Thanks for your replies, Sunbird and Denise,
I know that something is going on. I can tell by the way my body is reacting that things have changed. I also had Barrett's prior to my fundoplication. It has been under control since then.
I am not familiar with a dual channel PH monitor. I had the PH manometry twice before my surgery years ago. Are they similar? Is that what the BRAVO test is?
Where I live there are not a lot of options for GI docs. So far, I have been happy with mine, but we will see how things progress. I would have no problem getting a second opinion, even if I have to travel.
I have an appointment with my GP in a couple of weeks, it will be interesting to hear his take on all this, since my asthma has been great until this started up again.
This site is wonderful for all the information from so many different people. Thanks again for your thoughts.
