Chest Pain

Jan 2001 I had gallbladder surgery upon my surgeon's recommendation.  However, I still have the chest pain (tightness) soreness and "burps".  I am concerned that there is something more serious that "acid reflux" (I do not have the sour taste, etc...just the pain/nauesa at times).I've been careful in the foods I eat and sometimes even skip the evening meal just so I can sleep at night.

Has snyone else had these symptoms? I recently had the stress test which can back "good"....so its not my heart.
