I've had a Sleep CPAP for over a year now. But I keep getting stomach issues from the air blowing into my stomach or so it feels that way. I have acid reflux Gerd, and have been checked for Barrett's Esophagus twice, both being a negative result for any type of cancer. But the doctors did note that I had slight hiatal hernia and that the valve to my stomach doesn't close properly. So with the above being said, and when using my CPAP I get stomach pain every time I use it, and it seems like and feels like the air from my CPAP is blowing down into my stomach, I need to know if this is causing other health problems, am I at risk of developing a health problem if air from my CPAP is being blown into my stomach? Also I'd like to add that I am seen by the Veterans Administration (V.A.) Hospital for my health care, I am a 100% disabled Veteran, and we all know that the V.A. Hospital has a tendency to not do such a great job of taking care of their Veterans. So any help from you on this subject of my health would be greatly appreciated so that I can make the V.A. Hospital treat me like their suppose to. Please and Thanks.
