can anyone identify my symptoms?

I have a feeling of food touching my throat.I can feel the food down the throat.I want to burp so that I can feel relaxed.Sometimes burp would come naturally or sometimes I have to swallow some air to get the burp and with the burp  I can find some food particles in my mouth with sour  taste and at times  just food particles with  saliva.I don't understand why the food is coming into the mouth even after several hours of eating.The burp sometimes comes from the chest and is loud (embarassing).I have tightness in my throat and sometimes drying sensation of my throat.I am also dealing with minor stomach ailments.I am scared to eat food and feel week and dizzy.

I had a miscarriage 2 months back and I thought that pregnancy could cause these symptoms. But I have this pblm even after 2 months which shows there is something else going on.My pcp put me on prevacid yesterday.

I want to know if any one of you experience these symptoms and if this reflux.Pls guys..help me.

Thank you all  for your time.I have had all the blood work done and everything turned out fine.My doctor ordered some blood work for liver,kidneys etc and found everything alright.Do you think these blood tests would reveal  any pblms like gall bladder/ hernia or scanning and xrays are the only means to examine these issues.I am 24 and weigh 145 pounds with 5.5 height.

Only possiblity my pcp thought was this acid reflux which i am not totally convinced.I have an appointment with G.E after 2 weeks.I am going crazy with all the weird thoughts.

I appreciate your answers.

Thanks.
