It happens usually every once in a while, but it's almost like somebody with really sharp nails is poking at my heart(best I can describe it.) It is pretty much always on the left side of my chest, and it usually gives me anxiety the worst cause it is very painful and uncomfortable, it can happen quite a bit when I try to exercise. Of course as always, it goes away eventually. I have had it I would say maybe 15-20 times before.
My usual chest pain is just a sore or ache.
