HOLY SH*T THIS HURT! I just pulled this smooth move 30 min ago out in my shop. I had one last project to wrap up my wife's Camaro for a show tomorrow. I was using a battery drill to drive a screw in, the drill slipped and the phillips bit went through my nail and tore it off. I didn't realize at first that the nail was gone since it was so bloody. I just thought I smashed th crap out of it. I found my nail on my drill stuck to the bit.
Beth wanted me to go to the hospital. So I googled it! Which said to go to the hospital. I called the hospital and they said there was nothing they could do. They just suggested keeping it clean, covered and watch for infection. They said it should grow back.
This post took like 20 min since I'm typing with one hand.
