I don't think I have posted this one before. A long time ago, I had a huge black head in my nose, right inside, where, if my nose were pierced for a hoop, would be. I couldn't just pop it, it was too painful to touch, well to painful period. I put hot water on a washcloth and held it there for a while, and repeated a couple times to soften it up. I finally got it out, it was thicker than a pencil lead, and a 1/4 inch long.
I have never had it come back, thankfully.
