Upper left side chest pain. Pain at all.

I used to have joundice, anything i eat or drink I belch. Even in early morning I belch. Sometime my upper side of left side chest pain very mild pain. Sometime in my upper left back side pain and sometime left arm pain but pain comes and goes. Most of the time when my chest pains I belch and pain gone. I started talking Sorbiline syrup, pan 40, udiliv 300 for 30 days. Then I had a common cold, I took amoxicillin for 10 days. Now taking Sorbiline syrup, pan 40 and after ecg I have started taking ecosprin av 75. While doing ecg I got nervous and my pulse gone up. Still now I am having pain in my chest thats comes and go. And belching any time. Sometime nose running and difficulty in breathing for few seconds. Please see my Ecg report and advise me what should I do. General physician said Ecg is normal, but I am still worried because after taking ecosprin av 75 I still have pain that comes and goes. Mostly when I sit. I feel pressure on chest. But while working no pain at all.
