CHEST PAINS ....(Acid Reflux/GERD related?) please help!!

I am 32 / Male / 170 lbs. I have been having issues with my digestion for the last 3-4 months. I have had a minor issue with accumulating gas which usually relieved by antacid (and occasional Zantac - hardly once a year). trapped gas in my stomach feels like a big ball is suspended just below my esophagus and is being pulled out gradually. This is similar to my symptoms I have had for a long time (6 yrs) but is very rare.

But now the symptoms are a little different: I am getting Chest Pains (stabbing pain) in the upper left chest (around the nipple), sternum, and close to my left armpit. Rarely on the right side. Also new is the occasional upper back pain (between my left shoulder blade and back bone) Does not seem to be connected with meal times. My blood tests showed positive for H.Pylori in Jan/Feb 2010 and was on PrevPac. As soon as I stopped Omerprozole (currently 20mg, twice a day), the chest pains came back.

I otherwise has decent health and moderately active (haven't had to see a Doc in years). No burning sensation (heartburn?), no abdominal pain, no regurgitation, no vomiting, no diarrhea,  no issues with lipids, cholesterol levels are normal, none of the typical GERD / Acid Reflux symptoms, except the Gas & stabbing Chest Pains. The chest area is sometimes sore to touch.

My primary care doc thinks it is acid reflux and I had to beg him for a stress EKG - which came out normal. Can you please let me know what this could be...what else I can do....PLEASE!!
