I Have A Dr Appointment For Tuesday Afternoon With My

I have a dr appointment for Tuesday afternoon with my family doctor... For the past two months I've been having chronic indigestion (6-9 times a day) and lots of gas. I have cut out dairy,tomatoes, fatty foods from my diet but an still having a horrible time with my GI tract. My stools are normal and regular for me. I am a nursing student and everytime in my assessment lab when I have to be the patient my peers note my hyperactive bowel and bubbling up in my upper abdomen. I have a constant sour taste in my throat and cannot lay down without feeling burning in my chest up through my esophagus. The gas in my intestines has been so painful that I couldnt breath normally without feeling like I was being stabbed. I had to take shallow breaths. can Acid reflux cause problems in my intestines? Im assuming I don't have gastroenteritis because I don't have diarrhea. I know there are lots of things my symptoms could be but does any one thing stand out? I am a nursing student so I know a little more than the average person and I know a diagnosis cannot be given through the Internet but I'm curious as to what this could be.
