Hello, I play the tuba for my high school band. Since last year (not all the time, but mostly when I am tying to take deeper breaths it starts) I have been burping a lot. It feels like every breath I take is adding to air that I am burping that comes out every few breaths. In addition, at the end of a very deep breath in it feels like the air that has added up to a burp is pushed out. I mentioned this at a physical I did and they did not know what it was. It is impacting my playing a bit, and is getting a little bit annoying that it keeps coming back.
