Hi,im sandeep sharma 31 years old. Sometimes i feel pinching mild pain in my left side of chest,it remains for around 4-6 seconds and at that point of time i can clearly see my heart pumping fast when i put my hand on my chest. I raised it to one of the cardiologist and he asked me to do ecg which came normal. I'm really worried if these are any alarmic signs and should i go for other heart related tests ? to be double sure.
