I have been experiencing constant pain, and a burning sensation in my left shoulder, arm and on the left side of my left breast. At times my joints feel painful as well. I have also experienced pain right below the left breastbone and heavy feeling in chest. Constant belching even after meals is also a problem (mostly in an attempt to relieve the feeling as if something is resting on my chest).
A few months ago and I did an ECG test which came back normal (May 2006) and a Barium Meal (March 2006) and the test results were normal.
Any suggestions what this could be?
