I am 38 years old male. I have been suffering from GERD since the last three years. I had mild hiatus hernia when the endoscopy was done. Since the last two months I have severe chest pain on the upper part of my chest and underarm on the left side. I got my TMT Echo and ecg done which was ok about a month and a half ago. I can still walk and do some jogging and I don't really feel uncomfortable. The persistent pain has put me under a lot of stress. What should I do.
