I get burning pain in the center of my chest too. And a bit of shortness of breath and lots of hiccuping. I've had about three EKGs done and Oxygen testing (on my blood). All fine.
I was DX with Gastritis years ago and take Nexium whenever it flares up. I had the pain / pressure, etc. again last night. Gastritis (mostly caused by H.Pylori bacteria) goes hand-in-hand with Candida, so I've learned. (Or, at least, one doesn't help the other.)
Basically, take stock of what you've been eating. If you've been OD'ing on Red Meat, Caffeine (even sometimes DECAF tea can cause pain), tomatoes, etc., you may want to try cutting some out and see if it helps a bit.
Also, try taking DGL extracts. I've been using these (see link I attached below, but you can find them at virtually any health food store) with great success for the last couple years (had BAD reactions to my usual RX of Zantac and Prilosec, so Doc RX Nexium...but since it's NOT covered by United Healthcare and costs $150 a bottle, I use it VERY sparingly.)
They cost under $20, don't taste that great, but if you're in pain, a bottle of these can be cheaper than the Doc's office. Oh, it says they're chewable, but I always SUCK on them until they get tiny, and only THEN do I chew and swallow. I find sucking on them like a cough drop (again, they don't taste that great, but you get used to it) eases the pain. For me, it takes less than a 1/2 hour.
Buy some and see if they don't take away some of the burning / pain, etc. If they do, then it's probably gastric-related. If they don't, then get it checked out.
By the way, the DGL helps HEAL inflammed stomach lining, has NO side effects, and is actually pretty good for you.
Hope this helps!
