I have been through two Manometries, Barium Swallows and Upper Endoscopies.
Now I am a candidate for surgical intervention for a 360 Nissen or the LINX.
If you had not had an Esophageal Manometry before, be sure to *tell* the MD or NP who will be doing it about any nasal or throat issues that you might have. In my case, the Nasal Septum was deviated, making the passage wider on one side and smaller on the other. No one asked me first (sadly) but I educated them and it felt way better by going though the wider side.
Just so you and others know.
