Hi everyone,

Every now and then I get a strange sensation in the center of my chest. Describing it is tricky, it is like when you get a fright, that shot of, I suppose it is adrenaline, in the center of your chest. It lasts for about a second, sort of catches my breath. It feels a little like something is falling/fluttering inside. It only happens every now and then but leaves me totally terrified. No idea what this is, does anyone else have this sensation? and does anyone know what it is? any ideas would be greatly appreciated,

Thanks alot

Jim
