I'm fairly sure I have a small sliver of metal in my finger. I was doing some DIY a couple of weeks ago, involving shards of metal. My finger became very painful, then excrutiatingly painful. A small cut developed. It's now resolving very slowly. Nothing has come out, and (shameful admission for a sporner, I know), its FAR to painful for me to go rooting around. It's slightly red, very slightly swollen but not hot to the touch or anything.
What will happen if there is a bit of metal in there and it heals over? It's not going to travel and peirce vital organs, is it???
