Hello!
I have been experiencing this feeling for a quite awhile. When I first started singing lessons I realized this more. Whenever I tried to breathe in deeply and into my diaphragm, I would feel tight and could not breathe in any more air. I felt like a balloon that was going to pop, even though I only took in a tiny breath. So when I would sing, I would always run out of air.
Also when I breathe in, my stomach will make noise! It will growl. I am not even hungry but after a deep breath it will rumble. Also, I always feel a heavy sort of feeling in my lower abdomen, like a rock is just sitting in the bottom of my intestines.
I am not sure what to make of this! I have been diagnosed with GERD in the past, but that has gotten much better. I have yet to go to a Gastro doc. Anyone have any clue as to what this might be? I want to be a professional singer and this is really inhibiting me.
Thanks much!
