I was getting out of my truck a couple of days ago and I had a mechanical pencil in my hand. the pencil hit the door and the tip jabbed into my thigh/hip. Pulling it out of my leg seemed a bit more difficult than it should have been, but I didn't pay much attention to it. Today I can barely walk. I don't know if pencil lead dust is irritating, or if it is infected, or even if the lead broke off inside, but it really hurts. I'd say I've probably had my fair share of cuts,scrapes, bruises, burns, stabs, slices, smashes, bites, rips, breaks, pulls, sprains, stings, chips and other injuries. I would rate an average puncture wound about a 3 on a 1-10 pain scale, but this one has got to be a solid 7 (comparable to biting your tounge) constantly and a 9 (fingers in door) if touched. Those are pretty high marks for such a minor injury.
