Hi, I am 22 years old and I have been experiencing chest pains, I get them very often, once or twice a day. The pain is under my left breast more to the center, over my heart. I don't get any other symptoms apart from this pain, but sometimes i have to stop in my tracks and clutch my chest. I was a smoker for 10 years but have stopped for over a year now. I also get these pains when I workout. Is it quite normal to be getting pains like this? I have seen a doctor just a year ago about this but he said he could not find anything wrong with me, but a year has passed now and I am still getting them, surly this should mean there is a reason this is happening?!
