Hello, My name is Sachin from lucknow. I am 19 years young and my height and weight are 164 c. M and ~55kg respectively. Sometimes I feel internal pain near by my chest and left side in stomach. I am not able to recognize that this pain is rising from chest or stomach. When I press my chest to recognize the pain, nothing happens but when I press left side in the stomach, I feel that pain is moving upward to left side of chest. Is this any heart problem or something else. I never drink, smoke or use tobacco and have healthy food with lots of salad. I also have milk with protinex and usually ride cycle for an hour daily because I take tuitions. What should I do? And please tell me what is the exactly problem? Is there anything serious?
