I/m 25 year old. since last one month, sometimes i am having pain in my chest and arms(left arm specially) and which stands only for a second(max 2 seconds) and which looks like muscle kind of pain. but i visited cardiologist and did all the tests(ECG, Echo cardio dopler test, stress test TMT,
Lipid profile) but after reports doctor said you don't have any heart related problem. so what can be the other cause of this pain? and sometimes also i'm feeling shortness of breath when i/m in tention.
