On Monday of last week as I was teaching a
piano lesson, I hit my right elbow very hard on the edge of the
piano. I felt a sharp stabbing pain in my elbow and as I reached over to rub the spot I felt a soft, spongy, round object begin to move inside my skin as my hand rubbed the painful area. The object seemed to have come (in my mind) from the tip of my elbow but I really don't know what it was.
