I had surgery to correct a hiatal hernia and acid reflux a year ago this past Nov. and ever since, I have difficulty breathing just about every other day. Prior to surgery, it was more frequent. I sleep on a wedge pillow, plus another standard pillow to prevent acid coming up, and I eat by 5:30 to give adequate time for food to digest (this has helped tremendously to the point where I don t need medication regularly, but wonder why it happens every other day and is there anything else I can do? And is it happening because acid comes up to my airway and creates swelling? PS--my pulmonologist prescribed inhalers, but it brought no relief whatsoever.
