that thing that snacks on my diaphragm, just under the heart, behind the sternum, it's back. and it won't go away. i'm surprised the xray didn't show whatever it was, chewing away, slowly and steadily, like the tactile equivalent of a ringing in the ears. something that's there, and you try to ignore, but the more you try, the louder it gets, and then that's all you can hear. like that.
