Glass in Elbow

I was attempting to put a sweater on, but every time the sweater would brush my left elbow, I would feel this tiny stinging pain. I ended up finding 6 or 7 pieces of glass in my skin. Some looked really small, like tiny splinters, until you pulled them out. Turns out it was just the tip of the iceberg! I ended up pulling out large pieces of mirror glass! Actually I had someone else pull the pieces out... I don't remember who. At the end, my elbow was bleeding like crazy!
