Sure, I Would Really Appreciate. I Am A 56 Years

Sure, I would really appreciate. I am a 56 years old male. It has been a couple of days, I have got a pain/discomfort inside my abdomen. Not Sure, but somewhere around my esophagus, upper than stomach, close to my back. The pain comes, and goes, sometimes radiating to right upper back. My understanding, it is not directly to eating, but somehow is in effect. Also, heartburn is included, though not always. The other things seem normal.
