Many years back, (I think) I had a small cyst in my nether region that started to hurt like the dickens. I soaked an xacto knife in some alcohol a started cutting and digging. It did not hurt as bad as I anticipated, but kept bleeding for an hour. I closed it with a small Band-Aid.
When I was a kid I stepped on a big nail that went all the way thru my foot. We were too poor for a doctor, so my mother pulled it out with pliers. Another time she pulled off an ingrown big toenail that got infected. That really hurt. I once got shot in the thigh by some neighborhood thugs on the way home from school. The .22 was just under the skin. My mom cut the bullet out, put in 2 stitches, and sewed up the hole in my pants. The iodine she put on it hurt more than the cutting. She should have been a nurse or a doctor.
About 10 years ago I crashed my motorcycle getting off the freeway (I hit some anti-freeze). My right knee came poking out. I put my knee back in and limped over to my damaged bike. The paramedics came and wanted to take me to the hospital, but I declined. I hitched a ride home, but before I got there I decided I should go to the emergency room. I spent a week in intensive care for a bruised spleen, punctured lung, broken ribs, and spinal damage.
A few years back I had a dark bump on my ring finger. I don't know what it was, but took an xacto knife to it. I kept digging until a large chunk of something came out. I don't remember getting a splinter there, but that is what it seemed like.
