Hi, I have been waking up with severe tightness in my chest, sore throat, and choking sensation for the past 2 years. The GERD medication was no help at all. Avoiding acidic foods and sleeping with pillow propped up did not help either. I feel very exhausted every morning. The tightness goes away after an hour every morning. I am actually pretty skinny and exercise at least 3 times a week. I think my GI doctor just about to give up on me. I can't wake up like this every morning. I know it is not cardio or I would have been dead. What is wrong with me?
