Ive been having alot of chest pains and weakness in left arm.

I went to cardiologist and had an EKG first. The about 2 weeks later I had a Echocardiogram, then a 10 minute stress test, then right after I had a echocardiogram again.

I wanted to know if 2 cardiologists in the office, said my heart was fine and perfect. DFo these tests rule out all possibilities of Heart problems, maybe the reason for my chest pain and weakness in left arm.

I think you should be reassured that your cardiac function is not responsible for your pain. Your doctors have been thorough with their examinations. However, it is understandable that you would still like to know the cause even if a heart problem seems remote. Did any doctor give you an alternative diagnosis or possible cause ?
Hope you can find out the cause of your discomfort.
