question: Hi,I am 30 years of age. I am feeling tightness in the middle of my chest. Also I am having faster HR than normal. It is around 90 to 100 at resting. Also I am feeling tightness below jaws.I have consulted some docs. I had ECG twice. My ECG is normal and my Blood pressure is also 130/75.Doc says that it may be due to the Gastric problem. Please suggest what should I do?
