Gerd and Gas

This makes me so angry. about 9 months ago I went to my family physician because I was having troubles with a strange problem: I couldn't burp. On a semi-regular (twice a week - once a month) my stomach fills with gas and I am unable to expel it. It has gotten painful enough to put me in emerg. This also happens more frequently when I am physically active which sucks because I dance twice a week.
For the past month I have also been having horrible heartburn and ended up with puke in my mouth. I haven't changed any of my regular habits and my stress level is about the same. My gassy belly problem is at it's worst when my heartburn acts up. I am starting to think they are related and that I may have had GERD for the past year and not known it, and my doctor didn't think to make the connection. I am a healthy, active 17 year old and I've never really had health problems before.
Could this be true? And if so where do I go from here?
All advice is appreciated.

I agree with Cat. Also avoid complex carbohydrates, all the artificial sweeteners, soluble fiber.

Other things that can cause gas and bloating are celiac, appendix and gallblader.

You can also try adding probiotics and yogurt twice a day.
