It happens once or twice per year ( that i can remember, maybe a bit more )... I get a feeling of "blockage" in my veins or something ( dont know if that's it, it just feels like something like that, im really bad to describe this stuff.. ) Also kind of like a needle pressing my heart, and it goes deeper and deeper... started happening when i was 9-10 yrs old.. smeone told me i just have bad cardio and im not used to it, but i dont know.. i dont remember it happening before 9-10 yrs old.. i'm 16 now.. once i remember watching TV normally, and it happened.. it usually just lasts about 5-6 seconds...
I can do sports, if i go gradually... I dont know if this pain is something normal that happens from time to time like a little indigestion ( >.> ) but yeah... Anyone got an idea? =(

Thank you!
