So sazzy, I'd say you are lucky to have found a good pulmonary specialist; I had to go to Nat'l Jewish in Denver to get a good one.
First, lets discuss your Bravo. I have had two and had no problems; you're prepped for endoscopy, normally given a mix of versed and demerol, so no pain, no memory..life is good. They will check out the esophagus for any number of things and while there will insert a capsule into the wall of your esophagus. I can't say that it made much of an impression on me because I may or may not remember feeling it...so not a big deal. The capsule has a transmitter and it will electronically send signals to a little recording box you will wear on your belt (honestly, the whole wearing it around your neck really bothered me, so I wore it around my waist).
You will record information as instructed for a period of 48 hours, after which your recorded turns off and you return it to the Dr.'s office. In the meantime this capsule is hanging around taking up space in your esophagus and will let go and move through your system without you even knowing it.
Don't fear the test!
Your pulmonary symptoms; I was treated for years for different types of pulmonary issues, and while everyone agreed that the symptoms weren't exactly this or that, they didn't know what it was...trips to the pulmonary specialists in mid-Michigan were of zero value. Eventually I was sent to National Jewish; there they determined that the reflux (which I thought was a minor matter) may actually be a major player. They sent me for tests and holy cow, was it a big deal. The reflux was making me a pulmonary cripple; I was aspirating while sleeping (who knew) and by this time my lungs were very inflamed and my alveoli, fibrotic as are the very ends of the bronchiols.
The surgery I had in July (Nissen-Cleveland Clinic) probably saved me from a life connected to oxygen tanks. My lung function is amazingly wonderful, and while the damage I have is permanent, I can breathe, hike, walk up hills and stairs and walk miles on the treadmill. An amazing feat for someone who could hardly walk two blocks one year ago!
It sounds like you are on the right track; take the steps to find out what and when and why and how and go with it.
