Hi amorking2. I have been having stomach issues for the past month. Acid reflux, burning etc. I have an appointment with primary next week and I am sure I will be referred to a GI, and will most likely have to get an endoscopy. I am deathly afraid of anything going down my thoat such as you are but I have talked to many people at work who have had it done, and they say you are sedated and you are not aware. I have had chest pains, palps, and at times feelings of hard to breathe. It's best to get it checked with a GI because straydog is right, Gerd and even ulcers can affect so many areas in the body especially the chest, throats area. Best of luck to you.
