I got severe stomach pain from eating meat. I went to Gastrology DR. She gave me VSL#3, razo-L & razo-20. I have stopped the previous medicines & now i m taking these medicines with wikoryl. Azithral-500 doze is completed. Now my stomach & throat pain has subsided.But what is worrying me ,all these days I had the same problem (food coming back after eating). Even after several hours, certain foods come back & I had to split it out. I thought it was bz f acidity, but even aftr so much medications no change for that. Pls tell me what is the reason fr ts?what shld I do ? I m totally irritated &worried. (Did scanning 2mnts bk,no issue)
