Yes, the same thing happens to me. But it's very intermittantly, and I'm never sure why it hits. I think it's usually after I've mistreated my GI tract for a few months. In another post, I tell of the time when I had to sleep upright in a chair for 7 months, because of this sensation. My upper chest and neck felt sooooo full, that I felt like I couldn't breath. the only thing I can think of, is that maybe I had so much bloating, that it pressed on my vessels, so that maybe things got congested in my upper body.
There were even times when I felt like my stomach and diaphragm were actually constracting. I could feel it tighten up.
So......you're not alone. Sometimes I wonder if there is a malfunction of our nervous systems that affect our GI tracts. During these times, I take alot of Gas X, which helps a little bit. But what helps the most is to really reduce the amount of food I'm eating. Sometimes, I even have to almost fast for a few days to get it under control......then start back eating very small amounts. And I think carbs do make it worse. I do think it is one of the possible symptoms of GERD. Good luck to you!
